Mobile apps

iOS and Android, one team, from idea to store.

We build mobile apps from tools for drivers to trackers for athletes — and we write them to be maintainable: one codebase for both platforms, tests where a failure would actually hurt, and shipping to the stores as part of the project rather than the client's problem.

In short

PB Devs builds iOS and Android apps from a single codebase — two engineers in Poznań, Poland, carrying a project from idea to store listing. Offline behaviour where the app needs it, App Store and Google Play submission handled by us, and a number that comes after a free call and a one-week prototype rather than off a price list.

What it covers

  • iOS and Android from a single codebase — not two teams and two invoices.
  • Offline-first behaviour and sync, when the app has to work without a signal.
  • App Store and Google Play submission, including everything that usually goes wrong there: signing, consents, policies.
  • The versions after launch, because the first one never is the last.

Where to check it

The questions that come up

More than a website, and the honest range is wide: an app with a login and a list is a different order of magnitude from one with payments, maps and offline sync. We give you a number after a free call and a prototype, so it rests on code we have already written rather than on a guess. Anyone quoting an app without asking you a single question is quoting a template.
