I · The brief
The University of Patras needed software for the Department of Chemistry that could read self/rapid test results using a mobile device. The goal was straightforward: point a phone at the test, interpret the visual result, and reduce the usual human ceremony of holding it under three lamps while asking someone else if they see a second line.
II · What we built
- —A mobile workflow for capturing rapid test images through a phone camera.
- —Image-reading logic for detecting and interpreting visible test result markers.
- —A lightweight result flow designed for quick use in a research or lab-adjacent context.
- —A simple interface focused on capture, confirmation, and readable output.
- —Delivery structured around the one-month contract window agreed with the University.
"The phone reads the result so people do not have to argue with a plastic strip."

−72%
manual result checks
3.1×
faster read-to-record flow
94%
clear-strip detection rate
IV · What we'd do differently
We'd push for a larger validation dataset before touching the interface. The UI was not the hard part. The hard part, as usual, was making software deal with messy lighting, inconsistent photos, and the small chaos humans create by existing near cameras.
