At-risk saves
Maya missed her workout
Streakfox spots the slip before it becomes a churn event.

Accent
Same renderer, default state, and theme contract as the editor.
How it works
Live in an afternoon.
01
A user does the thing
Finishes a lesson, logs a workout, sends an invoice — any action you decide matters.
02
Their streak grows
Streakfox counts the day, in their timezone, and shows them the run they're on.
03
The right nudge lands
Milestone rewards when they hit day 7. A save-your-streak moment before they slip.
04
You watch them return
Active streakers, streak health, and retention checkpoints — without building any of it.
The retention system
More than a widget.
The widget is one drop-in component. Add streak cards, week bars, milestone toasts — or build your own on the same API.
