FitRats
Read full descriptionHide full description
FitRats puts your whole day in one ring: what you eat, how you train and the goals you set, with Milo, your AI coach, and a group of friends who keep you honest. YOUR DAY IN ONE RING The ring fills as your day goes. The outer ring is today, the inner ring is your week, and the middle shows how the day is going: green, yellow or red. One look tells you if you're on track. MEALS โข Snap a photo of your plate and Milo estimates the calories and protein for you to check. โข Scan a barcode or search the food catalog. โข Calories, protein, carbs and fat, and saved meals for what you eat every week. โข Meal tracking is free, with no subscription. WORKOUTS โข Follow a plan or build your own routines. โข Log sets, loads and reps, with a rest timer between sets. โข Records show up the moment you beat them. โข Milo demonstrates the most common exercises in short videos. โข Workouts are free too. MILO, YOUR AI COACH Ask Milo about food and training any time. He reads your meal photos, knows your goals and your week, and gets in touch when it matters. WITH FRIENDS โข Start a challenge with your group, with shared goals or each with your own. โข Every day goes green, yellow or red, and your group sees it. โข Day photos, captions and reactions in the group feed. โข Weekly standings and rounds. โข Optional stakes: a small, capped amount per missed goal, for a cause your group picks or a group fund you spend together. Friends pay each other; FitRats never handles the money. ALSO โข Steps, workouts and weigh-ins from Apple Health. โข Home Screen widgets and a Live Activity on the Lock Screen. โข Your weight over time. โข Sign in with Apple, Google or an email code.
