The world's first health app could monitor people's glucose levels without breaking the skin - a development which has been described as the "holy grail" in diabetes care.
The Epic app could also help people find out if they could develop diabetes and need to make lifestyle changes to avoid it becoming a reality.
Users will only have to place one fingertip over the camera lens of their smartphone, the London-based firm has stated.
A series of close-up images are taken which accurately show information about the user's blood flow.
These are then sent to the cloud for analysis and can provide feedback on all kinds of vital information - from heart rate to temperature to blood pressure. It can also tell people about their respiration and blood oxygen saturation.
Developers say the app will be available to download - free of charge - on Android and iOS at the end of this year.
Almost all pre-existing glucose monitoring equipment is invasive - and many companies including Apple have talked of trying to develop a non-invasive method of testing.
