Screens, navigation and the phone features your product needs, built once for both platforms.
- Push notifications
- Offline mode where it matters
- Camera, location, files
Mobile app development
AI mobile app development for iOS and Android, from one codebase
AI mobile app development means one team builds your iOS and Android app from a single codebase, with AI coding tools speeding up the screens and engineers reviewing and testing every change. We work with React Native and Expo or with Flutter, and we handle App Store and Google Play submission. Below you will find how to tell whether you need a mobile app at all, how we choose the framework and what the stores will ask of you.
- iOS and Android together
- Store submission handled
- Full code ownership
First question
Do you need a mobile app, or is a web app enough?
A mobile app costs more to build and to keep current than a web app, so it should earn its place. Check your product against both lists.
Choose a mobile app when
- People will use it many times a day, away from a desk.
- It needs the camera, background location, Bluetooth or offline work.
- Push notifications are central to how the product works.
- Your users expect to find it in the App Store or Google Play.
A web app is enough when
- It is used mostly at a desk or only now and then.
- You are still testing whether anyone wants the product.
- Your content must be found through Google.
- You want to release changes daily without store review.
If the second list fits better, look at AI web app development first. A mobile app can be added later on the same backend.
Framework
React Native or Flutter? How we choose
Both let one team ship to iOS and Android from a single codebase. The right one depends on your product and your team, not on fashion.
| React Native with Expo | Flutter | |
|---|---|---|
| Language | TypeScript and React, the same as our web stack | Dart |
| Recommended setup | The React Native documentation recommends building new apps with a framework and names Expo | Flutter's own tooling |
| Interface | Built from React components | Flutter has its own implementation of each UI control instead of using the system's |
| Sharing with a web app | Logic and developer skills carry over from a React web app | A separate language from the web app |
| We choose it when | You have or plan a React web app, or want one team for both | The design is highly custom and must look identical on both platforms, or your team already works in Dart |
Either way, you get one codebase in your repository, and we test on real iPhones and Android phones before release.
Store checklist
What the App Store and Google Play require before launch
Most first rejections come from the same handful of rules. Plan for them from the first week and review is rarely a surprise. Each item links to the rule itself.
Get a free project estimate in 24h- Apple: submit a finished app, with a demo account.The App Review Guidelines (2.1) ask for final versions without placeholder content, and demo account details if the app has a login.
- Apple: be more than a wrapped website.Guideline 4.2 says an app should go beyond a repackaged website and offer real usefulness.
- Apple: let users delete their account in the app.Guideline 5.1.1(v): if the app supports account creation, it must also offer account deletion inside the app.
- Apple: link your privacy policy.Guideline 5.1.1(i) requires the link in the store listing and inside the app.
- Apple: sell digital features through in-app purchase.Guideline 3.1.1 covers unlocking features or content inside the app.
- Google: complete the Data safety form.It is required for every published app, including apps that collect no data.
- Google: new personal accounts must run a closed test first.Personal developer accounts created after 13 November 2023 need at least 12 testers opted in for 14 continuous days before production access. Choose your account type early.
What is included
What a mobile app build covers
An app is three pieces of work, not one. All three are in the scope and the estimate.
The backend
Login, data and the API the app talks to. It can be shared with a web app or an admin panel. See our backend development services.
- Accounts and access rules
- Database and file storage
- Payments and integrations
The release
Getting through review and into the stores, then keeping the app current.
- Store listings and screenshots
- Test builds for your team
- Submission and review replies
How long a mobile app takes
A focused first version with one mobile app sits at the upper end of our 2 to 6 week MVP range. Larger products usually take 6 to 12 weeks. Store review and Google's testing period come on top and are outside our control. These add the most time:
- Offline use. Keeping data in sync after a connection returns is real engineering.
- In-app purchases. Each store has its own rules, test tools and review steps.
- Device features. Bluetooth, background location and video each need testing on real hardware.
- Tablet layouts. Supporting large screens well is extra design and testing.
- No existing backend. If the API has to be built too, it is part of the same timeline.
When we are not the right fit
- Games and 3D. They need a game engine and a different kind of team.
- Apps that live deep in one platform, such as watch apps or heavy augmented reality. A native specialist will serve you better.
- A wrapper around your existing website. Apple may reject it, and improving the web app is usually the better investment.
- An internal tool for a handful of staff. A web app avoids the stores entirely and costs less to maintain.
FAQ
Questions about AI mobile app development
Do I need my own Apple and Google developer accounts?
Yes. We publish under your accounts so that the store listings, reviews and revenue belong to you. We guide you through registration and you add us as developers.
How long does app store review take?
It varies and neither we nor you control it, so we do not promise a date. We send test builds early and check the store rules from the first week, which removes the usual reasons for rejection.
Can one codebase really cover both iOS and Android?
For most apps, yes. Screens and logic are shared, and a small amount of platform-specific code handles things like permissions. We test on real devices of both kinds before every release.
Will the app work offline?
It can, if that is designed in from the start. Offline use adds work, so in the scope we decide together which actions must work without a connection and which can wait.
Can the mobile app share a backend with my web app?
Yes, and it should. One API serves the web app, the mobile app and any admin panel, so the rules and the data are the same everywhere.
Who updates the app after launch?
We can, or your own team can with the documentation we hand over. Plan for some upkeep each year, because new iOS and Android versions need checking even if your features do not change.
