Real interactions. Not mockups.

Design an iPhone app.
On your iPhone.

No PC. No code. Design your app the way it actually works — and see it live, right now, in your hand.

Building an app is hard

One idea. Three jobs.
Five tools.

1

Plan it — in a doc nobody reads twice.

2

Design it — in a tool that can't run it.

3

Build it — and find out half of it can't be built.

Three teams, five tools, and a handoff at every step — where ideas get lost and rework begins.

A beautiful design that doesn't run is still just a picture.

However well you design it, making it work is a completely different problem.

And most of “building” is the same work, over again.

Screens. Lists. Forms. APIs. Every app repeats them — and every team rebuilds them from zero.

No PC.
No Code.

Layerz — design your app the way it works.

Native design, pre-built behaviors, zero code. A little to learn, nothing to fear.

How it works

An app is design, data, and behavior.
Layerz is all three — running.

01

Design

Draw with real native components. Auto Layout, stacks, lists, tabs. What you draw is the app.

02

Data

Define your data, bind it to the screen. Change the data — the screen follows. This is where a mockup becomes an app.

03

Behavior

Action Flow: tap → navigate, load, branch, call a real API. “If this, then that.” No code.

04

Run

No build step. No waiting. It just runs — on iPhone, iPad, and Mac. Share the file; anyone can run it.

The difference

Prototypes pretend.
Layerz apps run.

Other tools

  • Screens that look tappable
  • Fake data, hardcoded text
  • “Imagine an API here”
  • Export → hand off → rebuild

Layerz

  • Native components that actually respond
  • Your data model, live-bound to UI
  • Real API calls with real responses
  • The design is the app. Run it.

Built on native iOS — not a web page in a frame.

Who it's for

Whatever seat you're in,
you design the real thing.

Planner

Plan screen by screen. Define the data, connect it — your plan is the app.

Designer

Design with the real components. A few limits, yes — but what you design is what you get. No more “we can't build this.”

Server Developer

Your backend is done? Point Layerz at your API and you have a client — today.

Solo Dev

Prototype fast, then keep going — all the way to a finished, working design.

Hobbyist

Camera, location, sensors, media. Design the fun little app you always wanted.

Features

Everything your app design needs.
Already built in.

Action Flow

Navigate, change data, branch on conditions — “if this, then that.” Connect a flow to any event, no code.

Live API

Import an OpenAPI or Swagger spec with auth and retries, then bind live responses straight to your screens.

Data & Transformer

Design your own data model, bind it to UI, and map API responses to your screens on a visual node canvas.

Camera & Live Filters

A real camera view with 38 chainable filter effects — capture straight into your data or Photos.

Device Services & Media

React to timers, battery, connectivity, and location. Bring in Lottie animations, video, and audio.

Design System

Color and typography tokens, grouped into themes. Switch the theme, re-skin the whole app — light and dark included.

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 design it.
Is this just clickable mockups, like other prototyping tools?
No. Layerz designs are fully interactive. They use real native components, hold real data, run real logic, and can call live APIs — so what you design behaves like the real thing, 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 with Layerz can open it and experience your design for free.
How much does it cost?
Layerz is free to download and try on the App Store and Mac App Store. Start designing today.
