# Angulus Pro vs OrthoMeasure

The clearest difference is in-app purchases: OrthoMeasure at none against Angulus Pro's 3. OrthoMeasure also leads on rating (5.0 vs 4.6) and update cadence (every 5 days vs fortnightly). Angulus Pro's advantage is ratings volume (26 vs 1). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Angulus Pro sells 3 in-app purchases, starting at $2.99 per month. OrthoMeasure asks for nothing beyond the download.

OrthoMeasure holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Angulus Pro has 26 ratings behind it against 1, so its average is the more settled of the two.

Angulus Pro ships an update fortnightly, OrthoMeasure every 5 days. The most recent releases landed on September 22, 2026 and September 21, 2026 respectively.
