# Chrono vs No

The clearest difference is update cadence: Chrono at every 3 days against No's every 10 days. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Chrono sells 6 in-app purchases, starting at $4.99 per month and No sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Chrono ships an update every 3 days, No every 10 days. The most recent releases landed on October 25, 2026 and October 16, 2026 respectively.
