Questions Cardiff businesses ask us
Straight answers, real numbers. Anything else — ask on a 30-minute call and you'll have a written proposal within five working days.
How much does app development cost in Cardiff?
Most full mobile apps run from £15,000 to £60,000 depending on scope, built over 8 to 14 weeks. We scope the smallest launchable version first and agree a fixed price up front after a 30-minute call, so you decide with a real number in front of you.
Do you build native Android or cross-platform apps?
Both. Native Android in Kotlin and Jetpack Compose where performance and platform features matter, or React Native and Expo when one codebase for Android and iOS fits better. We recommend the cheaper route that still fits your product, and explain why in the proposal.
Do you work with Cardiff businesses remotely?
Yes — we're a remote-first UK studio working with clients across Wales and the rest of the UK. You watch progress on a private preview link with weekly demos, and we're happy to meet in person when it helps.
Who owns the app and the code?
You do. The code lives in a repository you own, the store listings and backend accounts are registered to your business, and you can walk away with everything at any point.
What happens after launch?
We can hand the app over, or keep operating it on a monthly retainer covering hosting, monitoring, security patching and a feature increment each month. Retainers start at £20/month.
