Knomee 2.06 is avaible on the App Store


Knomee has been evolving every month since the launch of Knomee 2.0 a few months ago.

The last update (version 2.06) introduced two new features:

  • The "dataviz" interface that you get when you click on the calendar on the chart view now displays a calendar with the four previous weeks. Each day is assigned an average performance, with a corresponding colour that tells you if you are meeting your target goals for you quest, or far from them. You may have noticed that Knomee sends you a coloured feedback (an alert) each time you enter a new measure, this is exactly the same principle / colouring that is used for the calendar.
  • The main design principle of Knomee is to help you enter a new self-tracking measure very fast, using the four vertical sliders, one for each tracker. In 99% of the case, this is both precise and efficient ... but sometimes you may want to record a precise numerical value. If you long-press on the slider, and if the tracker is a numerical tracker, you will get the opportunity to enter the value directly though a numerical keyboard.

Most of the changes are bug fixes that we collect through your usage. During the summer, a new version  of the EMLA (Evolutionary Machine Learning Agents) algorithm was introduce to optimize memory consumption.

Another feature that has received continuous improvement is the notification that you receive to prompt you to make a new measure. You have two options (this is decided in the "option" screen that you may access from the home screen). To activate the reminders (notification) you simply switch "Reminders" on. Then you decide between "time" and "cycle". The time option is very simple : you get a reminder once a day if you have not self-tracked recently. You pick the time with the hourly dial on the right. If you select "cycle", Knomee will compute the proper delay for each quest, which depends on which frequency you asked for during setup. You can edit this frequency at any moment by selecting "edit" on the home screen.

You will notice that we have made the design of sliders more self-evident, and we have also improved the on-boarding screens since we got strong complaints from some users. Don't hesitate to share any feedback if you think that we could make learning how to use Knomee easier.

Using Knomee takes a while to get rewarded, since the app needs enough data to provide feedback (the "sense" in "self-tracking with sense" :). The simplest  and usually most interesting moment is when Knomee start to let you know which factor seem to contribute to your quest. You have probably noticed that Knomee colours the trackers in green (background colour) if the tracker plays a positive role, and red if the tracker plays a negative role. In Knomee 2.06  we make this more evident in two ways:

  • on the chart view (the detail self-tracking charts), we have added smiling and frowning smileys to complement the colouring
  • on the main screen (the one with the sliders), we now put a touch of red/green coloring as the mountains background. Thus you get "at first glance" the positive feedback from Knomee as soon as there is enough data, assuming that some of the trackers are significant

Large performance improvements for new Knomee release !


This month's release for Knomee (v2.04) turns out to be quite important, because we were successful to optimize and to reduce Knomee memory consumption significantly. Since iOS kills apps that consume the most memory when it needs to load something new, this behavior (Knomee stopping with no warning because OS killed it) has started to happen before. The improved algorithm is both much faster and less memory-hungry, by a factor of five. This translates in better stability and performance.

As with the previous releases of Knomee 2, this release comes with a number of bug fixes and minor usability improvements. In addition, we have made two changes to reflect some of the comments sent by our users :

  • The main screen, that is used to enter new self-tracking measures, has been using “mountains” representations to give you a quick feedback on how you are doing, with respect to the target that you have set, with each of your quest trackers. Rounded light-green mountains are indicators of success (target reached) whereas rugged dark mountains indicate that you are still far from your target values. To make this more obvious, we have just added a smiley face, happy or unhappy, to the mountain icons. In addition, since 2.04, you may click on the mountain to get an explanation. The weather illustration gives you a trend: a bright sun indicates improvement while rain represents a decline in performance.
  • The Quest Rating interface, that you see when you click on the quest score on the main screen if you have selected the “tech mode” has been simplified. The goal of this interface is both to explain the quest score (from 0% to 100%) and to show the structure of the quest with colors to help you see which trackers help or do not help towards your quest. The new interface is simpler, it show that the score is the sum of three components:  the data score (how much data you have collected), the pattern score (the capability of knomee to extract patterns from your data) and the forecasting score (how well Knomee is doing with its forecasting algorithm). The idea, inspired by Granger causality, is that a good forecasting score is an indication of a good quest (remember that a quest is a "causal hypothesis" that you are trying to prove or disprove).

Knomee has now reached a good usability level and our goal is to develop our reach. There are a number of new competitors to Knomee, which is a good thing, since it shows the need for a truly customizable self-tracking app. However, Knomee is still the only mobile application with embedded AI that gives smart feedbacks and visual analysis of your self-tracking data.

Knomee 2.0 is available on the AppStore


Knomee 2.0 is now available on the AppStore !

As explained in our previous post, this version has a completely new database. The bad news is that you need to reinstall Knomee, the good news is that there are many interesting new features, including "memos", that is the ability to annotate your self-tracking with very short text memos. The re-engineering of the database had become necessary to improve and simplify the app's architecture. For instance, Quests have now more features that will prove very useful if anyone wants to submit a Quest to Knomee public library.

However, the true motivation for this design breakthrough was your request to add annotations. Frankly, this should have been a feature from the very beginning since most academic books about self-tracking report that the ability to add explicit texts to the measures is critical to improve the "ownership". Being able to add your comments about the context for the self-tracking is more that useful : it is mandatory when some exceptional circumstance explain the very specific value (such as being sick and  thus logging fewer steps, being invited for a celebration dinner and logging more food/drink than usual, starting a new prescription and seeing that it makes a difference on your heart rate, etc.)

To create a memo, you simply clock on the calendar button (top of main screen) and you get a new UI that may be used either to change the current time or to add a memo. Memos appear in the measure list (when you ask for a list of all measures in the ChartView screen) but they are also represented directly on the ChartView, as show in the first illustration. Each memo is represented by a small diamond, with a line that displays the text of the memo on the time horizon. This makes remembering the context of a specific measure very simple.

Quests have now an optional "owner" (represented with an email) and a "pitch" : a 2 sentence summary of the purpose and benefits of the quest. The Quest Library has also been improved, but this is only the beginning. Our goal is to make the Quest Library fully open, with its GitHub site, so that anyone can add to the library.  We strongly encourage you to browse through the quest library (see illustration below) and to submit your best quests so that they may be shared with others.

The engine for data analysis through Machine Learning, called EMLA, has also been improved. A few month ago we presented a research paper that explains our 2018 quest to improve the robustness and usability of our EMLA algorithm. Knomee 2.0 benefits from these scientific improvements through better prediction capabilities.  Last, many of the data vizualization UI (user interfaces) have been improved in Knomee 2.0. There is still a long journey to make Knomee as simple to use as it is effective.

When you de-install Knomee 1.9, you will loose your data, but you will keep you quest on your iCloud (assuming that you have activated this option). Therefore, when you install Knomee 2.0, an alert will tell you that your Knomee account has been found and that your previous quests may be re-installed.

If your really want to get your data, you should export it to yourself via email before de-installing Knomee 1.9 and that you can import it back with Knomee 2.0. Don't hesitate to contact "" if you need assistance.

New version on the AppStore – planning ahead for 2019

1. New 1.91 version 

A new version is now available on the app store. It is a minor release since it comes with few changes:

  • It solves Face ID and i-Cloud Bugs. If you have an iPhone X or Xs, you should definitely upgrade. This is mandatory if you want to protect Knomee with personal identification (touch or face recognition).
  • The quest library has been expanded with a few new quests. For instance we have added a quest for pregnant women (how to reduce cramps) and a keto diet quest. Knomee is quite useful to help you monitor your diet and we expect to see more such quests in the future. One team member is using Knomee to track the benefits of the paleo diet with surprisingly good and significant results.
  • The font size on the home screen is now dynamic and adapts to your iPhone model and the type of labels used by your quest.
  • The "quest swipe" capability (the ability to move from one quest to the other by swiping right or left on the home screen) has been significantly improved. This also applies to the "swipe up/down" capability to move from "home" to "chart" view and back.

2. 2018 lessons

Knomee has been available for over a year, it has been a great learning journey from our team. We have managed to recruit organically a fair amount of users, thus gathering very interesting feedbacks. This comes from the analytics  (number of user, various steps that were explored) and explicit comments through email and social networks (such as Facebook and Twitter). The short story is that Knomee is too complex for most users who quit after a few days of exploring the different menus. Fortunately, some of you go further with their Knomee experience, which gives deeper insights.

Our main hard problem is that the value proposition is not perceived by most users. For people who start a self-tracking journey, Knomee ends up delivering lots of value because the quests are personalised and because the insights that are permitted by the quest structure are actually useful. Some users have been able to improve significantly their lives thanks to the behaviour change supported by Knomee. Simply stated, it takes a few weeks of self-tracking before Knomee starts to shine and this is too long for most users.

A key request from you, the Knomee users, is to be able to personalise your tracking with notes, short time-stamped memos that record the context of a measure. This is a very legitimate request, since a self-tracking app is very much like a diary. Also it is a common feature of most mood trackers. Another key interesting message that we hear from our users is  "if I confide my personal data to Knomee I expect a nice display of my data, both pleasant to look at and insightful". 2019 will be a journey towards getting our data visualisation on par with the best professional tools.

3. Knomee version 2.0

The next release will add all the fixes that we have pushed forward during 2018 because they require a database model change. The good news is that we are going to solve irritating problems or add features that our users have been requesting frequently. The bad news is that it will require you to start fresh and reimport your data (quests or measures) ... or start with a new set of quests.

More precisely, here is the current list of features that we are implementing right now:

  • Memos: at last, you will be able to add notes and see them on the chart view, which will become your personal diary.
  • Upgrading our database schema will allow to make a number of choices persistent.
  • Quests will evolve towards an open library model (cf. next section) - where quests authors (a new role, this could be you) will enrich the quest with additional info such as a "pitch description" (why would anyone use the quest) or a feedback email (if you want to share your data). The notion of a "quest author" should match the needs of coaches (from sports to diet) who want to leverage Knomee to promote behaviour practices.
  • As told in the previous section, the "chart view" will improve constantly with better displays of the graphs (data tracking curves) and insights.

The current release date for Knomee 2.0 is April 2019.

4. 2019 strategy

Because our main challenge is a communication problem, our main strategy for 2019 is to listen. The app will continue to evolve to fix bugs as required by our users (after a year of feedbacks, it is obvious that a self-tracking app needs to be flawless), but we have no other plan for new features than those proposed with Knomee 2.0.

On the other hand, you can expect from us a redoubled effort on our communication front, either on this Web site or our social media accounts.

Last, we plan to open-source the library of quests using a GitHub account. Stay tuned, more will be announced after the 2.0 release. Quests are already encoded using an open format. Our new public git site will hold:

  1. Data sample files for fellow research scientists who want to apply their machine learning algorithms to self-tracking data
  2. The set of quests that is offered in the Knomee library. Very soon, this library will be open-sourced : if you upload a quest to our GitHub, it will be part of the next release !

Knomee 1.6 is now available

We will continue to release a new version of Knomee every month and we pledge to improve the application continuously. Knomee really shines when you have defined your own quests but many users complained that creating a new quest was a tedious and error-prone exercise. This is why we have introduced a new “QuestView” in Knomee 1.6. The view makes the quest structure, which is made of "one focus tracker" and 1-to-3 related factor trackers more explicit.

The new quest view (which comes with a cute Quest logo) is used in many ways:

  • When you create a new quest ! this was the most complicated screen in Knomee, the experience is much nicer. We have separated the quest and the tracker editors. We have also fixed a number of bugs that made creating a new tracker difficult.
  • When you click on your KenScore. You can now see a summary of your quest with colors that tell you which trackers have a positive (green) or negative (red) impact. On the previous image, you can see that fat and gluten have a negative impact on the main "fitness" tracker.
  • When you add a quest from the quest library, it makes it easier to pick a quest and customize it to your needs.
  • When you press the edit button from the home screen. You simply click on any tracker (rectangle) to access the tracker editor.

What is coming next ?

We will continue to produce a new release every month to address the iqssues that you are sending us back. Here is the current backlog for the next two releases:

  1. Knomee 1.7 will propose a refreshed "Chart View" (the view that you gent when you click "View" from the home page, or with the eye button on the main page). The key new feature will be the addition of "short term forecasts" for your quest's trackers. This should be fun and will also help us to improve the forecast. You have been complaining about the absence of vertical scale and the fact that the horizontal scale was reacting poorly to zooming. This will be fixed ! 1.7 main goal is to increase the pleasure you get from watching your data 🙂
  2. Knomee 1.8 will propose a massive improvement of all the text that Knomee such as insights. They really look like computer generated statement ... we have found ways to improve on that. We are also going to go deeper with the insights. The list "automated trackers" that you can import from HealthKit will grow, because we want you to better leverage self-tracking from your Apple watch or from great apps such as AutoSleep.

If you are using Fitbit instead of an Apple Watch and would like to import your data into Knomee, there is a great app called sync solver that will help you import your Fitbit data into HealtKit (making it accessible to Knomee)

Remember that the facebook page is waiting for you input or that you can always send us an email at

Knomee is available on your iPhone at last !

Very proud to announce that Knomee is officially available to download on the app store!

This app allows you to track whatever you want and helps you find correlations in your data to learn more about yourself.

Say, for example, you’ve been wondering whether eating breakfast, calling your mom regularly or getting 8+ hours of sleep really have an impact on your sense of well-being. Well, you should probably do all of these but find out which one makes a difference for you! And actually, scratch that, because there are no *shoulds* in knomee. it’s your life, your choice, your data, your results.

If you like it, hate it, want much more from this app, join the Facebook community !
Knomee will grow in 2018, we hope that you will join this adventure.

The Knomee team.

Why in the world propose yet another self-tracker ?

Knomee is a self-tracker app for mood, health, sports, lifestyle … you track whatever you want.

  • Knomee is completely customizable. Knomee works for quantified trackers (weight, elapsed time, heart rate) and qualitative ones (mood, quality of food or sleep, how you feel). Knomee lets you use your own words and define your very own trackers.
  • HealthKit compatible for steps, heart rate, sleep and weight. You may import these values from your phone or connected devices automatically if you want to.

Tracking is not enough, Knomee helps you to define quests, a group of things that you want to track together. A quest may be used to improve your well-being (as defined by the main tracker) through some behaviour changes (as defined by other trackers called factors). You may simply want to understand the effect of these factors on your main tracker, without any idea of change. The quest represents a question to yourself: is there a link between these factors (what you smoke, how you sleep, what you eat …) and your main tracker (how you feel, sleep, how fast you run ….) ? We call this “self-tracking with sense”: you self-track to understand yourself better. You pick a “main” tracker and associate a few (1 to 3) “factor” trackers that you believe to be linked together. Knomee lets you:

  • Track a quest with one screen and one finger (much faster that tracking a set of things separately) with instant visual feedback,
  • Manage multiple quests – Quests come and go, some make sense and some don’t. Knomee helps you to find out quickly what works for you and what does not.

Seeing your data is not enough, Knomee has a built-in data scientist inside. This helps you understand yourself better through your quests.

  • Knomee colors what helps and what does not on your measure tracker screen. Green-colored trackers may have a positive influence on your goal, while red-colored trackers may play against your goal.
  • Knomee proposes “factor analysis” including time, day and location. This helps look at your self-tracking data and make sense of the curves.
  • Knomee gives you insights to help you understand yourself better. After a few weeks Knomee may send you notification from your built-in data scientist.

Self-tracking is quickly boring, so Knomee makes it fun !

  • Knomee uses an AI agent that forecasts what you are going to say next. It saves you time when it’s right … and it’s fun (and interesting because it usually is a special moment) when it’s wrong.
  • Knomee design is optimized for speed : open the app, self-track a couple of measures, and quit in 15 second
  • Knomee uses friendly mountains icons with weather to indicate where you stand with respect to your own targets.

Everything is built in the app and your data will not leave your phone. There are no back-ends, Knomee is not a service. It is a 21st century notebook with built-in smart, visual and fun analytics.
