Set Math 3.0 is the biggest update yet. • All-new design. Every tool leads with one clear answer, and it stays visible above the keyboard while you type. • Night mode. Red on black for dark sets — pick it in Settings. • Film Footage. Running time, film needed and roll remaining for Super 8, 16mm, 35mm 2/3/4-perf, VistaVision, 65mm and IMAX. • Film gate sizes in Depth of Field, Hyperfocal, Field of View and Crop. • Six new tools: Flicker-Free Shutter, Anamorphic, Shot Size, Diopter, Battery Runtime and Power Load. • Drop-frame timecode for 29.97 and 59.94. • Home screen shows your recent tools with their last answers. Rearrange tools by long-pressing any of them. • Number pad now has a Done button, and tapping anywhere closes it. • Fixes: unit switching in EV and the unit converter now converts your values, 23.976 fps is no longer rounded, and more. Thanks to everyone who wrote in — keep it coming.
