Service — Mobile

Mobile app development for products that have to survive the app store and the reviews.

We build mobile products end to end — architecture, interface, backend, store submission — for teams that need an app that holds up under real usage rather than a demo that works on one device.

We build mobile products end to end — architecture, interface, backend, store submission — for teams that need an app that holds up under real usage rather than a demo that works on one device.

For teams shipping their first app, or replacing one that is failing. Starting at $15,000. Typical timeline: 4–10 weeks.

What you get

  • iOS and Android builds from one maintained codebase where that fits
  • Backend, API, and data layer built alongside the app, not bolted on
  • Offline behaviour, push notifications, and deep links handled deliberately
  • App Store and Play Store submission, including the review back-and-forth
  • Crash reporting and analytics live from the first public build

How it works

Platform decision

Native or cross-platform is an engineering trade-off, not a preference. We make the call against your feature set, team, and budget, and explain the reasoning.

Build against real devices

Testing happens on physical hardware across screen sizes and OS versions throughout, not in a simulator until the week before launch.

Store submission

We handle listing assets, review responses, and rejections. First-time submissions get rejected for predictable reasons and we plan for them.

Post-launch watch

Crash rates and funnel drop-off get monitored through the first release cycle so early problems are caught while they are still small.

Frequently asked questions

How much does it cost to build a mobile app?

Mobile projects typically start around $15,000 and scale with platform count, backend complexity, and integrations like payments or real-time features. A focused single-platform MVP can come in lower; a multi-platform product with a custom backend runs higher.

Should I build native or cross-platform?

Cross-platform suits most products and roughly halves the cost of shipping to both stores. Native is the right call when you depend heavily on platform-specific hardware, background processing, or the last few percent of interface performance. We make the recommendation against your actual feature list.

Do you handle App Store and Play Store submission?

Yes, including listing assets, metadata, and the review process itself. First submissions are frequently rejected for predictable reasons — we plan the calendar around that instead of treating it as a surprise.

How long does mobile app development take?

Four to ten weeks depending on scope, plus store review time. Apple review is typically days, but a rejection resets the clock, which is why we submit with buffer rather than on the launch date.
