Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
AudioKey 2 holds the better App Store score, 5.0 against 2.1. That said, the two scores are not equally well evidenced: Baha Smart App has 86 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 16% of Baha Smart App's written reviews are positive against 11% of AudioKey 2's, so the app with the better star average is not the one people write more warmly about.
Baha Smart App ships an update every 3 months, AudioKey 2 every 4 months. The most recent releases landed on October 17, 2026 and July 7, 2026 respectively.
