# Bubble Level vs The Best Level

The clearest difference is rating: Bubble Level at 4.6 against The Best Level's 3.7. Bubble Level also leads on review sentiment (29% vs 0%) and ratings volume (3.1K vs 10). The Best Level's advantage is update cadence (every 3 months vs every 10 months) and iOS requirement (13.2 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Bubble Level sells 1 one-off in-app purchase and The Best Level sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Bubble Level holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Bubble Level has 3.1K ratings behind it against 10, so its average is the more settled of the two.
