A habit tracker tuned to one song

Start a habit
with one song.
Grow it at your pace.

Day one is one song long — three minutes, give or take. That's all the habit has to be. After every session you rate it — too easy, just right, too much — and the playlist grows or shrinks to match. Until your habit is the playlist you actually look forward to.

How it works

One song. One tap. One rating.

The hardest part of a habit is showing up. We made the bar so low that "showing up" is just pressing play.

01 — PICK

Choose one song that fits the habit.

Stretching, journaling, push-ups, breathwork — pick a track that matches the energy. Pull it from the bundled library, your Apple Music account, or files already on your phone.

02 — DO

Press play. Do the thing until the song ends.

The song ends, the session ends. You showed up.

03 — RATE

Tell the app how it felt.

Three buttons after every session. Too easy opens the song picker so you can add one. Just right keeps the playlist. Too much lets you pick a song to remove. The habit calibrates to you.

Too easy +1 Just right keep Too much −1
04 — KEEP GOING

Want more? Shuffle a playlist and stay in it.

When the earned tracks finish, tap keep going to shuffle from a playlist of your choice. It loops as long as you want.

Keep going mode

Finished the playlist? Keep going.

When your session ends, the app asks one question: done, or keep going? Tap keep going and it shuffles tracks from a playlist of your choice — bundled categories, your Apple Music library, or your local files. The playlist loops indefinitely. The habit ends when you say so.

Optional · per-session
01 App asks: keep going or done? One tap either way
02 Shuffle from your chosen playlist. Bundled categories, Apple Music, or local files
03 End the session whenever you want. Loops indefinitely — finish on your own terms
Built for showing up

Small details that keep the streak alive.

Live Activity & Dynamic Island

Your session lives on the lock screen and in the Dynamic Island. See the current track, the elapsed time, and pause without ever opening the app.

Per-habit reminders

Set a time per habit and the app schedules a local notification on the days you've picked. No server, no account.

Weekly schedule

Pick the days each habit runs — Mon/Wed/Fri stretching, daily journaling, Sunday-only meal prep. The streak knows the difference between a missed day and a rest day.

Stats that actually help

Current streak, longest streak, total sessions, total time, and a last-7-days minute chart — per habit, all on one screen.
