# Revise AI vs Time Glass

The clearest difference is ads: Revise AI at none against Time Glass's shown. Revise AI also leads on iOS requirement (13.0 vs 16.4). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Revise AI sells 5 in-app purchases, starting at $6.99 per 7 days and Time Glass sells 1 in-app purchase, starting at $2.99 per year. Whichever you choose, the download price is not the number that matters.
