# Slyder vs azooKey

The clearest difference is in-app purchases: azooKey at none against Slyder's 10. Slyder's advantage is ratings volume (1.6K vs 5) and rating (4.5 vs 4.2). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Slyder sells 10 in-app purchases, starting at $0.99 per month. azooKey asks for nothing beyond the download.

Slyder holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Slyder has 1.6K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 69% of Slyder's written reviews are positive against 71% of azooKey's, so the app with the better star average is not the one people write more warmly about.

Slyder ships an update every 10 days, azooKey every 3 weeks. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
