# UFO99 vs Janken Samurai

The clearest difference is in-app purchases: Janken Samurai at none against UFO99's 10. Janken Samurai also leads on ads (none vs shown) and rating (4.5 vs 4.2). UFO99's advantage is update cadence (every 2 days vs monthly) and review sentiment (69% vs 57%). On price, ratings volume, device support and iOS requirement there is nothing between them.

Both are free to download. UFO99 sells 10 one-off in-app purchases. Janken Samurai asks for nothing beyond the download.

Janken Samurai holds the better App Store score, 4.5 against 4.2. Both are backed by a comparable volume of ratings — 41 and 15 respectively. Written reviews complicate that: 69% of UFO99's written reviews are positive against 57% of Janken Samurai's, so the app with the better star average is not the one people write more warmly about.

UFO99 ships an update every 2 days, Janken Samurai monthly. Both last shipped on November 3, 2026.
