Theron - Gym & Nutrition
Health & Fitness
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
New: set and rep suggestions built from what your client actually lifted last session. Write the program once, assign it to twenty. Nutrition included, not an add-on.
Theron is the client record for coaches who write both the training and the food.
WRITE ONCE, ASSIGN TO TWENTY
Build a workout or meal plan as a reusable template, then assign it across your roster and adjust per client. Most coaches find five or six templates cover the majority of their clients, so the forty minutes a program used to take becomes four.
SUGGESTIONS THAT COME FROM REAL DATA
Add an exercise and Theron offers three options for sets and reps: repeat the last session, add load, or add volume. The numbers come from what this client actually logged, so you will never see a weight they have not lifted. If they reported the last session as easy, the suggestion goes up. If they reported it as hard, it comes down.
NUTRITION IS INCLUDED, NOT AN ADD-ON
Meal plans, macro targets and food logging live on the same client record as the training, not in a second tool you pay for separately and reconcile by hand. Clients log a meal by photographing it: the camera reads the plate and fills in the macros.
SEE WHO IS DRIFTING, WHILE YOU CAN STILL CALL THEM
One screen shows who is following the plan, who has gone quiet, and when each membership expires. Plan history keeps every program a client has run, frozen as it was, so when they ask what they did three months ago you can answer.
FOR YOUR CLIENTS
Clients download the same app and get their plan, their workouts and their food log in one place. No separate app to install, no extra charge.
WHAT IT DOES NOT DO
Theron is not a gym till, a door system or a class booking tool, and it does not run your email campaigns. It keeps one accurate record per client and keeps it current.
PRICING

Set and rep suggestions. Add an exercise to a client's plan and Theron offers three options built from what they actually logged last session: repeat it, add load, or add volume. Weights round to real plates, and the suggestion adjusts to how hard they said the last session felt.
Plan history. Every program a client has run stays on their record, frozen exactly as it was, even after you edit or delete the template.
One subscription instead of three. Premium unlocks everything: AI food scans, barcode scanning, the meal and workout planners, AI plans and AI insights. Existing Burn and Peak subscribers keep their current plan and limits.
