ReceptionRating · Positive reviews · Number of ratings

Left Pocket Poker Tracker holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: Left Pocket Poker Tracker has 115 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of 21 Card Counter's written reviews are positive against 85% of Left Pocket Poker Tracker's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

21 Card Counter ships an update fortnightly, Left Pocket Poker Tracker weekly. Both last shipped on November 3, 2026.
