Free AI fitness app builder for coaches
You coach people and the schedule, the plans and the payments live in three different places.
A members' area with sign-in where clients see their own plan and book sessions, and you see who is booked. Built from a description, as a web app your clients open in their browser.
What it builds
- Client accounts, each seeing only their own plan
- A class or session schedule clients can book from
- Plans and progress stored per client, not in a spreadsheet
- Payments through your own connected account
- A public page for people who have not signed up yet
Start from this
A prompt that produces a working one. Change the details to yours.
Build a site for my personal training business. Public pages: what I offer, prices, about me, contact. Then a members' area behind sign-in where each client sees their own training plan and can book a session from my available slots. I see all bookings in one list. Store each client's plan and their session history.

Questions people ask
Can AI build a fitness app?
Yes, as a web app. Describe your coaching setup, and Kleap builds a members' area with client sign-in, personal plans, session booking and a database. Clients open it in their phone's browser and can add it to their home screen. Kleap does not publish native apps to the App Store or Google Play.
How much does it cost to build a fitness app?
On Kleap you can build and publish a first version on the free plan: free usage that refills, published on a kleap.io address. Your own domain needs a paid plan, and the Pro and Business plans add much more usage. Payment providers such as Stripe charge their own fees.
