Questions
Is FitRats really free?
Yes. Meal tracking, workouts and challenges are free, with no subscription. Milo, the AI coach, is free during early access and will later be part of an optional subscription.
Is it on Android?
In early access. You join in three steps at fitrats.app/beta. Google asks new apps for two weeks of testing before they go public on Google Play.
What does Milo do?
Milo is the FitRats AI coach. He estimates calories and protein from your meal photos for you to check, knows your goals and your week, and demonstrates the most common exercises in short videos.
Do I need friends to use it?
No. Meals, workouts and Milo work on your own. Challenges are there when you want company.
Is there money involved in challenges?
Only if your group wants it: a small, capped amount per missed goal, for a cause your group picks or a fund you spend together. Friends pay each other directly; FitRats never handles the money.
Does it work with Apple Health and Health Connect?
Yes. FitRats reads your steps and workouts, and can save your meals and weigh-ins there too.
