Verdict

The call

The clearest difference is ads: Bubble Level Plus+ at none against Measure Angles's shown. Bubble Level Plus+ also leads on rating (4.6 vs 4.2) and ratings volume (15K vs 2K). Measure Angles's advantage is update cadence (fortnightly vs every 2 months) and review sentiment (47% vs 38%). On price, in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Bubble Level Plus+ holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Bubble Level Plus+ has 15K ratings behind it against 2K, so its average is the more settled of the two. Written reviews complicate that: 47% of Measure Angles's written reviews are positive against 38% of Bubble Level Plus+'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Measure Angles ships an update fortnightly, Bubble Level Plus+ every 2 months. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
