What is Habo?

Habo is a fast, minimalist habit tracker that respects your privacy. No accounts required. No data harvesting. No clutter, just a clean, focused tool for building routines that stick.

Habo 4.0 ships cross-device sync with end-to-end encryption, automatic encrypted backups, and full self-hosting support. Your habit data is yours, always.

Features

☁️ Habo Sync: E2E Encrypted, Zero-Knowledge

Your data is encrypted on your device before it ever leaves it. The server sees only ciphertext: we cannot read your habits, notes, or streaks. Not even if we wanted to.

• Data encrypted locally with your Master Password before upload
• Zero-knowledge architecture: no plaintext ever touches the server
• Device-generated encryption keys
• Automatic encrypted backups: switch phones without losing your history
• Self-hostable: run your own Supabase backend, free forever

📱 Core Tracking

• Multiple completion types: yes/no, numeric, skip (doesn't break streaks)
• Notes & comments: add context to each check-in
• Smart reminders: gentle nudges at the right time
• Calendar view: see streaks and completions on a monthly grid
• Statistics: streaks, trends, and completions over time

🎨 Personalization

• Dark, Light, and OLED themes
• Material You support (Android)
• Custom button colors
• Drag-and-drop habit reordering
• Categories to group habits by theme

🔒 Privacy & Control

• Offline first: everything works without an internet connection
• Biometric lock: Face ID, Touch ID, or passcode
• Export & backup: own your data, always
• Archive: pause habits without losing history
• URL scheme: deep-link into Habo from Shortcuts and other apps
• Open source: GPL-3.0 licensed, auditable, forkable
