# Clinometer+ vs Angulus Pro

The clearest difference is update cadence: Angulus Pro at fortnightly against Clinometer+'s every 2 months. Clinometer+'s advantage is ratings volume (1K vs 26). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Clinometer+ sells 1 one-off in-app purchase and Angulus Pro sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for Clinometer+ against 4.6 for Angulus Pro. That said, the two scores are not equally well evidenced: Clinometer+ has 1K ratings behind it against 26, so its average is the more settled of the two.

Clinometer+ ships an update every 2 months, Angulus Pro fortnightly. The most recent releases landed on September 27, 2026 and September 22, 2026 respectively.
