Put CullTone on your Mac

Pop in the card, or point it at a folder. CullTone Desktop copies and checks every file, sorts the wedding and starts the edits while you're still unpacking the camera bag, and it carries on happily on a flight with no wifi.

Get the app on your phone

On a phone or tablet, CullTone is for swipe culling, checking edits in the Review step and sharing galleries. It installs from the browser, with no app store: open CullTone on the phone and add it to the Home screen.

Will it run on mine?

Any Mac with Apple silicon runs CullTone. More cores and memory get through a big shoot sooner, and every Mac gives you the same cull, the same edits and the same gallery.

Sony ARW files are the best supported in the beta. Canon, Nikon and Fujifilm RAW files and DNG open the same way; keep your usual workflow alongside while you try them.
