The white-label fitness app built for personal trainers.
Stop trading hours for clients. Launch your own branded coaching app on the Apple App Store and Google Play in 10 days. Scale beyond 1-on-1, keep your clients, grow your brand.
You're great at training. The business side is killing you.
Every personal trainer eventually hits the same wall: there are only so many hours in a week. You can charge £60/hour for in-person sessions, max out at 30 sessions a week, and that's your ceiling. £93,600/year if you never miss a session.
Meanwhile, your followers are sliding into your DMs asking for programs you could deliver to 500 of them as easily as 5 — if you had the right platform.
That's what Saisei does for personal trainers. We turn your client roster into a subscription business — without losing the relationship.
Your own fitness coaching app, your name on it.
A complete branded coaching app — for trainers, by people who've shipped 200+ apps:
- Your name on the Apple App Store and Google Play (not "Saisei")
- Workout program builder — week-by-week, drag-and-drop, video demonstrations
- Subscriber-tiered plans (e.g., £15/mo basic, £40/mo premium, £100/mo VIP)
- Push notifications for accountability ("Today's workout is ready")
- Progress tracking — your clients log workouts, you see who's consistent
- Direct payment processing — clients pay you, Saisei takes a small flat fee
- Macro-tracked meal plan builder for when you offer nutrition coaching
- Optional 1-on-1 messaging for premium tiers
From 30 clients a week to 300 a month.
Here's the math that makes most personal trainers move to Saisei:
| Model | Capacity | Monthly revenue |
|---|---|---|
| In-person, 1-on-1 @ £60/session | 30 sessions/week | ~£7,800 |
| Saisei coaching app @ £25/mo per subscriber | 100 subscribers | £2,500 |
| Saisei coaching app @ £25/mo per subscriber | 300 subscribers | £7,500 |
| Saisei coaching app @ £25/mo per subscriber | 500 subscribers | £12,500 |
At 500 subscribers paying £25/mo each, you're earning more from your app — passively, while you sleep — than you do at the gym. And you didn't lose your in-person clients. You added a layer on top.
How it compares to Trainerize.
Both platforms serve personal trainers. Here's the honest comparison:
| Factor | Saisei | Trainerize Custom Branded App |
|---|---|---|
| Built for | Creators + trainers scaling via subscriptions | Studios + multi-coach teams |
| Launch time | 10 days (after dev account setup) | 4+ weeks (Studio/Enterprise tiers) |
| Branding depth | Full white-label, your name in App Store | Pro tier adds branding; full white-label is Studio+ |
| Pricing | From £79/mo (Shodan) — transparent tiers | Custom quotes, typically higher entry |
| Subscription model | Subscriber-tier scaling, decreasing rev share | Per-coach pricing, no rev share |
| Best for | Solo PT scaling 50-500+ subscribers | Studio with 5+ coaches |
What trainers are saying.
"I was capped at 35 in-person clients a week. Six months after launching with Saisei, I have 280 subscribers paying £29/month. That's more revenue than my best month in the gym — and I haven't dropped a single in-person client."
— Sarah Chen, Personal Trainer, London
"The 10-day promise sounded too good to be true. We hit Day 11 because Apple sent back one screenshot question. Honestly, that close to the promise is incredible — Trainerize quoted us 6 weeks."
— Marcus Ali, Strength Coach, Manchester
