Setclock is free to use. If it helps you get gig-ready, you can buy me a coffee.
Choose how many sets you’ll play and the target length of each.
Items from removed sets will move into the last remaining set, keeping their order. No songs will be deleted.
On iPhone, tap Share / Save to Files, then choose Save to Files in the share sheet. Keep the backup to import your show later.
Copy this backup into a plain text file ending in .json. Import that file to restore it.
