Tune and quiet your 3D printer from your watch. Resonance scans find vibration frequencies, noise scans find your loudest speeds, and a step-by-step guide walks you through fixing them.
Learn more →FlockWatch
Know when ALPR cameras are near. A radar view of mapped license-plate cameras around you, with proximity alerts on your wrist. Free, built on OpenStreetMap data.
