# RADD vs KAMI 2

The clearest difference is ads: RADD at none against KAMI 2's shown. RADD also leads on update cadence (fortnightly vs every 2 months) and iOS requirement (12.0 vs 15.0). KAMI 2's advantage is ratings volume (15K vs 29). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. RADD sells 1 one-off in-app purchase and KAMI 2 sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for RADD against 4.7 for KAMI 2. That said, the two scores are not equally well evidenced: KAMI 2 has 15K ratings behind it against 29, so its average is the more settled of the two. Written reviews are what separate them: 76% of RADD's written reviews are positive against 84% of KAMI 2's.

RADD ships an update fortnightly, KAMI 2 every 2 months. The most recent releases landed on October 12, 2026 and October 20, 2026 respectively.
