Questions
Before you ask
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.
Do you also build the back-end and admin panel?
Yes. We build the APIs, accounts, payments, notifications and the admin dashboard your team uses to run the app, or connect the app to systems you already have.
