# Blackbox vs KAMI 2

The clearest difference is ads: Blackbox at none against KAMI 2's shown. Blackbox also leads on update cadence (every 9 days vs every 2 months) and chart position (#33 vs unranked). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Blackbox sells 10 one-off in-app purchases 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 Blackbox against 4.7 for KAMI 2. That said, the two scores are not equally well evidenced: Blackbox has 109K ratings behind it against 15K, so its average is the more settled of the two. Written reviews are what separate them: 93% of Blackbox's written reviews are positive against 84% of KAMI 2's.

Blackbox ships an update every 9 days, KAMI 2 every 2 months. The most recent releases landed on September 30, 2026 and October 1, 2026 respectively.
