PewPewBug
Computer vision spots a mosquito on your camera and aims a (virtual) laser right at it — so you can find it and swat it.
Runs entirely on your device — no video is uploaded. Just for fun.
Tap or click the video to set a manual target; use Clear target to release it (on a computer you can also double-click to clear). To test detection: toggle the Demo bug, or wave a pen tip / toss a small paper ball in view. People and other large moving objects are ignored; a snapshot is captured automatically when bug confidence exceeds 99%. On a Mac, disable Center Stage in Control Center for the widest field of view.
