Viewer 2 is free to download; Tap Roulette costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Viewer 2 holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Tap Roulette has 136 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 50% of Viewer 2's written reviews are positive against 59% of Tap Roulette's, so the app with the better star average is not the one people write more warmly about.
Viewer 2 ships an update every 10 days, Tap Roulette every 4 months. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
