Fat Fighters

Fat Fighters is a simple, private weight accountability app built around one idea: that small groups of people are better at staying consistent than any app feature.

Instead of calorie counting, macro logging, or public leaderboards, Fat Fighters asks for one thing: log your weight once a day, with a small group of people you trust. That's it.

Key features:

• Once-a-day weigh-in — takes seconds, not minutes
• Private groups of up to 5 people (free) — your numbers are never shown raw to others
• Trend charts so you can see progress over time without obsessing over daily fluctuations
• No calorie tracking, no food diaries, no workout logging
• Works in any browser, no app download required
• Simple pricing: free tier for one group, Pro plan for multiple groups at £2.99/month

Fat Fighters is designed for people who have tried MyFitnessPal, Happy Scale, Libra, or a shared spreadsheet and found them either too complex, too solitary, or too exposing. It replaces the group chat + spreadsheet DIY setup with a proper product.

The core insight: accountability works best in small, trusted groups — not solo, and not in public. Fat Fighters is the only weight tracker built specifically around that mechanic.
