A habit tracker only helps if it fits the way you actually live: your habits, your days and your idea of what counts as a streak. Describe the tracker you want, the AI agent builds a real Android app, you tick habits off in the emulator preview and download the APK. The idea above is a complete first version; edit any line before you build.
What your habit tracker app will have
From the idea above, the agent builds a small, focused app with these screens:
- Today — only the habits due today, each with a big check button, a progress ring and a line like "3 of 5 done".
- Add habit — name, emoji, color, the weekdays it repeats on and an optional reminder time.
- Habit detail — current streak, best streak, completion rate and a calendar heatmap for the month, so a gap is easy to spot.
- Reminders — one notification per habit at the time you picked, scheduled on the phone itself.
- Settings — reorder or archive habits, choose the first day of the week and switch between light and dark.
All of it is saved on the phone, so the tracker opens instantly and keeps working in airplane mode.
Features you can ask for
Put any of these in your first message, or add them once you have used the app for a few days:
- Counted habits ("8 glasses of water") and timed habits ("20 minutes of reading") next to simple yes/no ones.
- Rest days or a streak freeze, so one missed day does not wipe out a month of effort.
- Habit groups such as Morning, Work and Evening, each with its own reminder.
- A short note on any check-in ("ran 3 km, legs heavy") that shows up on the calendar.
- Weekly and monthly charts plus a "strongest day of the week" insight.
- Badges at 7, 30 and 100 days, with a small animation when you earn one.
- A "yesterday" button for people who log their day at breakfast the next morning.
Ideas to make it yours
People track very different things. Copy one of these into the box above and adjust it:

Get it on your phone
- Press Build this habit tracker app and sign in with Google. The agent starts building right away.
- Tick a few habits in the emulator preview and fire a reminder from the Simulate panel to read how it looks.
- Ask for changes in plain words: "move the streak to the top", "make the check button bounce", "start the week on Monday".
- Press Download APK, allow installs from your browser once, and install the app on your Android phone. From now on the reminders fire on time, even when the app is closed.
- Want it on Google Play? Build the signed APK and AAB from the same menu; the APK builder page explains signing and uploading.
Start with three habits, not ten. Use the app for a week, then tell the agent what bothered you — "I log at night, so show yesterday too" — and the second version will fit you far better than any ready-made tracker.
Why build your own habit tracker
Ready-made trackers are designed for everyone, which makes them a little wrong for everyone: too many screens, streak rules you disagree with, reminders you cannot word the way you like, or features hidden behind a sign-up. When you make your own, the tracker does one job exactly your way and nothing else. A runner can tie habits to training days; the fitness app guide shows how to grow it into a full workout log. A teacher can build a reading tracker for a class, and a small team can keep a shared list of daily routines. Because the simple version keeps its data on your phone, nobody else sees what you are working on, and the app is still there, unchanged, next year.
Frequently asked
Will the habit reminders work when the app is closed?
Yes, on a real Android phone. Reminders are local notifications scheduled on the phone, so they fire at the time you set even when the app is closed. In the emulator preview you trigger them from the Simulate panel to check the wording.
What happens to my streak if I miss a day?
Whatever you decide. Ask for strict streaks, a weekly rest day that does not break the streak, or a streak freeze earned every seven days. Write the rule in your request and the agent builds it in.
Can I track habits that are not a simple yes or no?
Yes. Ask for counted habits such as eight glasses of water or twenty pages, and timed habits such as ten minutes of stretching. The check button becomes a counter or a timer for those habits.
Is my habit data private?
In the simple version everything is stored on the phone and never leaves it. The tracker works offline, and nothing is shared unless you ask for accounts and a hosted backend.
How do I get the habit tracker on my phone?
Press Download APK in the builder, open the file on your Android phone and allow installs from your browser once. The free plan includes a free APK download.
