Contrigraph
Read full descriptionHide full description
Grow your grass. That's the whole app. "Contrigraph" is short for contribution graph — the GitHub habit of watching squares turn green as you show up. This app takes that feeling and points it at exactly one habit. ■ One habit, on purpose This isn't a multi-habit dashboard. Running, reading, lifting — pick one and track only that. Fewer things to manage is why it sticks. ■ A year-long strip to read your rhythm The band across the top isn't for reading any single day — it's texture. Glance at it and you can tell when you were on a roll and when things slipped, all year at once. Tap it to jump to that month. ■ A month calendar to look back and fix things The calendar is where the real reading (and rewriting) happens. Tap any day, past or present, and cycle its effort. Five honest levels — not counted, not measured: none, a little, okay, solid, perfect. ■ One big button for today No hunting through a grid. Today gets its own button. ■ A nudge only when you'd actually forget Notifications fire only on days you haven't logged yet, and you can log right from the notification. If a streak is alive, a second "before it breaks" reminder follows later in the day. ・Fully localized in English and Japanese ・Dark mode and Dynamic Type support ・Free, with a banner ad No motivation speech required. Just tap today's square.
