# Bubble Level vs Level Tool

The clearest difference is rating: Bubble Level at 4.6 against Level Tool's 4.0. Bubble Level also leads on ratings volume (3.1K vs 34). Level Tool's advantage is update cadence (monthly vs every 10 months) and iOS requirement (13.0 vs 17.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Bubble Level sells 1 one-off in-app purchase and Level Tool sells 5 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Bubble Level holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Bubble Level has 3.1K ratings behind it against 34, so its average is the more settled of the two. Written reviews complicate that: 29% of Bubble Level's written reviews are positive against 36% of Level Tool's, so the app with the better star average is not the one people write more warmly about.

Bubble Level ships an update every 10 months, Level Tool monthly. The most recent releases landed on October 23, 2026 and October 20, 2026 respectively.
