Habit Calendar Widget: Stamp

One goal is enough. Circle Calendar Widget keeps only what matters — a single goal line, a stamp on each day, and a home-screen widget you see every day.

How it works
1. Write your one goal at the top. (e.g. "Work out 30 min", "Drink 2L of water")
2. Tap a day to stamp it — a circle (○) if you kept it, a triangle (△) if so-so, an ✕ if you missed it.
3. Tap again to change the stamp. Just like the "well done" stamps from grade school.

The home-screen widget is the heart of this app
- Put the widget on your home screen and see this month's goal and stamps at a glance.
- You stay aware of how consistent you've been — without even opening the app.
- After midnight the widget rolls over to today on its own (the part other apps often get wrong).
- Tap the widget to open the app and stamp right away.

A gentle daily reminder, too
- Set your own time and message, and get a nudge every day. (e.g. 10 PM "Did you keep your goal today?")

10 calendar skins for every mood
- From a minimal developer-style grid to urban monochrome, sweet pink, dark neon, cream pastel, sage green, ocean blue, sunset peach, retro pixel, and mocha brown.
- Switch a skin and the whole calendar, widget, and stamp colors change with it.
