How to build a fitness tracker app with AI
A fitness tracker is the classic first 10x project: data models for workouts, native charts and lists, HealthKit-style UI, and a TestFlight release. The whole thing starts from one prompt.
Step 1: Describe the tracker
Name the workouts, the stats you track, and the screens you want - for example logging, history, and a progress dashboard.
Step 2: Review the plan and design
10x asks four founding questions, then shows a Build Brief with scope. Pick a design direction before anything is generated.
Step 3: Generate and preview native source
The builder emits editable SwiftUI code and boots a simulator preview so you can tap through the real app.
Step 4: Publish to TestFlight
Connect App Store Connect, upload the first build, and invite testers - all from the Release tab.
FAQ
Do I need Swift experience?
No. Describe the app in plain language; the generated SwiftUI stays editable if you do know Swift.
Can it use HealthKit?
Yes. Request HealthKit-backed behavior explicitly in a follow-up turn after the first version exists.
