Verdict
The clearest difference is ads: Level Tool at none against Bubble Level's shown. Level Tool also leads on rating (5.0 vs 4.6). Bubble Level's advantage is ratings volume (3.1K vs 2). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Bubble Level sells 1 one-off in-app purchase and Level Tool sells 2 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Level Tool holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Bubble Level has 3.1K ratings behind it against 2, so its average is the more settled of the two.
