Sorry, "fix" (see copied below) does not survive sync to iTunes, so I am back to this app not working on my older iPod.
Most recent download update (to earlier version) fixed it on my iPod. Thanks.
Previously I posted: "Update fix for iOS 8 broke it for iPod Touch 3rd Generation iOS 5.1.1; crashes and will no longer open; was great, now not so much."
However, now fixed and great again.
