iOS Work

Troughton-Smith first became involved with writing iPhone software shortly after its initial release, developing for the system with only a compiler and reverse-engineered header files. He would e-mail his creations to a friend with an iPhone who would run the application and send a screenshot back. His first application, Nuker, was developed this way.

He became well-known on his release of Stack, an implementation of Apple Inc.'s Stacks feature of Mac OS X v10.5 "Leopard". He is also responsible for the port of id Software's Doom game to iPhone, partnering with ZodTTD for distribution and development.
Troughton-Smith also built the Grace App For Autism which has 'democratised the availability of language aides' and is the winner of many accolades and awards.
