Tag My Spool's advantage is rating (4.8 vs 4.0) and ratings volume (36 vs 1). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

OpenSpool is free to download; Tag My Spool costs $7.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Tag My Spool holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Tag My Spool has 36 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of OpenSpool's written reviews are positive against 92% of Tag My Spool's, so the app with the better star average is not the one people write more warmly about.
