Worth it?
Is StableFit PRO worth it?
Short answer: for a solo trainer whose clients are scattered across spreadsheets and messengers, it is worth trying, because the first three clients cost nothing. Whether to pay depends on how many clients you coach and whether you need payments or branding.
Weighed on the published pricing and features from stable-fit.com and the App Store listing, read on 2026-10-01. We do not quote ratings: the app is young and its reviews are few.
What you get for free
The free tier covers up to three clients with the full workflow: client cards, questionnaires, programs, progress, nutrition and chat. That is enough to move your first clients over and see whether the app fits how you work before paying anything.
What paying adds
Paying removes the three-client limit. The annual plan at $100 works out cheaper than twelve months at $20. The client app stays free either way.
Who gets the most from it
Trainers who lose time to admin: copying programs into messengers, tracking weight in a spreadsheet and chasing clients for measurements. Putting those steps in one app with reminders is where the time goes back. Trainers who work in Ukrainian also get an interface in their own language.
When to look elsewhere
If you need to take payments from clients, ship an app under your own brand, run group classes or manage a team of coaches, StableFit does not cover that today; Trainerize, TrueCoach or Everfit do, see our personal trainer apps roundup.
Verdict
Worth trying for almost any solo trainer, since it is free for a first few clients; worth paying for once you pass three clients and the one-app workflow saves you real hours. Not the right buy for studios or coaching businesses that need billing and branding.
