Back-ends, APIs and admin dashboards
The part users never see: accounts, payments, content, notifications and the dashboards your team runs the app from.
Most apps are only as good as the system behind them. Festival lineups change during the day, tickets have to be valid at the gate, payments have to reconcile. We build back-ends and integrations that keep the app and your business in sync.
We pick the simplest setup that does the job, from managed services like Firebase for a fast start to custom APIs on your own cloud when you need full control.

How much does an app cost?
It depends on what the app needs to do: the number of screens and features, whether it needs a back-end, payments or integrations, and how polished the design should be. After a short discovery call we send a clear estimate for a first version. Starting with a focused first version and growing it from real use is usually the best value.
How long does it take to build an app?
A focused first version can launch within weeks; larger platforms with back-ends and integrations take a few months. After discovery you get a timeline with milestones and working builds along the way, so you're never waiting in the dark.
Flutter or native: which should I choose?
For most apps, Flutter is the best value: one codebase for iPhone and Android, with native performance and one team to pay. Native Swift or Kotlin is better when an app leans heavily on the newest platform features or deep hardware access. We've done both since 2008 and recommend what fits your project.
