App development , App Store, Google Play and web
iOS and Android app development
Written with AI, reread by people, approved by stores.
A real app, published on your App Store and Google Play account, born from a single code base that also works on the web. Programming agents take us to the prototype in days; architecture, security, and auditor rules remain our job.
How we develop an app for iOS and Android
We write only one app with modern web technologies (Next.js, React, TypeScript) and bring it to iPhone and Android with Capacitor, plus a PWA version for the browser. AI accelerates prototype and development, we review every line and follow the app until approved on the App Store and Google Play.
- One base, three platforms
- iOS, Android and web from the same code: a function is written once and you find it everywhere.
- Native functions where needed
- Push notifications (APNs and FCMs), in-app purchases with StoreKit 2, camera, deep link. If a plugin does not exist, we write the native form.
- Prototype in days
- With programming agents like Claude Code the first prototype to touch comes in days, not weeks.
- Stores and properties
- We follow TestFlight, closed test and review. The app comes out on your developer account and the code remains yours.
AI-assisted app development, with every step covered
AI writes quickly. We take responsibility for every line.
We work every day with programming agents like Claude Code and Cursor. In a 2022 GitHub experiment programming with an AI assistant closed the same task 55% faster: it is not a promise on your project, it is the reason why today a prototype takes days.
What the agent does
- Drafts of screens and components
- Repetitive Code, Testing and Migration
- Variants to Compare in an Afternoon
- The documentation that nobody usually writes
What We Do
- Architecture and choices that cost money to change
- Code Review, Security, and Personal Data
- The App Store and Google Play Rules
- Decisions, made with you in Italian and not in jargon
Need AI features inside your app, or have a Lovable, Bolt or Cursor prototype to publish in the stores? See our page on artificial intelligence app development. For AI working across your business processes, see our AI Agents for Companies.
Mobile app development with Capacitor
One codebase, three platforms.
Capacitor, in plain English, is a native shell: it takes the web app and packs it as an iPhone and Android app, with access to notifications, camera, in-app purchases and phone files. The engine is one, the bodies are three.
You avoid paying twice for iOS and Android development: we write each feature once. When the wrapper cannot provide a function, we build the native part in Swift or Kotlin, as we did for Athleex's in-app purchases, managed through StoreKit 2 with a custom plugin.
export const theme = "light";
iPhone and iPad
- Publishing with App Store Connect
- Test versions with TestFlight
- Push Notifications with APNs
- Subscriptions and purchases with StoreKit 2
An honest clarification: every new version for iPhone and Android still passes from the review of the stores. We plan it with you, so it never comes by surprise.
From idea to app store
Custom app development, from idea to app store.
Six stages, no skips. The durations depend on your app; those that do not depend on us you find with the source.

Free Audit
Tell us your idea and who will use it. We identify the platforms, native features and review risks that matter. If you do not need an app, we tell you.
Days, not weeks
Prototype with AI
We use coding agents to build a clickable prototype for your phone. This is the right time to change direction: it costs little, and you can make decisions by trying the app.
Short cycles, with versions to try
Development
A working app built with Next.js, React and TypeScript, connected to your data, with notifications, in-app purchases, camera access and deep links. Every AI-written line receives human review.
TestFlight and closed test
Tests
On iPhone with TestFlight, on Android with Google Play closed test. Personal Google accounts created after November 13, 2023 must Keep at least 12 testers for 14 days before publishing: we put it on the calendar from the first day.
App Store and Google Play
Publication
Store tabs, screenshots, privacy, demo accounts for reviewers. Apple states that 90% of apps are reviewed in less than 24 hours; if a rejection comes, we can read it and answer it.
As long as the app lives
Growth and maintenance
New features, fixes, and requirements that change every year. Since April 28, 2026 Apple wants apps compiled with Xcode 26, from August 31, 2026 Google Play asks Android 16, i.e. API 36. We'll take care of it before it becomes a block.

How to choose
Native, cross‐platform or PWA: the honest table.
There is no best technology, there is the right one for your app. We start from the middle column; when a project asks for more, we tell you before signing.
| Criterion | NativeSwift for iOS, Kotlin for Android | Our starting pointCross-platformCapacitor (our base), React Native, Flutter | PWAWeb app installable from the browser |
|---|---|---|---|
| Bases of code | Two, one per operating system | One for iOS and Android; with Capacitor, it also supports the web | One, which runs in the browser |
| In Stores | Yes | Yes | No: installs from browser |
| Phone Functions | All, from the first day | Almost all through plugins; the rest requires a native module | Limited, especially on iPhone: Push notifications came with iOS 16.4 and only for the app added to the Home |
| Development cost | The highest: two apps to write and maintain | Lower than two native apps | The lowest |
| Updates | One version per store, each with its own revision | It is written once, then comes out as a new version in the two stores | Immediate, unreviewed |
| When it makes sense | Games, heavy 3D graphics, augmented reality | Most business and public apps | Internal tools, management software, a first test of the idea |

Proof: Athleex
A software house with an app that has passed Apple review.
Athleex is a platform for personal trainers: a business management web app, App Store and Google Play apps, and a PWA in six languages, from one codebase. We went through Apple's full review process, including rejections: demo accounts for reviewers (guideline 2.1), in-app purchases (3.1.1) and subscription terms (3.1.2).
We know what reviewers check because we have been through the process. When comparing app development agencies, ask each for an App Store link. A mockup has not passed app review.
- Guideline 2.1Completeness of the appRefusal: Reviewers need a demo account to join the appSolved: Dedicated demo account, with test data
- Guideline 3.1.1In-app purchasesRefusal: Subscription must go from Apple in-app purchasesSolved: StoreKit 2, with a native plugin written on purpose
- Guideline 3.1.2SubscriptionsRefusal: Subscription terms not clear enoughSolved: Duration, price, terms and privacy visible before purchase
The complete rules are in the Apple's App Review Guidelines.
Where do you start?
Each app starts with a different question.
This page is the map. The others go into detail: choose the one that most resembles your case.
Do you already have an app made with Lovable, Bolt or Cursor?
We bring it to production and to stores. And if you need AI inside the app (an assistant, document search, data read from a photo) you start from here.

Frequently asked questions
iOS and Android app development, the real questions.
The ones that make us call, usually before we talk about price.
It depends on functions, integrations and design: on the Italian market you go from a few thousand to hundreds of thousands of euros. With a single code base you pay for development once for two stores. Market segments, with sources, are on the cost page; our quote is at a fixed price, after the free audit.
For most business apps and for the public, cross-platform: just one code for iOS and Android, less cost and less time. The pure native serves for games, heavy 3D graphics or augmented reality. PWA is enough when the app is an internal tool and you don't need to be in stores.
The prototype to try on the phone comes in a few days; for the first published version you receive a calendar written after the audit. Then there are store times: Apple reviews most apps within a day, while a new personal Google account must first complete 14 days of closed testing.
It changes speed, not responsibility. Programming agents write prototypes, tests, and repetitive code in a fraction of the time; architecture, security, review, and store rules remain our jobs. The result is readable code, which any developer can pick up.
Yes: store cards, screenshots, privacy, TestFlight, closed test and review we follow them. The app comes out on your Apple and Google accounts, on behalf of your company; we work as invited contributors. If the account isn't there yet we'll help you open it, including the D-U-N-S number that Apple asks companies.
Yeah. The code is yours and is in a repository that you have access to; store accounts are in your name. If one day you want to change supplier or bring development into the house, take it all and go, without asking permission from anyone.
Yeah. An app never ends: every year Apple and Google raise the requirements and those who stay behind can no longer publish updates. We follow fixes, new system versions and new functions, with a clear maintenance agreement from the start.
Yes, but it is rarely convenient: with a code base only the second store costs little more. If your audience is almost everything on one system you start with that and the other you add later, without rewriting anything.
