# Kemo vs 3

The clearest difference is rating: Kemo at 4.6 against 3's 3.4. Kemo also leads on ratings volume (92K vs 69) and chart position (#51 vs unranked). 3's advantage is review sentiment (59% vs 17%) and ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Kemo sells 12 in-app purchases, starting at $3.99 per month and 3 sells 15 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Kemo holds the better App Store score, 4.6 against 3.4. That said, the two scores are not equally well evidenced: Kemo has 92K ratings behind it against 69, so its average is the more settled of the two. Written reviews complicate that: 17% of Kemo's written reviews are positive against 59% of 3's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 15, 2026 and October 14, 2026 respectively.
