Mobile App Development
From MVP to millions of users — we design and engineer mobile apps that feel native, launch fast, and scale with your business.
Most mobile projects do not fail at the coding stage. They fail because the scope was never bounded, because the app was designed for a demo rather than a store listing, or because nobody owned performance until users started leaving one-star reviews. We structure engagements to remove those three failure modes before the first sprint starts. We build from India, and our working day overlaps the UK and European morning.
What you get
- Native iOS (Swift) and Android (Kotlin) when the product depends on platform capability — background processing, hardware access, deep OS integration, or the last ten percent of interface polish.
- Cross-platform with Flutter or React Native when a single team shipping to both stores matters more than platform-specific behaviour. We will tell you which of the two fits, and why, before you commit.
- Offline-first architecture and push notifications, so the app stays useful on a bad connection and re-syncs cleanly instead of losing state.
- App Store and Play Store submission handled end to end, including the review rejections that catch most first-time publishers — privacy manifests, data-safety declarations, account deletion requirements, and screenshots.
How we work on mobile
Mobile is the one platform where you cannot patch your way out of a bad launch. An app update takes hours to days to reach users, and the store listing carries your rating permanently. So we front-load the decisions that are expensive to reverse.
We open with a discovery sprint that produces three artefacts: a bounded scope for v1, a platform decision with the reasoning written down, and a performance budget — cold start time, frame rate targets, and bundle size ceilings — agreed before anyone writes a feature. That budget then goes into CI, so a regression fails the build rather than surfacing in a review.
Build runs in two-week cycles with a demo on a real device at the end of each one, not a simulator recording. From the first cycle onward there is an installable build on your phone. Store submission is treated as a workstream of its own, started weeks before launch rather than the Friday you hoped to ship.
After launch we instrument crash-free session rate, cold start, and funnel completion, and we stay on to act on what those numbers say.
Stack we work in
Swift, Kotlin, Flutter, React Native, Firebase. For backend we typically pair with our web and cloud practice rather than treating mobile as an island.
Who this is for
Founders taking a first product to store. Product teams whose existing app has outgrown the codebase it launched on. Companies with a working web product that now need a mobile surface without rebuilding the business logic twice.
What you receive
Source code in your repository from day one, the design file, the store listings, a performance baseline, and a written handover. No lock-in and no "managed" arrangement that makes leaving expensive.
Frequently asked questions
How long does it take to build a mobile app?
It depends less on engineering speed than on how many decisions are still open when the build starts.
Should I choose native or cross-platform?
Cross-platform if you are shipping the same product to both stores and your feature set is mostly screens, data, and networking. Native if you depend on hardware, background execution, or platform-specific interface behaviour. We make this call during discovery and write down the reasoning.
React Native or Flutter?
React Native if your team already lives in the React ecosystem and you want to share logic with a web product. Flutter if interface consistency across platforms matters more and you want fewer native bridges in the way.
Do you handle App Store and Play Store submission?
Yes, end to end, including the review rejections most teams hit on their first submission. We start the submission workstream weeks before launch.
What does a mobile app cost?
It depends on scope, platform count, and how much backend work sits behind the app. We return a tailored proposal within 48 hours of a scoping call rather than quoting a range that will not survive contact with your requirements.
