# Pendulum vs Score Uno

The clearest difference is rating: Score Uno at 5.0 against Pendulum's 4.2. Score Uno also leads on update cadence (daily vs every 9 days). Pendulum's advantage is ratings volume (16 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Pendulum sells 5 one-off in-app purchases and Score Uno sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Score Uno holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Pendulum has 16 ratings behind it against 1, so its average is the more settled of the two.

Pendulum ships an update every 9 days, Score Uno daily. The most recent releases landed on October 14, 2026 and October 3, 2026 respectively.
