Track everything that impacts your health. Analyze your data, plan your actions & improve your health by making data-driven health decisions.

What can I do?

Track anything you want
Select health categories that are important to you and jDay will adapt itself to your tracking needs.

Create healthy habits
With atomic habits inspired Planner you can plan what you want to do, when, where & for how long. jDay will show a notification for every plan that you schedule.

Make data-driven health decisions
Tracking is only the first step. Once you have some data tracked you can apply filters to get valuable insights.

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
You can use custom tags to make your entries easier to analyze.
