Mobile App Development

Mobile app development for serious startup products.

One Peak builds mobile apps that connect polished user experiences with the backend, AI tools, auth, analytics, and operational workflows needed to launch and iterate.

What mobile app founders usually need first

The first release should prove the core mobile workflow while keeping the technical foundation clean enough for iteration.

  • A clear mobile-first user journey
  • Auth, onboarding, and account state that persist correctly
  • Backend APIs, storage, and permissions around the app
  • Analytics and release planning for iOS and Android

Common mobile app mistakes

Mobile builds get expensive when teams treat the app as only screens and defer the hard product, data, and release decisions.

  • Choosing native or cross-platform without a product reason
  • Skipping offline, upload, or sync edge cases
  • Leaving App Store and Play Store constraints until launch
  • Building AI features without clear user control or data boundaries

What we would prioritize first

We would scope the first mobile version around the primary user loop, the right build approach, and the backend services the app depends on.

  • Cross-platform or native decision based on product constraints
  • Core mobile flow and state model
  • API, storage, auth, and AI integration boundaries
  • Release checklist, analytics, and post-launch roadmap

What it costs and how long it takes

Mobile MVPs start at €7,000 for two core features on a cross-platform codebase, including app store setup, cloud backend, and 30 days of post-launch support. Most apps go from kickoff to TestFlight in 4–6 weeks and to store release in 6–8.

  • From €7,000 — iOS and Android from one codebase
  • +€2,000 for UI/UX design and branding
  • App Store and Play Store submission handled for you
  • TestFlight in 4–6 weeks, store release in 6–8

What you get at handoff

A store-ready app you own end to end, with the backend, analytics, and release pipeline set up to survive iteration.

  • Documented codebase in your repository
  • Backend, push notifications, and store listings under your accounts
  • Crash reporting and product analytics wired from day one
  • A release pipeline your next developer can run

Practical answers

Questions founders ask before moving forward.

How much does it cost to work with One Peak?

MVP development starts at €7,000 for two core product features, with login, security, architecture, deployment, and 30 days of post-launch support included. UI/UX design and branding adds €2,000, and products with three or more features get a custom quote.

Who owns the code and accounts?

You do, from day one. The repository, cloud accounts, app store listings, and analytics all live under your ownership — there is no lock-in if you later hire in-house or switch teams.

What happens after launch?

Every build includes a 30-day post-launch window: we monitor errors and analytics, fix issues, and turn the first real usage into a prioritized iteration roadmap before handing over or continuing.

Do you publish the app under our developer accounts?

Yes. We set up or use your Apple and Google developer accounts so ownership, reviews, and revenue stay with you.

Should a startup build cross-platform or native?

Cross-platform is often the right first choice when speed and shared product logic matter. Native is better when platform-specific performance, hardware, AR, capture, or OS-level behavior is central to the product.

Can One Peak build the mobile app and backend together?

Yes. The strongest mobile products usually need app, backend, auth, storage, analytics, and operational tooling designed together.
