Favorite Apps: PastePal
I used to think the Copied clipboard manager for Apple devices was spiffy. I don't know how or why, but that app disappeared from the Internet and the App Stores.
PastePal seems to be its spiritual successor. It works perfectly, it syncs across devices, and the pro version is a one-time, reasonable $15 purchase. It's the only clipboard manager I've found that checks all those boxes.
