Boxhabit - Habit Checkbox Grid

Boxhabit is a minimal habit tracker built around one idea: a grid of checkboxes.

Each row is a habit. Each column is a day. Tap a cell to mark it done. That is the entire interface.

FEATURES:
- Add up to 20 habits displayed in a scrollable monochrome grid
- Tap any cell to toggle completion for that day
- Long-press any cell to attach a short note
- Monthly summary row showing raw completion counts per habit
- Navigate between months to review past data
- Brutalist dark interface with monospaced typography

DESIGN PHILOSOPHY:
Boxhabit shows your data as-is. No streaks, no badges, no motivational quotes, no colors to decode. Just a grid that tells you what you did and what you did not do.

PRIVACY:
All data stays on your device. No account required. No analytics. No ads. No internet connection needed.
