Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
OneControl Auto holds the better App Store score, 2.7 against 2.5. That said, the two scores are not equally well evidenced: OneControl Auto has 793 ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 21% of Audio2Ear's written reviews are positive against 6% of OneControl Auto's, so the app with the better star average is not the one people write more warmly about.
Audio2Ear ships an update every 11 months, OneControl Auto monthly. The most recent releases landed on October 6, 2026 and October 13, 2026 respectively.
