# Klok AI vs Co

The clearest difference is review sentiment: Klok AI at 100% against Co's 0%. Klok AI also leads on in-app purchases (none vs 10) and update cadence (every 2 days vs every 9 days). Co's advantage is rating (3.7 vs 2.1) and ads (none vs shown). On price, ratings volume and device support there is nothing between them.

Both are free to download. Co sells 8 in-app purchases, starting at $3.99 per 7 days. Klok AI asks for nothing beyond the download.

Co holds the better App Store score, 3.7 against 2.1. Both are backed by a comparable volume of ratings — 7 and 3 respectively. Written reviews complicate that: 100% of Klok AI's written reviews are positive against 0% of Co's, so the app with the better star average is not the one people write more warmly about.

Klok AI ships an update every 2 days, Co every 9 days. The most recent releases landed on October 30, 2026 and November 9, 2026 respectively.
