Contrigraph is a habit tracking application designed to help users focus on a single habit. It uses a visual contribution graph, similar to GitHub's, to display progress over a year.
You can log your daily effort for your chosen habit using five distinct levels: none, a little, okay, solid, and perfect. The app provides a year-long strip and a monthly calendar to visualize your progress and identify patterns.
No, Contrigraph does not contain advertisements. It is a free application with optional in-app purchases.
Contrigraph is available for iPhone and iPad devices, supporting both English and Japanese languages.
Notifications are sent only on days you haven't logged your habit. You can log directly from the notification. A secondary reminder is sent if a streak is active and it's about to break.
No, Contrigraph is intentionally designed to focus on only one habit at a time to simplify tracking and improve adherence.
Contrigraph has an age rating of 4+, making it suitable for a wide range of users.
The latest version of Contrigraph, 2.1.1, was last updated on October 13, 2026.
