One Peak

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.

01

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.

01A clear mobile-first user journey
02Auth, onboarding, and account state that persist correctly
03Backend APIs, storage, and permissions around the app
04Analytics and release planning for iOS and Android

02

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.

01Choosing native or cross-platform without a product reason
02Skipping offline, upload, or sync edge cases
03Leaving App Store and Play Store constraints until launch
04Building AI features without clear user control or data boundaries

03

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.

01Cross-platform or native decision based on product constraints
02Core mobile flow and state model
03API, storage, auth, and AI integration boundaries
04Release 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.

01From €7,000 — iOS and Android from one codebase
02+€2,000 for UI/UX design and branding
03App Store and Play Store submission handled for you
04TestFlight in 4–6 weeks, store release in 6–8

05

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.

01Documented codebase in your repository
02Backend, push notifications, and store listings under your accounts
03Crash reporting and product analytics wired from day one
04A release pipeline your next developer can run

Frequently asked questions

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.
