NameSake's “What Do You Want to Change?” sheet, showing Whole Name, Beginning, End, and Beginning and End options.

Change the whole name, or just the ends.

Pick Whole Name, Beginning, End, or Beginning and End — NameSake only ever touches the part you tell it to.

NameSake's sequence numbering rules, with a live preview of eight renamed files.

Names and numbers, exactly your way.

Set your rules and watch the preview update instantly — every new name shown next to the one it's replacing, before anything changes.

NameSake's start screen after a rename, with an Undo option in the Recent list and in a confirmation toast.

Changed your mind? Undo, even later.

Every rename can be undone — right after running it, or later from Recent, even after closing the app entirely.

Nothing leaves your device.
