# Reverb vs K7D

The clearest difference is ratings volume: K7D at 79 against Reverb's 14. K7D also leads on price ($3.99 vs $4.99). Reverb's advantage is review sentiment (89% vs 80%). On rating, update cadence, ads and in-app purchases there is nothing between them.

Reverb costs $4.99 and K7D $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

K7D holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: K7D has 79 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 89% of Reverb's written reviews are positive against 80% of K7D's, so the app with the better star average is not the one people write more warmly about.

Reverb ships an update every 4 months, K7D every 3 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
