How we approach it

Mobile Apps

Most people delete an app within a week. The ones that survive do one job clearly, open fast, and still work when the signal drops. That is the bar we build to.

We ship cross-platform apps in Flutter and React Native, which means one codebase, two stores and a smaller maintenance bill than separate native teams. When a feature genuinely needs platform code — background audio, deep hardware access — we drop into Kotlin or Swift for that piece.

Our portfolio includes a published Android app on Google Play and a real-estate CRM used daily by field teams on both platforms.

What we deliver

Inside the engagement

A typical scope for this service. Yours will be narrower — that is the point of a written scope.

Flutter development

One Dart codebase for Android and iOS, with native-feeling transitions and a shared design language across screens.

React Native development

A good fit when your team already writes React and you want to reuse web logic, components and hiring.

Offline-first architecture

Local storage, sync queues and conflict handling so field teams keep working in basements and villages.

Push notifications

Transactional and campaign messaging via Firebase, with topic targeting, deep links and quiet hours.

Store submission & release

Play Console and App Store Connect setup, screenshots, privacy declarations and staged rollouts.

Post-launch support

OS-version updates, crash triage, performance work and new features on a monthly retainer.

Proof, not adjectives

Where this shipped

Real projects with real screenshots, the challenge, the stack and the outcome.

Questions, answered

Before you hire us

The questions we get most often about this work. If yours is not here, email and we will answer personally.

Flutter gives more consistent UI across platforms and excellent performance for animation-heavy apps. React Native is easier to staff if your team already knows React and shares code with a web product. We will recommend one after looking at your screens and your team, not by default.

Kaboom!
