ENG / APP

Apps that work where your people actually are.

iOS and Android apps for customers and field teams, designed for small screens, busy hands and patchy signal, and built to stay fast as they grow.

Try it: offline mode

No signal? Nothing gets lost.

Switch the phone’s signal off, record a few visits, then switch it back on. This is how our field apps behave.

Records are saved on the phone first, then sent to the server whenever there’s a connection.

      Cross-platform or native?

      The honest trade-off, side by side.

      Most business apps don’t need two separate codebases. Some do. Flip the switch to compare.

      CodebaseOne codebase for iOS and AndroidSeparate apps for iOS and Android
      Time to first releaseFaster: build once, ship twiceLonger: two apps to build and test
      PerformanceSmooth for forms, lists and dashboardsBest for heavy graphics and animation
      Device featuresCamera, GPS, offline storage, notificationsEverything, including the newest OS features
      Best forMost customer, business and field appsGames, AR, deep hardware integration
      We useReact Native, FlutterSwift, Kotlin

      Our usual recommendation for business and field apps.Worth it when the app lives or dies on device performance.

      04 / Anatomy of an app

      More than what’s on the screen.

      1. InterfaceThe screens people touch, designed for one hand and a quick glance.
      2. App logicValidation, rules and workflows that run on the phone itself.
      3. Storage on the phoneWhere data waits safely when there’s no signal.
      4. APIThe secure bridge between phones and your systems.
      5. Admin panel & databaseWhere your team manages users, content and reports.

      Road to the app stores

      From prototype to people’s phones.

      The path every app takes with us, and what you’ll be doing at each step.

      Step 1Clickable prototype

      Tap through the main screens on your own phone before we build.

      Step 2Beta testing

      Real users try test builds through TestFlight and Play internal testing.

      Step 3Store review

      We prepare the listings, screenshots and policies, and handle submission.

      Step 4Live

      Available on the App Store and Google Play, with crash reporting switched on.

      Step 5Updates

      Regular releases with fixes, improvements and new OS support.

      Tools & technology

      Native feel, practical tooling.

      Cross-platform frameworks where they fit, native code where performance or hardware demands it.

      FAQ

      Common questions.

      Something else on your mind? Ask us directly. A real person will reply.

      Ask a question
      Do we need separate apps for iOS and Android?

      Usually not. Cross-platform frameworks let one codebase serve both, which saves time and cost. We go native when the app needs it.

      Can the app work without internet?

      Yes. We build offline-first apps that save data on the phone and sync automatically once a connection is back.

      Will you publish it to the app stores?

      Yes. We prepare the listing and handle submission to the App Store and Google Play.

      Can we change forms without releasing a new version?

      Yes. Forms, questions and rules can be managed from the backend, so updates reach users without an app-store release.

      Do you support the app after launch?

      Yes. We monitor crashes and usage, release updates and keep it compatible with new OS versions.
