Short answer

How do you build a fitness coaching app without code?

Whether you coach lifting, running, or nutrition, the app is mostly the same parts: client sign-ups, recurring billing, a place to deliver programs, and reminders that keep clients on track. Those parts already exist as APIs. Describe your coaching app to ChatAPI and it assembles them into one product you can charge for — no engineering team required.

You'd type something like

A coaching app where clients subscribe monthly, get a personalized weekly workout plan, log their sessions, and receive an SMS reminder before each scheduled workout.

What ChatAPI wires together

Real APIs, connected with just enough glue code to behave like one product.

Clerk

Sign-up and accounts for clients and coaches

Stripe

Monthly coaching subscriptions and the billing portal

Convex

Programs, client logs, and progress in realtime

Twilio

SMS reminders before scheduled workouts

Resend

Welcome, check-in, and progress-summary emails

What your MVP includes

Questions founders ask

Can clients pay monthly?

Yes. ChatAPI wires Stripe recurring subscriptions plus a customer billing portal, so clients can subscribe, upgrade, or cancel on their own.

Can I deliver different programs to different clients?

Yes. Each client has their own account and assigned program, stored in realtime so updates show up the moment you make them.

Do I need to write code?

No. You describe how coaching works in your business and ChatAPI generates and wires the app around it.
