Layerz
Lets you design a working iOS app, with live data and logic, directly on your iPhone.
Layerz is an iOS design tool that runs on the iPhone itself — you draw with real native components, bind them to a data model, and wire taps to actual behavior like navigating, calling an API or branching on a condition, with no build step and no PC. It can import an OpenAPI or Swagger spec directly, turning endpoints and response schemas into bound UI fields with auth and retries handled as settings rather than code. Finished apps run natively on iPhone, iPad and Mac, and sharing the file lets anyone else run exactly what you built, free, on their own device.
What holds up
- +Runs with no build step — the thing you design is the thing that runs, on-device
- +Imports an OpenAPI or Swagger spec straight into bound, working UI fields
- +Recipients run your shared file for free on their own iPhone, iPad or Mac
- +No PC needed at all — design and run entirely on the iPhone
Mind the limits
- −Native iOS only — no Android output despite being a cross-platform design problem
- −Even its own "Designer" pitch admits "a few limits" on custom components, without specifying which
