# Angle Level vs Bubble Level

The clearest difference is rating: Bubble Level at 4.5 against Angle Level's 3.3. Bubble Level also leads on update cadence (weekly vs every 6 months) and ratings volume (702 vs 3). Angle Level's advantage is ads (none vs shown) and review sentiment (67% vs 41%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Angle Level sells 1 one-off in-app purchase and Bubble Level sells 11 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Bubble Level holds the better App Store score, 4.5 against 3.3. That said, the two scores are not equally well evidenced: Bubble Level has 702 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 67% of Angle Level's written reviews are positive against 41% of Bubble Level's, so the app with the better star average is not the one people write more warmly about.

Angle Level ships an update every 6 months, Bubble Level weekly. The most recent releases landed on July 12, 2026 and September 24, 2026 respectively.
