# KAMI vs Ouros

The clearest difference is in-app purchases: Ouros at none against KAMI's 6. KAMI's advantage is update cadence (fortnightly vs every 5 months) and chart position (#179 vs unranked). On price, rating, review sentiment and ads there is nothing between them.

KAMI costs $2.99 and Ouros $2.99 up front. KAMI sells 6 one-off in-app purchases. Ouros asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.8 for KAMI against 4.9 for Ouros. That said, the two scores are not equally well evidenced: KAMI has 512 ratings behind it against 82, so its average is the more settled of the two. Written reviews are what separate them: 84% of KAMI's written reviews are positive against 90% of Ouros's.

KAMI ships an update fortnightly, Ouros every 5 months. The most recent releases landed on September 29, 2026 and September 25, 2026 respectively.
