Build real iOS apps.
Without code.
Layerz is a visual tool to design your screens, add real data and logic, and connect live APIs — then run it instantly. No build step, no code. Your design works like a real product from the very first minute.
How it works
An app is design, data, and behavior — in one place
Most tools give you one piece. Layerz unifies all three, and runs them the instant you create them.
Design
Drag native iOS components onto the canvas. Auto Layout, stacks, lists, tabs, and reusable components — what you draw is the real thing.
Add data
Define your own data and bind it to the UI. Change the data and the screen updates on its own — the line between a mockup and a living app.
Add behavior
Use Action Flow to make it do things: navigate, change data, branch on conditions, and call real APIs. “If this, then that” — no code.
Run it
No build. No waiting. It runs instantly on iPhone, iPad, and Mac. Switch device and theme on the fly, then share it with anyone.
Features
Everything you need to build a working app
From design to data to behavior to live APIs — all in one place, no code required.
Action Flow
Define how your app behaves without code. Navigate, change data, run number and text logic, and branch on conditions — “if this, then that.” Connect a flow to any event: a button tap, a screen appearing, a search.
Real API Integration
Connect your app to the real world. Import an OpenAPI or Swagger spec from a file or URL, with auth, retries, and per-status responses — then bind live data straight to your screens.
Design with Data
Create custom data structures and enums directly inside the app. Bind data to UI components and see changes reflected automatically.
Instant Preview
See your work come to life immediately. No build process, no waiting — what you design is exactly what you experience, on iPhone, iPad, and Mac.
Native Components & Layout
Design with precision using Auto Layout, stacks, lists, and tabs — the full power of native UIKit components, not a web wrapper.
Reusable Components
Create custom components and reuse them across scenes. Update once, apply everywhere for a consistent design system.
Who it's for
Built for anyone with an idea
From first-time makers to seasoned developers — Layerz meets you where you are.
Makers
Have an app idea but don't code? Build the real thing — not just a picture of it — and put it in people's hands.
Product managers
Validate an idea with a working demo before spending an hour of engineering. Real data, real flows, real “what happens when.”
Designers
Your prototype stops pretending. Real components, real interactions, real behavior — interactive instead of just looking interactive.
Developers
The fastest path to a working spec. The Layerz document is the app, defined as data — go from “what if” to “try it” in minutes.
FAQ
Questions, answered
- Do I need to know how to code?
- No. You design visually, define data, and add behavior with Action Flow — all without writing code. If you can describe what your app should do, you can build it.
- Is this just clickable mockups, like other prototyping tools?
- No. Layerz apps actually run. They use real native components, hold real data, run real logic, and can call live APIs — so what you build behaves like a real product, not a slideshow.
- What can my app connect to?
- Any HTTP API. Import an OpenAPI 3.x or Swagger 2.0 spec (or a JSON Schema) from a file or URL, configure auth and retries, and bind the responses straight to your screens.
- Which devices does it work on?
- iPhone, iPad, and Mac. It's one project you can pick up and continue on any of your Apple devices, and you can switch device and theme while you design.
- Can I share what I build?
- Yes. Share your .layerz file and anyone can open and run it in Layerz for free.
- How much does it cost?
- Layerz is free to download and try on the App Store and Mac App Store. Start building today.
