Creators and subscriptions
Subscription apps for fitness creators
Believe by Kim French, QDQ by Maeve Madden and Fancy Feats by Lauren Jumps, each built and run as a real subscription business.
- Years
- 2021 to now
- Platforms
- iOS and Android
- Role
- Sole iOS developer on each app, with Android counterparts for all three.
The brief
Creators with big audiences want their own product, not a page on someone else's platform. That means video workouts, programmes, payments and a release every time the content or the store rules change.
Where it stands
Believe holds 4.9 stars from 605 UK App Store ratings and QDQ 4.7 from 49 (November 2026). Kim French's app has been in continuous development since 2021.
The hard parts
- In-app subscriptions, receipts and restores that stay reliable through every StoreKit change.
- HealthKit step tracking, Google Cast and live workouts.
- Programmes and video workouts at the centre of each app.
