Programs trainers can build once and reuse
Trainers on Trainr author workout programs (linear or cycling), diet programs and their own exercise and meal libraries, then assign them to clients. Clients follow a guided workout with a rest timer.
Fitness app development for trainers, gyms and fitness academies
We build fitness apps that trainers and members actually use: booking and packages, workout and diet programs, check-ins, chat and payments. Trainr, our Dubai personal-training marketplace, is live on Google Play. Proton Fitness Academy, running since 2008, uses our platform for course batches, attendance and certificates anyone can verify at protonfit.com.

What makes fitness apps hard, and how we handled it
Accountability between sessions
Scheduled check-ins with photos and videos, trainer feedback, attendance tracking and 1-on-1 or group chat keep clients engaged between sessions.
Academies, not just gyms
Proton runs academy courses in batches with sessions and attendance, separate student and trainer portals, and certificates verified on a public page.
Payments that fit the market
Stripe for Trainr's packages and classes in the UAE; Razorpay orders and webhooks for Proton's enrolments in India.

Fitness App Development: questions we get asked
Can trainers sell packages and single classes in the same app?
Yes. On Trainr a trainer publishes services, multi-session packages and individual classes; clients book a service or subscribe to a package and pay through Stripe.
Do you build workout and diet tracking, or only bookings?
Both. Trainr includes workout programs with a guided rest timer, diet programs, meal and exercise libraries, workout and diet logs, and scheduled check-ins that trainers review.
Can a fitness academy issue certificates people can verify?
Yes. Proton Fitness Academy issues certificates from its admin console, and anyone can check one on the public certificate-verification page at protonfit.com.
