HabitBull vs Habo

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.

Habo is an open-source habit tracker for building routines on Android, iOS, Linux, and macOS. Users can record a completed habit, numeric entries, missed habits, skips, and notes; progress views show streaks, trends, and completions over time. Reminders, a monthly calendar, categories, reordering, and archiving help organize habits. Tracking works offline, with changes reconciled after reconnection using a Last-Write-Wins CRDT engine. User-created data stays on the device by default. Backup and sync require an account; Habo Sync encrypts data on the device before it leaves, using Argon2id key derivation and AES-GCM with user-controlled keys. The Supabase backend can be self-hosted for free without restrictions. The product also lists data export, backup, home-screen widgets, and a URL scheme for opening the app from Shortcuts and other apps. Habit tracking costs nothing. Habo Sync costs $1.99 a month or $9.99 a year. Habit notes are capped at 400 characters.
