# Stereo Delay vs K7D

The clearest difference is ratings volume: K7D at 79 against Stereo Delay's 5. K7D also leads on update cadence (every 3 months vs every 6 months). Stereo Delay's advantage is rating (4.8 vs 4.6) and chart position (#195 vs unranked). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

Stereo Delay costs $2.99 and K7D $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Stereo Delay holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: K7D has 79 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 75% of Stereo Delay'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.

Stereo Delay ships an update every 6 months, K7D every 3 months. The most recent releases landed on September 11, 2026 and September 22, 2026 respectively.
