Screenshots
Download, reorder and add screenshots per language and device, checked against Apple's sizes.
Screenshots shows the screenshots already in App Store Connect, per language and per display type, in their App Store order.
Download
TakeOff downloads every screenshot to this Mac once and never fetches the same image twice. Show in Finder opens the folder.
Reorder
Drag a screenshot to a new place, or use its context menu: Move to Front, Left, Right or to End. The new order is a draft and is sent with the next push.
Add
Choose PNG or JPEG files, or drop them on the screen. TakeOff checks each image’s pixel size against Apple’s accepted sizes and puts it in the matching display type; an image of the wrong size is refused before anything is uploaded. A set holds at most 10 screenshots. The screenshot sizes guide lists every accepted size.
New screenshots are uploaded with the next push. If Apple fails to process an uploaded image, TakeOff removes it again so the set is not left with a broken image. Uploading screenshots is part of Pro; reordering is free.
