# Bix Challenge vs Circle

The clearest difference is rating: Circle at 4.3 against Bix Challenge's 3.3. Circle also leads on ratings volume (5.5K vs 23). Bix Challenge's advantage is review sentiment (75% vs 43%) and update cadence (every 2 weeks vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Bix Challenge sells 5 one-off in-app purchases and Circle sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Circle holds the better App Store score, 4.3 against 3.3. That said, the two scores are not equally well evidenced: Circle has 5.5K ratings behind it against 23, so its average is the more settled of the two. Written reviews complicate that: 75% of Bix Challenge's written reviews are positive against 43% of Circle's, so the app with the better star average is not the one people write more warmly about.

Bix Challenge ships an update every 2 weeks, Circle every 2 months. Both last shipped on October 6, 2026.
