Who it’s for

Built for founders and product teams.

Here is where it works best, and where it doesn’t.

Pre-seed and seed founders

A real iPhone app for investors and first users, instead of a deck and a mockup.

Non-technical founders

Senior engineers make the technical calls and explain them in plain words.

Subscription consumer apps

Health, fitness, habits and learning, where people pay on their iPhone.

AI-first products

Assistants, voice, summaries and recommendations built into the app itself.

Marketplaces and booking

The customer-facing iPhone side of a two-sided product, connected to your backend.

Founders outgrowing no-code

Rebuild a no-code MVP as a native Swift app you fully own.

Not the right fit

Android at launch: this offer is native iPhone. See React Native or Flutter for both platforms.
Games, 3D and AR-heavy experiences.
Certified compliance from day one, such as HIPAA or PCI audits.
Open-ended hourly work without a defined first release.

How we work

Six stages, one team.

FAQ

Questions, answered.

Straight answers about cost, timing, quality and ownership.

How much does it cost to build an iOS app?

The price is fixed for the agreed scope and set before work starts. You first get a free working prototype of the core flow in 1 day, then a fixed price and release date for the production version.

How long does it take to build an iOS app?

A working prototype takes 1 day. The production release date is agreed upfront and depends on the scope; AI speed with senior engineering makes it much faster than classic development.

Do you publish the app to the App Store?

Yes. We prepare the build, metadata and screenshots and submit the app for review. The review itself is on Apple’s side.

Do I need an Apple Developer account?

Yes. The Apple Developer Program is registered in your name, so the app is published under your company. We help you set it up on day one.

Can you add AI features like chat, voice or recommendations?

Yes. Assistants, summaries, voice input and personalised recommendations are built in when they are part of the agreed scope.

Is the prototype really free?

Yes, with no commitment. After a 30-minute call we build a working prototype of your core flow in 1 day, and then you decide whether to continue to the release.

Will the price go up during the build?

No. The price is fixed for the agreed scope. Anything new you want to add mid-build is priced separately and built only after you approve it.

Who owns the code?

You do, 100%. The source code, repository and accounts are yours, and the release ships to the App Store under your name.

Is AI-written code safe to ship to production?

It ships only after senior review. Senior engineers own the architecture, security and code quality, and automated tests run on every change.
