# Bubble Level vs Angle Finder

The clearest difference is ads: Angle Finder at none against Bubble Level's shown. Angle Finder also leads on rating (4.7 vs 4.5). Bubble Level's advantage is update cadence (weekly vs every 3 weeks) and review sentiment (41% vs 33%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Bubble Level sells 11 in-app purchases, starting at $1.99 per 7 days and Angle Finder sells 3 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Angle Finder holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 702 and 163 respectively. Written reviews complicate that: 41% of Bubble Level's written reviews are positive against 33% of Angle Finder's, so the app with the better star average is not the one people write more warmly about.

Bubble Level ships an update weekly, Angle Finder every 3 weeks. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
