Apps for iPhone
and iPad.
Drawn first.
On a real phone.
Draw the screen on a canvas. Say what happens by clicking steps together — there is no scripting language, and that is on purpose. Then press Run: the design is on an actual iPhone within the minute, running real UIKit controls, not a preview of them. Change a caption on the Mac and it changes in your hand — no reinstall, no relaunch.
Three minutes, and every frame of it is the program
Watch it design, run and export an app.
Nothing here is a mock-up and nothing is a screenshot somebody tidied: the film was made by the program driving itself over its own remote channel, which is also why it can be made again after every change. Subtitles are on the player.
Twenty seconds on one object at a time — fourteen of them, from the mailbox and the 3D model to the stamping clock and the areas. Press one; the whole set is on What's in it.

Kontor — the example that ships in the box
Sixty-seven screens. Twenty-six tables. 2.7 million records.
A whole trading company: customers on a map, quotes, orders, delivery notes with the warehouse floor as a plan, invoices, service tickets on a calendar, a parts catalogue in 3D, travel claims photographed off the receipt, payroll, and projects on a Gantt chart. It is not a marketing mock-up — it is the project this program is tested against, and it is one click away on your first launch.
Three decisions the whole product rests on
Worth knowing before you download anything.
An earlier version generated a script, and it was removed deliberately: a text somebody can hand-edit becomes a second source of truth that nothing can read back. The steps are the program. One ordered list per event — and the same list is drawn as a board, listed as cards, and read out as English sentences. Three views, one meaning, nothing to keep in step.
Run installs a real iOS app that reads your project folder and draws it with real UIKit controls. It takes your project's name, icon and bundle identifier, so several of your apps sit side by side on one phone. Simulator or a cabled iPhone — the same folder, and the app cannot tell the difference.
Export writes a standalone SwiftUI app: screens become views, flows become methods, tables become structs, and not one line of Neuridion code goes with it. Prototype here, then keep going in Xcode — or hand the folder to a developer who has never heard of us.
The whole thing, in four pages
Short on purpose. Start anywhere.
Twenty-odd kinds of control — lists, calendars, charts, maps, a warehouse floor, a 3D parts catalogue, a camera that reads receipts — about forty verbs, and the parts nobody advertises, like money that is not a floating-point number.
02 How it worksFour steps: draw the screen, wire what happens, run it on a phone, export it if you want to. You write code in exactly none of them.
03 PricingDesigning and previewing are free, for everybody, for ever. 159 € a year buys the two things that leave the Mac: the build onto real phones, and the Xcode export.
04 RoadmapWhat is built and running today, what is coming, and the things we have decided deliberately not to do.
Seen on a real iPhone
These are photographs of the phone, not the canvas.
Every picture on this site that shows a phone was taken by the app on the device, through its own screenshot channel. Nothing here is a rendering.
The promise
What you build is yours.
Every screen, every control, every step, every example, the whole preview — with no key, no registration and no clock on it. We run no server for you, so somebody who only designs genuinely costs us nothing. You see the whole tool, not a trimmed one.
An exported app never asks anybody for a key, never expires and never contacts us. It is an Xcode project with your name on it. Whether you keep paying is between us and you, and has nothing to do with the people using your app.
159 € a year — 111,30 € for the first year while it is a beta. No per-device fee, no per-app fee, no seat to declare for the people who end up using what you built. Counting devices would mean a number living inside an app you shipped, and we are not doing that.
JSON for the design, CSV for large tables, your pictures as pictures. No invented binary format anywhere. Open it in a text editor, put it in git, hand it to somebody in ten years.
Neuridion Mobile 0.9.0 Beta
It is beta software: keep backups, and expect things to move before 1.0, and the beta itself ends on 1 January 2027. Designing and previewing are free — now and afterwards. Running it on a real phone and exporting the Xcode project need a licence, in the beta as much as after it.
While it is a beta it is cheaper. The code I2NZMWMG takes 30 %
off the first year — 111,30 € instead of 159 €.
