Developer and publisher, under one roof

We don't only write code. We ship and run real products, so we understand what it takes to get an app approved, discovered and kept healthy after launch.

  • App Store and Google Play submission, review and policy compliance
  • Privacy-first engineering aligned with UK GDPR and EU GDPR
  • Clear, fixed-scope proposals and transparent communication
