Mobile app development.

We build iOS and Android apps for companies and start-ups. We work out the scope with you, prototype it in Figma, write the code and submit it to the App Store and Google Play, and we handle the updates after launch. If you are outside Turkey and want to outsource the work, the project runs remotely: video calls, test builds on your own phone and a written quote in euros.

Scope

What we build in mobile app projects

iOS and Android apps for phone and tablet. We also build the parts around them, such as notifications, subscriptions, offline mode and the admin panel, and we handle the App Store and Google Play submissions.

  • Native iOS & Android

    Apps written in Swift/SwiftUI and Kotlin/Jetpack Compose. You can use platform features such as widgets, Live Activities and Material 3 from day one.

  • Cross-platform

    One codebase for iOS and Android with Flutter or React Native. It usually takes less time than two separate native apps and costs less to maintain.

  • Backend & admin panel

    APIs, user management, a content panel and reports on Firebase, Supabase or Node.js.

  • Payments & subscriptions

    In-app purchases, subscriptions and ads, set up to follow Apple’s and Google’s payment rules.

  • Notifications

    Push notifications, scheduled reminders, deep links and in-app messaging.

  • App store optimisation

    We prepare the store screenshots, description and keywords, so the app is listed under the right terms in store search.

By the numbers

Toolbox

Technologies we use for mobile apps

  • Swift / SwiftUINative apps for iPhone and iPad. New iOS features such as widgets and Live Activities can be used on the day they ship.
  • Kotlin / Jetpack ComposeNative Android apps built with Google’s current UI toolkit and Material 3 components.
  • FlutterOne codebase for iOS and Android. On most projects it takes less time than building two separate native apps.
  • React NativeWritten in TypeScript, so it can share business logic with your web project. Screens are drawn with native components.
  • FirebaseFor sign-in, push notifications, analytics and crash reports. You don’t have to set up and run a server of your own.
  • SupabaseAn open-source backend built on Postgres, with user sign-in, file storage and row-level security.
  • FastlaneA release pipeline that automates builds, code signing and store uploads.
  • TestFlight / Play ConsoleClosed testing and staged rollouts, so problems show up before every user gets the update.

Roadmap

Mobile app development steps and timings

Before work starts, we tell you in writing what each step will deliver. Development runs in two-week sprints, and at the end of each one we send a working build to your test device. Nothing goes to the App Store or Google Play without your approval.

  1. Step 1:

    Discovery and scope

    Goals, users and the feature list; deciding between native and cross-platform.

    1–2 weeks
  2. Step 2:

    Design and prototype

    User flows and a clickable prototype in Figma.

    2–3 weeks
  3. Step 3:

    Development in sprints

    Two-week sprints, each ending with a working build on your test device.

    6–14 weeks
  4. Step 4:

    Testing and store launch

    Real-device testing, store assets, privacy forms and the review process.

    1–2 weeks
  5. Step 5:

    Maintenance and growth

    Updates for new iOS/Android versions, fixes and new features.

FAQ

Questions about mobile app development

Should I choose native or cross-platform?

We recommend native if the app needs heavy animation, deep access to hardware such as the camera and sensors, or platform-specific features. If you want to launch quickly and maintain one codebase, Flutter or React Native makes more sense. We decide together during analysis, based on the feature list.

How long does store approval take?

For typical submissions, Apple’s review takes about 1–3 days and Google Play’s 1–7 days. Newly created personal Google Play accounts may have to run an extra closed test first, and we plan the schedule around that.

Can you take over our existing app?

Yes. We first review the code and infrastructure and give you a written report on the risks and what needs fixing. Then we tell you whether we recommend maintaining it or rewriting it, and why.

How much does app development cost?

Cost depends mostly on the number of screens, the backend, payments and integrations. Our indicative ranges for 2026: a simple app or prototype costs about €5,000–15,000 and takes 6–10 weeks; an MVP for iOS and Android costs about €15,000–40,000 and takes 2–5 months; a full product with backend, admin panel and payments starts at €40,000 and takes 5–8 months. We give you a firm figure in a written quote after discovery.

What do the store accounts cost?

The Apple Developer Program costs USD 99 a year and Google Play Console a one-off USD 25, so about USD 124 in the first year. The stores take a commission on in-app sales (15% at Apple for small businesses). We recommend opening the accounts in your company’s name, and we help you set them up.
