Mobile apps for iOS & Android.
Flutter, React Native, and native builds — from MVP prototype to App Store launch to post-launch iteration.
Mobile App Development, done right.
A mobile app is a much larger commitment than a website. App Store review, device fragmentation, offline behaviour, push notifications, in-app purchases, and long-term platform maintenance are all realities you inherit the day you ship.
We build cross-platform apps for consumer products, internal ops tools, and B2B SaaS extensions. We choose Flutter when a single codebase and consistent UI matter, React Native when the client already has React expertise, and native (Swift/Kotlin) when platform-specific integration or performance demands it.
Scope of work.

How we work.
Product & platform discovery
One-week discovery: user flows, platform choice (Flutter vs RN vs native), backend architecture, timeline, and monetisation model.
Design & prototype
Interactive Figma prototype covering all core user journeys. Tested on real devices before code is written.
Build in sprints
2-week sprints with a real-device build at the end of each. TestFlight + Play Console internal testing throughout.
Launch & post-launch
App Store + Play Store submission (we handle it). Post-launch: monitoring, crash reporting, iteration based on real usage data.
Real projects, this discipline.
