Just One: Habit Tracker

Just One is a minimalist habit tracker designed around a simple idea: start with one habit, and build from there.

Track your daily habits with a clean, visual dashboard. See your consistency at a glance with GitHub-style heatmaps, monitor weekly completion rates, and build streaks that keep you motivated.

Track Your Way
- Standard habits with flexible frequency (1-7 days per week)
- Progressive journeys that level up over time (reading 10 min → 60 min, running 1 mile → 5 miles)
- Break habits to track what you're quitting — count clean days and log slip-ups
- Affirmations to celebrate internal wins independent of your main goal

Stay Consistent
- Streak tracking counts consecutive weeks you hit your goal
- Streak Savers let you fill in a missed day so one slip doesn't erase weeks of progress
- Previous-day catch-up prompts help you log yesterday's habits before moving on
- Pause and resume habits anytime without losing your history
