Metrical
Metrical estimates calories and macros from meal photos or text, then summarizes intake and nutrition trends. It is for people tracking nutrition, including athletes and coaches supporting clients.
Who it's for
- Athletes and runners who want to log meals quickly, including when they are offline.
- Fitness coaches, nutritionists, and personal trainers who recommend lightweight meal tracking to clients.
- People tracking calories or macros who prefer photo or text logging over searching a food database.
How it fits your workflow
Open the PWA in a browser and log a meal with a photo or a written description. Metrical estimates calories and macros, and users can adjust the portion.
Review daily summaries and longer-term insights for intake, macro totals, goals, streaks, and trends. Free-plan data stays on the device, and core tracking works offline.
Optionally purchase Cloud for cross-device sync, automatic backups, saved meal photos across devices, and enhanced AI.
