Photograph UK post boxes and royal cyphers to learn their local history
Point your iPhone at a post box or piece of street furniture and let the app identify the object in front of you.
Learn which monarch each cypher represents and what it tells you about the age and origin of the item.
Get explanations of shapes, lettering and manufacturing details that make UK street furniture distinctive.
A lightweight interface designed to be used outdoors while walking, with clear onboarding and instructions.

AI spatial-audio companion that helps blind and low-vision users explore indoor spaces
Directional sound cues are positioned around the listener so the location of nearby objects and obstacles is conveyed through hearing rather than sight.
Ask spoken questions about your surroundings and receive AI-generated descriptions, such as what items are placed on a table or counter.
Depth sensing plus AI helps identify and locate objects and explore paths around indoor obstacles, with the caveat that this remains an experimental capability.
Control the app and ask questions hands-free by speaking to Siri, so the phone does not need to be handled during use.
