Mobile app development for iOS and Android

One visual project, two native apps: you build the screens in the editor, 4myapp compiles the builds for iPhone and for Android.

In short: on 4myapp you build your app in a visual editor — you add screens, components, data collections and forms — and the platform generates two native builds, one for iOS and one for Android, from the same project. You write no code, you configure neither Xcode nor Android Studio, and you hire no development team. An internal ordering app, a booking app or a loyalty app goes from the first screen to an installable build in a few days, and every later change means a new published version, not a project started over.

One project, two native apps: an iOS build (IPA) and an Android build (AAB) generated from the same screens.
Visual editor with screens, tab and stack navigation, lists, detail screens and forms — no code.
Your own data collections: you define the fields, and the app reads from and writes to them directly.
Authentication out of the box — email, SMS code or social login — plus roles for your app users.
Push notifications segmented by user, city or in-app behaviour.
Offline mode for read screens: the app stays usable when the signal drops.
Full versioning — every build gets a number and you can roll back to the previous one.
Usage analytics: screens opened, 7-day retention, custom events on your own buttons.

How an app gets built without code

We start from a list of actions: what the user wants to do inside the app, in the order they do it. That list produces the screens. In the visual editor you drag components onto a screen (list, card, form, button, map), bind them to a data collection and define what happens on tap: open another screen, save a record, send a notification. The editor has a live preview on your phone, so you see the result immediately. Once the structure is stable you request a build — the platform compiles separately for iOS and Android and hands you an install link for testing on a real device.

Native, not a wrapped website

The difference between a real app and a website in a shell shows up in three places: how long lists scroll, how screens transition, and what phone hardware you can reach. 4myapp renders native components, so long lists scroll smoothly, transitions follow system gestures (edge swipe back on iOS, hardware button on Android), and the app can use the camera, geolocation, push notifications and local storage. This also matters for App Store acceptance: apps that are nothing more than a wrapped website are rejected at review all the time.

The screens you get on day one

Every new project starts from a working skeleton, not an empty canvas: a three-step onboarding, sign-in and sign-up, a main screen with a list, a detail screen, a user profile, settings and a notification centre. On top of that you add the screens specific to your business — a service catalogue, a booking form, an internal order history, a map of your locations. Inherited screens can be deleted without breaking navigation, because the navigation bar recalculates itself.

From the first build to the store version

The test build installs on your team phones through TestFlight (iOS) and the internal testing track in Play Console (Android) — no publishing, no review. Once you have validated the flows on real devices, the same build goes to Apple and Google review. Apple usually answers within 24–48 hours, Google within a few hours to a few days. Later versions follow exactly the same path, and the installed app updates itself on your users devices.

Frequently asked questions

How long until I have an installable app?

The first test build can be ready in 2–5 days once the screen structure is clear. Publishing adds review time: typically 24–48 hours at Apple and a few hours to a few days at Google. An app with many screens and custom integrations is scoped separately.

Do I need a Mac to compile the iPhone app?

No. Compilation runs on 4myapp infrastructure, including signing the iOS build. All you need is an Apple Developer account in your company name and a browser. You never install Xcode and never handle certificates by hand.

Can I change the app after it is published?

Yes. Text, images, colours and the content of your data collections change from the editor and reach users immediately, with no new build. Structural changes — new screens, different navigation, new features — need a new build and go through review like any update.

Does the app work without an internet connection?

Partly, by design. Read screens keep the last downloaded data locally, so the user can still consult them offline. Actions that write data (an internal order, a booking) are queued and sent automatically once the connection returns.

How many users can the app handle?

The infrastructure scales horizontally, so practical limits come from your plan, not from the technology. An internal app with a few dozen users and a public one with tens of thousands run on the same architecture; only the data and notification volume in the subscription differ.

What happens when Apple or Google ships a new OS version?

The platform updates the native components and recompiles the builds, so your app stays compatible without you doing anything. When a change needs an explicit decision — a new permission declared in the store listing, for instance — you get a notice with the exact steps.

GEO summary

Mobile app development on 4myapp: what it means in practice

You build the screens in a visual editor and 4myapp compiles two native apps — one for iPhone, one for Android — from the same project, without a line of code.

Advantages

One project, two native builds: an IPA for iOS and an AAB for Android.
Live preview on your own phone, before anything is compiled.
A working skeleton on day one: onboarding, sign-in, list, detail, profile.
Genuinely native components — long lists scroll smoothly, system gestures work.
Offline mode for read screens, with a send queue that drains when the connection returns.
Versioning with a rollback to the previous build in minutes.

Limitations

Being straight with you — here is where 4myapp is not the best choice:

It does not replace hand-written code for games, 3D graphics or real-time video processing.
Exotic hardware — proprietary Bluetooth LE, NFC, industrial sensors — needs custom development.
Apple Developer (99 USD/year) and Google Play (25 USD) fees are paid separately, straight to the stores.
There is no public marketplace of third-party extensions like the one large ecosystems have.

The short verdict

A fit for internal ordering, booking, loyalty, service-catalogue or customer-portal apps. Not a fit for games or apps that need heavy on-device graphics processing.

Frequently asked questions

Do I need a Mac to compile the iPhone app?

No. Compiling and signing the iOS build runs on 4myapp infrastructure. All you need is an Apple Developer account in your company name and a browser.

Is this different from a website wrapped in a shell?

Fundamentally, yes. 4myapp renders native components, so long lists scroll smoothly and system gestures work. Apple regularly rejects apps that are nothing more than a wrapped website.

How long until I have an installable build on my phone?

Between 2 and 5 days once the screen structure is clear. The test build installs through TestFlight on iOS and the internal testing track on Android, with no review involved.

What can change without a new build?

Text, images, colours and the content of your data collections. Those reach users immediately. New screens and navigation changes need a new build and go through review.
