Commitments vs Habo

Commitments is a habit tracker for promises made to yourself and other people. It supports recurring commitments with yes-or-no completion, or quantity tracking using units, targets, and per-tap steps. Users can add photos, receive nudges, and follow streak counts, Sparks, and Streak Freezes. Circles let people share commitments and activity; creating and hosting a Circle requires Commitments+, while joining is free. Pacts are one-to-one shared daily promises, and invitations and acceptance are free. The core free plan also allows ticking commitments, attaching photos, and sending nudges. The app is available on iOS and macOS, with a home-screen widget for iOS and optional Live Activity and Apple Watch companion. Syncing and Circle sharing use Apple iCloud and CloudKit. The maker says it does not operate a backend holding app data and cannot access commitments, entries, or Circles stored in users’ iCloud accounts.

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.
