Analyze what you tracked to make data-driven health decisions.

Take quantifiable notes
Everything we do impacts our health. The amount is often the difference between healthy and unhealthy. So we made jDay notes quantifiable. For each note that you take, you can pick an Amount, Measurement Unit and Influence that it had on your health.

jDay learns from your past notes and predicts the amount while you are still entering note text. Everything happens locally on your device and predictions only get smarter over time!

Customize everything
With jDay, you can create, edit and delete categories, tags, units, entries, and notes. You can also reorder categories to make jDay customized to you & your goals.

Automatically track routines
No need to manually track the same thing every day. Instead, use a Planner to schedule your routines and avoid the need for boring, error-prone, manual tracking.

Tag your entries
#Meat, #Caffeine, #Rested, #Cardio, #PainKillers, #Happy, #Sick, #LostWeight
are just some of the tags you can use to make your entries even more insightful.

No ads
We care about your privacy. This is the reason we'll never show 3rd party ads. The data you enter is yours. We'll never sell, rent or monetize your personal data in any way.

If you like jDay, consider buying a Premium Subscription. It supports the development and it helps me to make jDay better.
