FOR PTS WITH IN-PERSON AND ONLINE CLIENTS
Run your whole coaching business from your phone.
Other platforms park the trainer tools in a web dashboard. Fitness Fever puts programme building, structured set tracking, chat and bookings in the app — with a web backend when you want the big screen.

A TRAINER APP, NOT JUST A CLIENT APP
EVERY SET STRUCTURED
0% PLATFORM FEE ON YOUR SALES
EVERYTHING INCLUDED — NO ADD-ONS
TRACKING
Every set structured. No free-text mess.
Programmes arrive as real sets — reps, targets, rest, demo video — not a paragraph to interpret. Clients log each set as they train, so personal bests, streaks and progress compute themselves. You see it the moment it happens.
1,891
exercises with demo videos
2
demo variants — male & female
0

HYBRID
In the gym and online. One app.
Most platforms are built for online-only coaching. Fitness Fever tracks session packages — purchased against used — books in-person sessions on your calendar, and takes attendance, alongside everything your online clients do remotely.
- Session packages: sold, scheduled, counted down automatically
- Your calendar and attendance, in your pocket
- Same app for the client training beside you or three time zones away

WHY THIS EXISTS
Built by the client, not the coach.
I'm Derek. I'm not a personal trainer — I'm a personal trainer's client. For years I watched my own programmes arrive as free-text boxes in the apps my trainer used. No structured sets, no real tracking, no way to see a PB coming. And everything the trainer actually needed lived in a web dashboard she never opened.
So I built the app I wanted to train with: every set structured, 1,891 exercises with proper demos, and the full trainer toolkit on the phone.
No fake testimonials, no invented user counts — it hasn't launched yet, and I'd rather get it right than get it out. If that sounds like your kind of app, the launch cohort is open.

Questions
iOS (submitted to the App Store; early access via TestFlight now) plus a trainer web dashboard in any browser. Android is in development for later in 2026.
Everything: the client app, workout builder, structured tracking, chat, session booking, habits, the storefront, the exercise library. No add-ons, no upsells, no per-client fees.
You connect your own Stripe account. Buyers pay you directly — we never touch the money and take no cut. Stripe's standard card processing fees are the only fees. You handle refunds and taxes as the merchant of record, like any business.
