KnotweedID Live on the App Store
Spot Japanese knotweed before it costs you thousands.
The UK's friendliest way to identify Japanese knotweed: instant camera identification, expert guidance through every season, and surveyor-verified reports when it really matters.

What it is
Japanese knotweed can knock five figures off a property's value and turn a straightforward sale into a stand-off. KnotweedID exists so you know what you're looking at in seconds, not weeks: point the camera, get an answer, and see exactly what to do next.
Behind the camera is an identification engine tuned for UK gardens and verges, backed by seasonal guides that show what knotweed actually looks like in January as well as June. And when a mortgage, sale or dispute needs more than an app's opinion, a real UK surveyor reviews your photos and issues a formal report.
