Questions
Mobile app development, quick questions
Yes. You can bring Kyan in for a defined project, such as an MVP or a new feature, or as a longer-term product partner. Either way you get a full team of app developers, designers and strategists rather than a lone contractor.
It depends on the complexity, the number of platforms and the features involved. Most projects start with a short discovery to scope the app and give you a clear, itemised estimate before any build begins, so there are no surprises. Prices are typically in the low to medium 10s of thousands but of course can vary for more complex apps or bespoke features.
A focused MVP can be in users’ hands in a few weeks, while larger products run longer. Modern AI tooling lets us prototype and iterate quickly, so you see something working early rather than waiting until the end. At a magnitude you can see a working product in perhaps 2 to 3 months.
Yes. Our app designers handle user research, journeys, interface design and prototyping, working alongside our developers so the app looks right, feels right and is built to last.
It depends on your goals. Native (Swift, Kotlin) is best when you need the highest performance or deep platform features. Cross-platform with React Native gives you one codebase across iOS and Android and a faster time to market and a little less cost. We help you choose based on your users and budget.
Yes. We build native iOS and Android apps and cross-platform apps with React Native, and design the interface to feel right at home on each platform.
Our app developers are UK-based, working from our London and Guildford studios, so you get a team in your timezone that you can meet in person.
Yes. We support your app post-launch, adding features, optimising performance and making sure it scales as your user base grows. Launch is the start of the relationship, not the end.
