Verdict
The clearest difference is rating: USTA Flex at 4.8 against ADIBO's 4.0. USTA Flex also leads on ratings volume (747 vs 1). ADIBO's advantage is review sentiment (50% vs 41%) and iOS requirement (10.0 vs 13.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
USTA Flex holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: USTA Flex has 747 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 41% of USTA Flex's written reviews are positive against 50% of ADIBO's, so the app with the better star average is not the one people write more warmly about.
USTA Flex ships an update fortnightly, ADIBO monthly. The most recent releases landed on October 21, 2026 and October 22, 2026 respectively.
