BodyBy.ai
AI fitness trainer in your pocket
BodyByAI is an all-in-one AI fitness trainer for iOS and Android — adaptive workouts, nutrition planning, and habit coaching, all personalized. Built for DigitalDNA Labs, design lead Scott Cimock.
An AI training partner that adapts every workout and meal plan to the user. The app draws on a 25,000+ workout library and a 50,000+ meal database, adjusting sessions and macros to each person's body, goals, and progress. A 1-tap meal scanner, body scan tracking, video form demos, and habit streaks hold the loop together. We built and shipped the full app — UX, iOS and Android builds, subscription layer — from a single React codebase.
DigitalDNA wanted to compete in a crowded fitness market by leaning into personalization: workouts that adapt to progress, meal plans built around macros, habit tracking that reinforces consistency. Needed a polished cross-platform mobile experience that felt native from day one.
React web app packaged for mobile, shipping to both iOS and Android from a single codebase. Dynamic workout sessions from a library of 25,000+ combinations, adjusting to user feedback. 1-tap meal scanner across 50,000+ meal combinations. Body scanner for progress, video exercise demos, habit coaching with streaks. Full experience: onboarding, workouts, meal logging, progress, subscription tiers (Pro/Elite, monthly/annual).
Launched on App Store and Google Play in May 2025 as free with IAP. DigitalDNA Labs now has a production fitness platform with the AI coaching loop in users' hands.
DigitalDNA Labs now has a launched product with real users in the loop — a foundation to keep tuning the AI coaching engine, layer in new training modalities, and grow the subscriber base. For founders going cross-platform with AI at the core: pick a single codebase early, treat the AI loop as a product (not a feature), and obsess over the first ten sessions a user has — that's where retention is won.
