Bloom costs $3.99 and KotoTunings $8.99 up front. Neither carries in-app purchases, so what you see is what you pay.
KotoTunings holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Bloom has 99 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 84% of Bloom's written reviews are positive against 56% of KotoTunings's, so the app with the better star average is not the one people write more warmly about.
Bloom ships an update every 11 months, KotoTunings every 5 months. The most recent releases landed on October 31, 2026 and October 9, 2026 respectively.
