Mobile apps that pass every check

iOS and Android apps built to behave dependably on real phones, in real conditions, and to pass store review smoothly.

Approach

We usually build with a cross-platform framework so one codebase serves both platforms, keeping maintenance predictable. Where an app depends on demanding hardware features we recommend native modules, and explain the cost and maintenance implications in writing.

Included as standard

  • Prototype of core journeys on your own phone early in the project.
  • Sign-in, account management and in-app account deletion where stores require it.
  • Offline-tolerant data handling and clear connection states.
  • Push notifications with considered permission prompts.
  • Accessibility: VoiceOver, TalkBack, dynamic type and contrast.
  • Testing across a range of physical devices and OS versions.
