# Measure Angles vs Redodo MPPT

The clearest difference is rating: Measure Angles at 4.2 against Redodo MPPT's 3.3. Measure Angles also leads on update cadence (fortnightly vs every 7 months) and ratings volume (2K vs 3). Redodo MPPT's advantage is in-app purchases (none vs 8) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Measure Angles sells 8 in-app purchases, starting at $4.99 per 7 days. Redodo MPPT asks for nothing beyond the download.

Measure Angles holds the better App Store score, 4.2 against 3.3. 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 67% of Redodo MPPT's, so the app with the better star average is not the one people write more warmly about.

Measure Angles ships an update fortnightly, Redodo MPPT every 7 months. The most recent releases landed on September 26, 2026 and June 6, 2026 respectively.
