# Bubble Level for iPhone vs Bubble Level + Spirit Level

Bubble Level for iPhone's advantage is ratings volume (112K vs 34) and iOS requirement (13.0 vs 16.6). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Bubble Level for iPhone sells 8 in-app purchases, starting at $4.99 per 7 days and Bubble Level + Spirit Level sells 7 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: Bubble Level for iPhone has 112K ratings behind it against 34, so its average is the more settled of the two. Written reviews complicate that: 35% of Bubble Level for iPhone's written reviews are positive against 100% of Bubble Level + Spirit Level's, so the app with the better star average is not the one people write more warmly about.
