One codebase, three destinations
A single app that ships to iPhone, Android and, when it fits, the web. You maintain one app, not three versions that drift apart.

Apps for iOS and Android, actually published
An app is not finished when it works on your phone. It is finished when it is on the App Store and Google Play, passes the reviews, gets updated without breaking anything and people use it. That is where most projects get stuck.
At InfinyAI we build mobile apps for businesses and take them all the way to the store: one codebase for iPhone, Android and the web, with the listing, screenshots and privacy declarations ready to pass review.
We are a verified organization in the Apple Developer Program and on Google Play Developer, and members of the Microsoft AI Cloud Partner Program. Operating base in Bilbao; projects in Spain and internationally.

Scope and price agreed before we start
Scope
What we do and how far we go
We do not hand over the code and disappear. We stay until the app is in the store and can be maintained.
Publishing in the stores
Listing, screenshots, copy, privacy policy, data declarations and answers to the reviewer. The part nobody sees that decides whether you get published or not.
Updates without waiting for the store
Anything that does not touch native code is published remotely and reaches the phone the same day. Native changes go through review, as they should.
Artificial intelligence inside the app
Text or voice assistants that read and change real data in the app, when they solve something specific.

Who it is for
This page is for you if...
- You need an app for your business and want it to reach the stores, not stay a demo.
- You have a website or a system and want a mobile version without rebuilding everything.
- A submission was rejected, or you have a project stuck before publication.
- You want to put AI inside the app, not just show a nice screen.
It is not a fit if you want to publish an app with no content and no maintenance: the stores reject that, and rightly so.
How we work
Clear from the first step
You tell us what the app is for
What it has to solve, who will use it and whether it goes to one store, both, or stays inside your company.
We define a realistic solution
Screens, integrations, stores, scope, timeline and price before development.
We build, publish and test
Development, submission for review, fixing whatever they point out and testing on real phones.

The app does not work alone
An app usually needs a website to present it, an assistant to serve users and processes behind it that are not done by hand.
Frequently asked questions
What you ask us
Do you build the app for iOS and Android at the same time?
Yes. We work with a single codebase that ships to iPhone and Android, and to the web too when it fits. That is what lets you maintain one app instead of three.
Do you take care of publishing it on the App Store and Google Play?
Yes, the store submission is part of the job: listing, screenshots, privacy policy, data declarations and the answers to the reviewer. That is where most submissions get stuck.
What happens if Apple or Google reject the app?
It is normal and it gets handled: we fix what they point out and submit again. We have been through it with our own apps, so we know what to check before sending it.
Can the app be updated without going through the store every time?
Many changes, yes: those that do not touch native code can be published remotely and reach the phone without waiting for a review. Anything that touches the native part does go through the store.
Can you put artificial intelligence inside the app?
Yes. FitCoachLab includes an assistant that reads and changes the plans by text or by voice. We propose AI when it solves something specific, not just to have it.
Have you published real apps or only prototypes?
Published and downloadable. FitCoachLab is on the App Store and Google Play, and Hamarka has been on the App Store since September 16, 2026, with Google Play pending approval.
How long does an app take?
It depends on the screens, the integrations and whether it has to be published in both stores. The timeline is set in the realistic-solution phase, before development.
