Can I check off habits without opening the app?

Yes. The home screen widget lists today's habits, and tapping one checks it off in place without opening the app. The square on the widget fills immediately.

Can each habit have its own reminder time?

Yes. You set a reminder time on each habit individually, rather than one alarm for the whole app. If you don't want reminders you can decline the notification permission and everything else still works.

Can I reorder my habits?

Yes. Long-press a habit in the list and drag it. Habits don't get stuck in the order you created them.

Can I see more than one month of history?

Yes. The records screen switches between a monthly view and a yearly view, so you can see a full year of squares at once along with each habit's completion rate.

What about habits I only do on certain days?

Choose every day, weekdays, or any specific set of days. The habit only appears on the days it applies to.

Is there a subscription or a premium tier?

No. The widget, reminders, grids and stats are all free, and there is no premium tier waiting to lock what you already set up.

Is my data sent to a server? Do I need an account?

No. There is no sign-up, no login and no server. Your records are stored on your device only.

If it's free, what about ads?

The app is supported by ads, but checking off or adding a habit never triggers one.

Why habit reminders don't arrive on Android, and how to fix it

Short answer: there are usually three causes. Notification permission is off, battery optimization has put the app to sleep, or the app only has one global reminder time that doesn't match when you actually want the nudge. Work through the checklist below and you'll almost always find it.

Missing reminders are the second reason habit apps get deleted

Across low-star reviews of subscription habit and routine apps, "notifications don't arrive" is the most common complaint after forced payment. No reminder means a broken streak, and a broken streak means no reason to open the app again.

The other frequent complaint is a single app-wide reminder: one 9am alarm can't cover an evening habit, so the reminder becomes noise and people turn it off entirely.

Work through this in order

Start at the top; most cases are solved within the first three steps.

Notification permission: Settings → Apps → the app → Notifications, and make sure notifications are allowed along with the specific category. On Android 13 and later, declining the prompt at install means nothing will ever arrive.
Battery optimization: Settings → Battery → app battery usage, and set the app to Unrestricted. If your phone keeps a separate sleeping-apps list, remove it there too.
Exact alarms: Settings → Apps → Special app access → Alarms & reminders, and allow the app. Without it, reminders can drift by minutes or longer.
Do Not Disturb and Bedtime mode: check that your reminder times don't fall inside a DND window, or add the app as an exception.
Per-habit times: confirm inside the app that each habit actually has a reminder time set. A global toggle with empty per-habit times won't fire when you expect.
After a reboot: some phones need scheduled alarms re-registered. Restart and confirm the next reminder still arrives.

Don't rely on notifications alone

A reminder is a helper, not the system. Notifications disappear once dismissed, but an empty square on a home screen widget stays visible all day.

Plenty of people turn reminders off entirely and use only the widget. If notifications stress you out, a widget plus a weekly look at your grid lasts longer.

How Dayfill does it

Dayfill sets a reminder time on each habit separately: stretching at 7:00, vitamins at 12:30, journaling at 23:00. With day-of-week repeats on, the reminder only fires on those days. The notification permission can be skipped during onboarding, and declining it leaves the widget and all tracking working exactly the same.
