A good personal trainer app brings workout programs, an exercise library, workout logging and client communication into one place — so instead of five tools and spreadsheets you work from a single app. With Fitler the trainer pays a subscription, clients use it for free, and you start free.
For a personal trainer, most of the work isn't the training itself — it's the admin around it: writing programs, explaining exercises, tracking completed workouts and keeping in touch. A good personal trainer app brings all of that into one place, so instead of juggling five apps and spreadsheets you work from a single tool.
What a good trainer app must have
- Workout programs you build by day, exercise, sets and reps, and assign to a client in a couple of taps.
- An exercise library with video demos and muscle groups, plus the option to add your own.
- Workout logging — the client records sets, reps and weights, so you see every completed session.
- Per-exercise loading history, so you can tell whether the client is actually moving forward week to week.
- Communication: messages, notifications and scheduled sessions between you and your client.
Why one app beats five tools
When a client's program, exercises and completed workouts live together, nothing slips through the cracks and you stop re-typing data between tools. With Fitler the trainer pays a subscription and clients use the app for free — you start free and only pay as your client count grows.
