# GenomeCache vs Knowt

The clearest difference is rating: Knowt at 4.7 against GenomeCache's 4.2. Knowt also leads on update cadence (weekly vs every 3 months) and ratings volume (11K vs 5). GenomeCache's advantage is in-app purchases (none vs 32) and iOS requirement (11 vs 16.4). On price, ads and device support there is nothing between them.

Both are free to download. Knowt sells 27 in-app purchases, starting at $5.99 per month. GenomeCache asks for nothing beyond the download.

Knowt holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Knowt has 11K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 44% of GenomeCache's written reviews are positive against 62% of Knowt's.

GenomeCache ships an update every 3 months, Knowt weekly. The most recent releases landed on October 6, 2026 and November 2, 2026 respectively.
