The Challenge
We wanted a personal health system that would tie together the pieces people usually track in separate apps, nutrition, sleep, recovery and training load, and reduce the manual logging effort with AI, while keeping the science behind the coaching (HRV) credible rather than gimmicky.
Our Solution
We built Calio with FlutterFlow for the iOS and Android app, Supabase for data and authentication, and Claude Vision for meal-photo calorie analysis. The app combines barcode-scan food logging, AI photo calorie estimation, weight tracking, and sleep, recovery and training-load tracking, with AI coaching based on HRV science. It's in production today at usecalio.com.
