# Nanzoo Clock vs Clockwiser

Both are free to download. Nanzoo Clock sells 1 one-off in-app purchase and Clockwiser sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Nanzoo Clock ships an update every 10 days, Clockwiser every 2 months. The most recent releases landed on October 23, 2026 and October 28, 2026 respectively.
