GhostLab: GridSight

GridSight lays a grid of dots over your room and logs a break whenever something interrupts it. Stand the phone up, tap Start monitoring, and hold it still while the grid settles. From then on the app watches each spot on the grid. When something crosses one, it logs the time, the cell, and how strong the change was. TWO WAYS TO WATCH Virtual grid draws the dots over the camera, with no equipment. Watch physical grid follows the dots from a real laser grid projector and logs a break when one goes dark. A RECORD OF EVERY BREAK Each break can save four photos, in natural, negative, thermal-style and night vision colour, and a 10 second clip that starts 2 seconds before the break. The thermal and night vision looks are colour effects on the normal camera picture. They are not infrared. MADE FOR A DARK ROOM Dim the screen while monitoring so its glow stays out of the room. A soft tick can mark each break. Tune the grid density and the sensitivity to fit the space. YOUR DATA STAYS ON YOUR PHONE No account, no ads, no analytics. Photos, clips and logs stay on your device until you share them. TRY IT FREE, BUY IT ONCE Free to download, with a 48-hour free trial of every feature. After the trial, starting monitoring needs a one-time unlock of $4.99. No subscription, nothing renews. Your saved sessions and trips stay on your phone either way. HONEST ABOUT WHAT IT IS GridSight measures changes in light across the grid. It records what the camera saw, not what caused it. Dust, insects, shadows and passing headlights can all break the grid. You decide what it means. For entertainment and curiosity.
