- Developer kevinkern vibe-coded a personal fitness/nutrition tracker with Grok Code in a single day, after finding no paid app fit his needs.
- Features include a 'fridge mode' (photo your fridge, get recipes hitting your macros), a gym plan personalized to his injury with Grok-generated images, and saving recipes via Instagram/TikTok screenshots.
- Eating out (e.g., steak) auto-adjusts the rest of the day's meals; the app also has 35 achievements, body trends, and shopping lists—all self-hosted with no vendor lock-in.
