What Trainerize does well
A large exercise library. A client app people already recognise. A marketplace if you want inbound strangers. Years of habit in the industry.
Where the week still leaks
Nutrition often becomes a second conversation. Check-ins become a third. Payments become a fourth. That is the six-app problem with a nicer workout builder.
Tarna puts the program, the food log, the check-in thread, and the package on the same roster. The client opens one phone. You open one desk.
AI that stays on your desk
Bring Claude, ChatGPT, or Gemini. Tarna writes a first reply when a check-in lands, and a first pass on the week and the food. You tidy it. Nothing sends itself.
How to leave without losing the roster
Export clients and workouts. Drop the CSVs on Tarna's import desk. Duplicates update instead of cloning. Invite links go out once. Clients install to the home screen and tomorrow's session is waiting.
Studios that want the move handled can use the founding switch at /move.
Questions
- Is Tarna a Trainerize alternative?
- Yes. Tarna is a coaching OS with programs, nutrition, check-ins, habits, messages, and packages for hybrid coaches who want one desk and one phone.
- Can I import from Trainerize?
- Yes. Export clients and workouts, then drop the CSVs on /app/import. Emails match so existing people update instead of duplicating.
