JSON.fit: bulking meal plans

Bulking meals planned around your exact macros, built by the AI you already use instead of ours. So there's no subscription. Pick the foods you like, paste one prompt into ChatGPT or Claude, and import a full week of meals, macros and a shopping list.

Bulking is simple: eat big, hit your protein, train hard. Doing it consistently is the hard part. JSON.fit makes eating enough easy.

WHY IT'S DIFFERENT
Most fitness apps run AI on their own servers and charge you $10 to $20 a month for it. JSON.fit uses the AI you already use, so there's no cost to pass on, and you're never locked into one provider.

No subscription. No ads. No catch.

YOUR DATA STAYS YOURS
No accounts. Your nutrition and workout data never leaves your device. The app collects only anonymous, non-personal usage stats to help improve it.

Built for skinny guys who struggle to eat enough, and for anyone who wants a real plan without the monthly fee.
