# 海拔 Pro vs Altitude Compass

The clearest difference is ads: Altitude Compass at none against 海拔 Pro's shown. Altitude Compass also leads on update cadence (every 5 days vs monthly) and ratings volume (16 vs 2). 海拔 Pro's advantage is monetization model (free with in-app purchases vs paid). On price, rating, in-app purchases and device support there is nothing between them.

On the App Store both sit at effectively the same score — 5.0 for 海拔 Pro against 5.0 for Altitude Compass. That said, the two scores are not equally well evidenced: Altitude Compass has 16 ratings behind it against 2, so its average is the more settled of the two.

海拔 Pro ships an update monthly, Altitude Compass every 5 days. The most recent releases landed on October 3, 2026 and October 16, 2026 respectively.
