Service · Mobile Apps

Mobile apps customers actually keep on their home screen.

Native-feeling iOS and Android apps engineered for real usage — offline-first, push-ready, and performant on the devices your customers actually own. React Native by default, Swift and Kotlin where the problem demands it.

Why most company apps get deleted

Most company apps don't fail because of design. They fail because they don't work on a slow network, crash on older phones, or push notifications nobody opens. The customer downloads, tries once, uninstalls.

We build mobile apps with the constraints that actually matter — battery, network, storage, App Store policy — baked in from day one. Offline-first sync, smart caching, and crash-free releases.

Whether it's a customer-facing product, an employee tool, or a clinical workflow, we ship apps people use more than once.

  3. 03

    Feature build (weeks 6–10)

    Two-week sprints. TestFlight / Play Console builds at the end of every sprint. Real users get hands-on by week 7.

  4. 04

    Hardening + submission

    Performance pass, crash-free target, store assets, privacy declarations, App Store and Play Store submission.

  5. 05

Frequently asked

React Native or native?+

React Native for 80% of business apps — same team ships iOS and Android, faster time-to-launch, almost no perceptible difference for users. Fully native when we're doing heavy device integration (Bluetooth, ARKit, HealthKit, complex camera work) or when extreme performance matters.

What about Flutter?+

We work in Flutter when the customer's team already maintains a Flutter codebase or when a specific UX requires it. Not our default — React Native has a deeper ecosystem and is easier to staff long-term.

How do you handle App Store rejections?+

We design around Apple's and Google's policies from day one — privacy declarations, sign-in policies, payment policies. When a rejection does happen, we typically resolve it in 1–2 review cycles.

Do you do design too?+

Yes — product design is part of every mobile engagement. We work with your design team if you have one, or supply our own designer when you don't.

Can you build the backend too?+

Yes. A typical mobile project includes a Next.js or Python backend, Postgres database, push services, and admin tooling alongside the iOS/Android apps.

What about ongoing maintenance?+

Mobile apps need ongoing care — OS updates twice a year, store policy changes, and feature evolution. We offer monthly retainers for post-launch maintenance with the same engineers who built it.
