# Ping vs knock(1)

The clearest difference is rating: knock(1) at 5.0 against Ping's 4.3. knock(1) also leads on in-app purchases (none vs 1). Ping's advantage is ratings volume (376 vs 1) and device support (3 vs 1). On price, update cadence and ads there is nothing between them.

Both are free to download. Ping sells 1 one-off in-app purchase. knock(1) asks for nothing beyond the download.

knock(1) holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Ping has 376 ratings behind it against 1, so its average is the more settled of the two.

Ping ships an update every 3 months, knock(1) every 2 months. The most recent releases landed on September 29, 2026 and September 26, 2026 respectively.
