HabitBull vs OpenHabitTracker

HabitBull is a mobile app for building positive habits or breaking negative ones, available on Android and iOS. It supports yes-or-no habits and numeric targets, including schedules for repeating an activity several times a week. Streak tracking helps users keep a chain going, while reminders can be set for particular times; general reminders can also be disabled in settings. The maker advertises graphs and analytics for exploring habit data, and Android users can enter data from home-screen widgets. The free plan allows up to five habits. A yearly subscription costs $19.99 a year, with the first week free and one year of Premium access. Premium users can sync data between Android and iOS through automatic background syncing, though it is not real-time, and export data as a CSV file. Users can use the app without registering, but progress may be at risk after losing a phone or reinstalling. The privacy policy lists usage data, advertising identifiers, geographic position, and email address among data the app may collect.

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.
