What platforms is Ratz available on?
Ratz is available on iOS and Android. Download it from the App Store or Google Play.
How do streaks work?
Your streak counts consecutive days with at least one completed workout. Miss a day and it resets to zero. Your all-time max streak is saved so you always have a record to beat.
