Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Mio holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Mio has 75 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 83% of Counter B's written reviews are positive against 51% of Mio's, so the app with the better star average is not the one people write more warmly about.
Counter B ships an update every 3 weeks, Mio monthly. The most recent releases landed on November 10, 2026 and November 1, 2026 respectively.
