# Bubble Level vs Level Tool

Bubble Level's advantage is ratings volume (3.1K vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Bubble Level sells 1 one-off in-app purchase and Level Tool sells 2 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Level Tool holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Bubble Level has 3.1K ratings behind it against 1, so its average is the more settled of the two.

Bubble Level ships an update every 10 months, Level Tool every 2 months. The most recent releases landed on October 20, 2026 and October 11, 2026 respectively.
