About Abdev

One Company,
Two Passions

Abdev — short for Abson Developments Ltd — is a UK-based iOS studio with over 15 years living and breathing the Apple ecosystem. We do two things: we deliver professional, high-quality iOS development for some of the UK's biggest businesses; and we create our own original games under the Secret Box label.

Whether that's helping a Sky News journalist break a story, letting a First Direct customer check their balance, or putting a pizza-delivery runner in a 10-year-old's hands — every line of code is written with the same care.
