Small enough for a tired day

SEIM does not ask you to track everything at once. You pick one habit, do a few small things in it each day, and watch your streak move.

A roadmap for every day

Each habit breaks into small tasks, day by day. You can see where you are today, what tomorrow asks for, and which days you missed.

Suggestions built from your profile

SEIM uses your goal and BMI to put the 3 best-fitting challenges at the top, each one labelled with the reason. Change your goal and the suggestions change with it.

Streaks and stats

Mark each day you finish. Follow your current streak, your record, your completion rate, and charts for the last 7 and 30 days.

Reminders and daily photos

Set a reminder time per challenge, and it still fires after a restart. Take one photo a day and compare them over time — the photos never leave your phone.

A tour of the app

Every screen below was captured from the Android build. Nothing here is a mock-up.

Challenge picker listing the available habit packs

Pick a challenge and start it

The library holds 44 habits across 7 areas, each broken into small daily tasks. Run as many as you like at once, and switch between them from the strip at the top.

Roadmap view listing the days of a habit

See the whole roadmap

Every challenge opens into a day-by-day view: where you are, what comes next, and which days you skipped. No guessing what tomorrow expects of you.

AI coach conversation in Vietnamese

Ask the AI coach

Chat in Vietnamese or English about training, sleep or diet. It reads your profile and current progress, and tells you to see a doctor rather than guessing.

Reminder settings with a time picker per challenge

Reminders that actually arrive

Each challenge carries its own time, scheduled by the phone itself, so notifications still land after a restart. No account and no server involved.

Settings screen listing the AI data controls

You stay in control of your data

Turn health context sharing off, clear the AI history, or start over with a fresh profile — all from Settings, all permanent, all without contacting anyone.
