Read full descriptionHide full description
FitRats is accountability for small groups of friends. You set a few goals: calories, protein, daily movement, strength sessions per week, steps, sweets-free days, an eating window, a bedtime. Every night you check in with your numbers. FitRats judges the day: green, yellow or red. Your ring closes when the day is green. Then your group keeps you honest. Everyone in a challenge sees each other's days, reacts to check-ins, and stands in a weekly ranking by adherence. A small stake per slip, flat and capped, is paid directly between members. FitRats never touches money. Slips are not the end. A yellow day is erased by a green day right after it. Even a missed day is erased by three green days in a row. The app is built so the day after a slip is where you come back, not where you give up. What you get β’ One ring per day. Outer ring: how close today came to green. Inner ring: your week. The core lights up when you moved. β’ Goals that fit you. Pick a recipe or build your own set. Changes apply from Monday, so every week is fair. β’ A week view per goal, a personal streak, and your weight over time, never fined. β’ Challenges with your group: standings, a feed with photos and reactions, weekly settlement with receipts reviewed by another member. β’ Sign in with Apple or an email code. No password. FitRats is not a calorie counter or a workout planner. It is where your number becomes a commitment.
