Everyone told me you need a native mobile app to build a health product.
"Users expect polished iOS/Android experiences." "Nobody trusts a bot with health data." "Telegram is just for memes."

The numbers tell a clear story. MyFitnessPal at $19.99/month requires 45 seconds and 8 taps to log one meal. MacroFactor at $11.99 needs 90+ seconds. NutritionCheckerBot at $3.95 needs 7 seconds — open Telegram, send a photo, done.
