# Surge vs Knottled

The clearest difference is in-app purchases: Knottled at none against Surge's 10. Knottled also leads on ads (none vs shown) and update cadence (every 10 days vs every 3 weeks). Surge's advantage is ratings volume (5 vs 1) and iOS requirement (15.6 vs 17.6). On price, rating and device support there is nothing between them.

Both are free to download. Surge sells 10 one-off in-app purchases. Knottled asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Surge against 5.0 for Knottled. That said, the two scores are not equally well evidenced: Surge has 5 ratings behind it against 1, so its average is the more settled of the two.

Surge ships an update every 3 weeks, Knottled every 10 days. The most recent releases landed on October 17, 2026 and October 20, 2026 respectively.
