HabitKit vs OpenHabitTracker

HabitKit is an Android and iOS habit tracker that records daily habits on a year-long grid, with one tile per day. Users can mark or clear today with a tap and fill earlier dates through a habit calendar. It supports Yes/No, Count, and Measure tracking; Count and Measure habits can use daily goals or stay-below limits. Habits may also have weekly or monthly goals. Progress views include cards, checklists, compact overviews, calendars, streaks, and month-by-month completion statistics. The free tier allows four habits, one reminder per habit, and daily check-in reminders. Pro adds unlimited habits, home-screen widgets, charts, dashboard customization, up to three reminders per habit, and data export and import. Habit history stays on the device, with no account required and no automatic sync to a HabitKit server or between devices. Moving data between devices requires a manual export and import. HabitKit supports Siri and iOS Shortcuts actions, but has no Apple Watch app or complication. Pro does not add automatic syncing or individual quit-habit charts.

OpenHabitTracker is a habit tracker for recording habits, planning tasks and keeping notes. Habits can recur daily, weekly, monthly or yearly, with progress measured by repetitions, time or a target quantity. Tasks can include planned dates and times, durations, checklists and timers, while notes support Markdown. Categories and priorities help organize notes, tasks and habits; lists can also be searched, filtered and sorted. The app can import from Google Keep and supports importing and exporting Markdown, YAML, JSON and TSV files. Its web app works offline and stores data on the device without online sync. The self-hosted Docker version stores data online and requires an internet connection. The maker says the app has no trackers and no account. Notifications include daily due-item summaries and reminders before planned task times, though availability depends on the platform and whether the app is open. It supports keyboard navigation, screen readers and reduced-motion preferences, and is available in 20 languages. It runs on Android, iOS, Linux, macOS, Windows, web and self-hosted deployments. The Free plan is free, with no ads, subscription or in-app purchases.
