# Measure Angles vs Spur Gear Calculator

The clearest difference is review sentiment: Spur Gear Calculator at 100% against Measure Angles's 47%. Spur Gear Calculator also leads on in-app purchases (none vs 10) and ads (none vs shown). Measure Angles's advantage is rating (4.2 vs 3.7) and update cadence (fortnightly vs every 12 months). On price and device support there is nothing between them.

Both are free to download. Measure Angles sells 10 in-app purchases, starting at $2.99 per 7 days. Spur Gear Calculator asks for nothing beyond the download.

Measure Angles holds the better App Store score, 4.2 against 3.7. That said, the two scores are not equally well evidenced: Measure Angles has 2K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 47% of Measure Angles's written reviews are positive against 100% of Spur Gear Calculator's, so the app with the better star average is not the one people write more warmly about.

Measure Angles ships an update fortnightly, Spur Gear Calculator every 12 months. The most recent releases landed on November 6, 2026 and November 1, 2026 respectively.
