About Seim

We build a habit tracker simple enough to use on the day you are tired.

The Seim team

Our mission

Seim helps you build habits with small things, done often enough. No account, no ads, no fees. Your profile, progress and history live on your own device, synced to no server at all.

This is the real app

What we believe

Small and steady beats big and rare

No 30-day streak is built from one day of determination. We designed the app so that doing one small thing on a tired day still counts as showing up.

Privacy is the default, not a setting

No accounts, no server-side profile storage, no ads, no analytics SDKs. You delete your data from inside the app whenever you like.

A suggestion should say why

Every recommended challenge states the reason it fits your goal and BMI, rather than handing you an unexplained list.

Not a substitute for a doctor

The AI coach does not diagnose and does not prescribe. If you are pregnant, injured or managing a condition, talk to a doctor first.
