# KnowWake vs C

The clearest difference is in-app purchases: KnowWake at none against C's 11. KnowWake also leads on update cadence (every 11 days vs every 6 weeks) and iOS requirement (13.0 vs 15.1). C's advantage is rating (4.5 vs 4.1) and ratings volume (2.3K vs 250). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. C sells 10 in-app purchases, starting at $1.99 per month. KnowWake asks for nothing beyond the download.

C holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: C has 2.3K ratings behind it against 250, so its average is the more settled of the two. Written reviews complicate that: 55% of KnowWake's written reviews are positive against 51% of C's, so the app with the better star average is not the one people write more warmly about.

KnowWake ships an update every 11 days, C every 6 weeks. The most recent releases landed on October 7, 2026 and October 13, 2026 respectively.
