TMREEN: The Gym Workout App We Built Ourselves

A look at why ProjexAI built its own gym workout app, and what went into taking TMREEN from idea to a published App Store release.

What TMREEN Is

TMREEN — "Train Smarter Every Day" — is a gym workout tracking app built from an idea by one of ProjexAI's own partners. It's designed for people who want proper structure in their training: tracking sets, reps, and weight with real sequencing, alongside progress tracking, workout history, and nutrition — not just a generic fitness log.

Why We Built It

Freelance personal trainers typically manage clients manually — coordinating over WhatsApp or Telegram, sending workout plans as PDFs or screenshots with little structure or visual clarity. TMREEN was built to solve that specific gap: give trainers a way to build and share real, structured workout plans directly, and give their clients an app that actually organizes what they've been handed.

What We Built

TMREEN is a fully custom React Native app, currently live on the App Store, with an Android release on Google Play coming soon. Beyond core tracking, progress history, and nutrition features, the standout capability is trainer-to-client plan sharing: a trainer builds a workout plan in TMREEN and shares it as a link. If the client doesn't have the app yet, opening the link prompts them to download it; once installed, the plan opens inside the app with an "Add to your workout" option that adds it directly to their schedule with one tap.
