# 70 Degree vs Bubble Level Tool

The clearest difference is rating: Bubble Level Tool at 4.4 against 70 Degree's 2.9. Bubble Level Tool also leads on ads (none vs shown) and update cadence (weekly vs every 6 months). 70 Degree's advantage is in-app purchases (none vs 9) and review sentiment (20% vs 6%). On price and device support there is nothing between them.

Both are free to download. Bubble Level Tool sells 9 in-app purchases, starting at $3.99 per 7 days. 70 Degree asks for nothing beyond the download.

Bubble Level Tool holds the better App Store score, 4.4 against 2.9. That said, the two scores are not equally well evidenced: Bubble Level Tool has 2.5K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 20% of 70 Degree's written reviews are positive against 6% of Bubble Level Tool's, so the app with the better star average is not the one people write more warmly about.
