Trainera is an all-in-one platform for personal trainers, online coaches, gyms and studios, on web, iOS and Android, with Apple Watch and Wear OS apps. Trainers build workout programs from a video exercise library, create meal plans with macro tracking, AI food-photo logging and barcode scanning, and track progress with check-ins, habits, measurements and photos. Payments are built in: Stripe, PayPal, cash and bank-transfer tracking, recurring coaching subscriptions with Apple Pay and Google Pay, and program sales. Trainers can run live classes, sell online courses with quizzes and certificates, run a client community and automate follow-ups. Gyms get membership packages, QR check-in that opens turnstiles, class booking, staff permissions, reports and an optional branded app on the App Store and Google Play. AI drafts plans and questionnaires, and a built-in MCP server connects Claude or ChatGPT.
