# Blind Buzzer vs ZeroIn

The clearest difference is ads: Blind Buzzer at none against ZeroIn's shown. Blind Buzzer also leads on ratings volume (49 vs 1). ZeroIn's advantage is rating (5.0 vs 4.8). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Blind Buzzer sells 1 one-off in-app purchase and ZeroIn sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ZeroIn holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Blind Buzzer has 49 ratings behind it against 1, so its average is the more settled of the two.

Blind Buzzer ships an update fortnightly, ZeroIn every 2 weeks. The most recent releases landed on October 10, 2026 and October 4, 2026 respectively.
