What's New in False Checker
2.1
April 21, 2026
What's New in 2.1 • New look — pro-cinema monitor aesthetic with a viewfinder frame, live exposure stats, and a redesigned IRE scope. • Tap-to-isolate — select any band on the IRE scope to see only those pixels in color; everything else drops to monochrome for instant, at-a-glance comparison. • Stop difference — tap two bands to get the stops between them and the light ratio, now computed on linear scene light for accurate readings. • Accurate exposure pipeline — proper sRGB → linear → Rec.709 conversion with Rec.709 luma weights for reliable IRE mapping. • Camera capture — shoot a frame directly in the app and see false color immediately. • Share and save — send the processed frame to any app, or save it to your library. • Pinch-to-zoom & hold-to-compare — inspect detail and compare against the original with a touch. • New app icon.
