Mobile app development company UK
iOS & Android, one team.
Building separate iOS and Android apps doubles the cost and halves the speed. We build native-quality apps from a single modern codebase — the same polish your users expect from the apps they already love, shipped to both stores together.
Mobile app development problems we fix.
Two native apps means double the cost, double the timeline.
We build both platforms from one modern codebase — native-feeling, but far faster and cheaper to ship and maintain.
Cross-platform apps you've seen feel cheap and laggy.
We obsess over the details — gestures, transitions, native feel — so users can't tell it isn't fully native.
The App Store process is a black box and you've been burned before.
We handle submission, review and launch end to end, and set you up for the ratings that keep you ranked.

Mobile app development questions, answered.
How much does it cost to build a mobile app?
Mobile apps at Softgen start from £30,000 for both iOS and Android. We give you a fixed price and timeline after scoping — the feature set drives the number.
Do you build native or cross-platform?
We build cross-platform with React Native and Expo, which gives native-quality results from one codebase — far faster and cheaper than two native builds, where native is needed we'll tell you.
Do you handle App Store and Play Store submission?
Yes — we handle the entire submission and review process and support you through launch and the first releases.
