Most trainers who look for software end up comparing ABC Trainerize, TrueCoach and Everfit. StableFit PRO is a newer, leaner option aimed at one trainer with their own clients. Here is how it lines up on what each is built to do.

Trainerize is a full coaching business platform: programs, nutrition coaching, habits, groups, automated payments and custom branded apps, aimed at everyone from solo coaches to gyms, with a 30-day free trial. StableFit covers the core of one-to-one coaching, client cards, programs, progress, nutrition and chat, without payments or branding, and stays free for your first three clients. Pick Trainerize when you sell packages and want your own branded app; pick StableFit when you want the core workflow simple and cheap.
TrueCoach centres on the workout builder: templates you copy between clients, a library of more than 3,000 exercise videos and the option to upload your own, plus chat, payments and your logo, after a 14-day free trial. StableFit has a ready workout library too, and adds client-side nutrition logging and measurement reminders, but has no client payments or branding. If your coaching is mostly programming with video demos, TrueCoach is purpose-built.
Everfit is a broad platform for online coaching businesses and studios: coach and client apps on iOS and Android, forms and questionnaires, macro-based meal plans with AI meal scanning, broadcast messaging, automation and a custom branded app, priced by client count. StableFit overlaps on questionnaires, nutrition and chat, in a smaller package for one trainer, and adds a Ukrainian interface.
StableFit wins on simplicity, a real free tier for a first few clients, a free client app and Ukrainian language support. It is behind on payments, branding, automation and team features, and as a young app it has a smaller ecosystem than these longer-running platforms. See all options in our personal trainer apps roundup.
Choose StableFit PRO if you coach your own clients and want programs, progress, nutrition and chat in one inexpensive app, especially in Ukrainian. Choose Trainerize or Everfit if you run a coaching business that needs payments, automation, a branded app or a team. Choose TrueCoach if programming with exercise videos is the heart of your work.
StableFit is free for up to three clients and then $20 a month or $100 a year. Trainerize prices depend on plan and client count; check its pricing page for current numbers.
