Now on iPad. The grading suite is rebuilt for the big screen: curves and HSL side by side, larger colour wheels, and type that's finally easy to read. Crazy Film — a film camera in your pocket.

Everything is processed on your device — no internet, no uploads.

Native iPad support Crazy Film is now a real iPad app, not a stretched phone layout. Every panel has been rearranged for the larger screen. · Rebuilt grading suite — Curves and HSL now sit side by side, so there's no more switching back and forth. The curve is square with the channel buttons stacked along its edge, which makes control points far easier to drag. Colour wheels are bigger, with the RGB readouts moved out to the sides. · Larger type throughout — Interface text has been stepped up across the app, and it now follows your system Text Size setting. Parameter names, preset names and tab labels are all clearer. · Roomier panels — Export, frames, film-strip splitting, recipes and every other screen now open at a larger size on iPad, so there's far less scrolling. · Better strip splitting — Buttons, sliders and preview thumbnails are all larger, making offset and frame spacing much easier to fine-tune. Other improvements · Terms of Service and Privacy Policy now open full screen instead of resizing mid-load. · Avatar, handwritten signature and brand logo now use the in-app photo browser, which is faster and more reliable. · Fixed a number of text sizes that were too small to read comfortably.
