SevenGrid: Calm Habit Tracker

SevenGrid is a calm, simple weekly habit tracker with home screen widgets. 7 days. 1 grid. Track daily habits and weekly goals on one screen: every habit is a row, every day is a tap. Free to use, with an optional one-time upgrade. No ads, no account, no subscription, and it works fully offline.

Home screen widgets
SevenGrid comes with five minimal widgets: the full week grid, a Today checklist, a clock with the habits you pick underneath, a single habit, and a heatmap of one habit across months. On four of them, one tap checks off today without opening the app. You choose: your count against a target or limit, names or icons, a light, dark, or app-matching look, how much wallpaper shows through, and six clock faces. All five are free.

No streaks
Miss a day and nothing resets: the day stays empty, and every new week is a clean slate. There is no chain to break, so getting back on track is just the next tap. Sick or away? Skip the day: a quiet stroke marks it as a rest day, not a missed one, and the reminder pauses. You can also give a habit a fixed day off, say every Friday.

Free version, one-time Pro
The free version gives you 3 habits, the last 4 weeks in your grid, 2 themes, and all five widgets. It has no time limit and needs no sign-up. Pro is a single purchase: unlimited habits, your full history in the grid, per-habit reminders, the “shape of your week” statistics, and all 20 themes. Pay once. No subscription. Ever.

A two-minute weekly reflection
The grid shows what you did; the weekly reflection asks how it went. Three short questions and your mood, about two minutes, like a small habit journal. Missing a week is fine. Every so often an old entry resurfaces, and a small card sets your mood next to your active days.

Goals that fit your life
Gym three times a week, reading every day, 8 glasses of water a day: each habit gets its own rhythm and the grid adapts, so you can build a daily routine at your own pace. For things you want less of, use an “At most” goal: at most 1 coffee a day, fast food on at most 2 days a week. Stay within the limit and that counts as a win. Go over and nothing turns red. Your week can start on Monday, Sunday, or Saturday.

Statistics without numbers
Which day does the most for your week? When do you rest? How have your weeks felt? With Pro, SevenGrid answers in plain sentences, drawn from your grid and your reflections. Free or Pro, every habit has a 16-week trend graph and a 52-week heatmap with month labels, a habit calendar for the whole year.

Reminders
Everyone gets a gentle daily reminder. With Pro, each habit gets its own reminder with a check-off button in the notification, and every weekday can have its own time.

The quiet extras
- Add a note to any day: long-press its cell
- Log amounts and durations (km, reps, pages, hours) as a record, never as a target
- Share a week as an image, with the habits you pick
- Icons and colors for every habit
- 20 hand-tuned themes, from light to true OLED black, plus automatic dark mode
- Optional daily backup: CSV files with an open schema in a folder of your choice. The backup survives a reinstall; to switch phones, copy that folder over
- A Quick Settings tile that opens the app, and a long press on the app icon to add a habit

Private by design
Your habits stay on your device. No account, no cloud sync, no usage tracking. The app only goes online to check your purchase and to send anonymous crash and error reports, which you can turn off. An independent Exodus Privacy scan confirms it: no analytics, no ad trackers, just the crash reporter. The app works in airplane mode, too.

Built by one person who uses it every day.

Recent changes:
Fixes a crash that some home screens triggered after adding a widget. If the home screen reports an impossible widget size, or none at all, SevenGrid now draws the widget at its default size instead of leaving it empty, and the app opens normally again.
