# Bubble Level vs Angle Finder

The clearest difference is ads: Angle Finder at none against Bubble Level's shown. Bubble Level's advantage is update cadence (weekly vs every 3 weeks) and review sentiment (43% vs 29%). On price, rating, in-app purchases and monetization model 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.

Written reviews complicate that: 43% of Bubble Level's written reviews are positive against 29% of Angle Finder's, so the app with the better star average is not the one people write more warmly about.
