OpenHabitTracker

OpenHabitTracker doesn't use a streak counter
You won't feel demotivated when you skip a habit once because you won't have to start your streak from zero

It tracks the time elapsed since your last task completion and compares it to the task's repeating interval:
- A task with a 10 day interval which is 2 days overdue is at 120%
- A task with a 4 day interval which is 2 days overdue is at 150%

It allows you to easily prioritize your tasks based on their level of urgency
