FitIL: Mobile app and SaaS

Chapter 1

What the client needed

Trainers in Israel manage clients over WhatsApp and spreadsheets, and trainees forget what they lifted last session. The need was one Hebrew system that anyone can start alone and connect to a trainer later by invitation.

Chapter 3

How it is built

The app is written in React on Vite, with public pages prerendered so search engines can read them. Supabase holds users, workouts and role-based permissions for trainee, trainer and gym owner. The same code is packaged as a store app, and trainers can also work from a computer.
