# Compass vs 海拔表

The clearest difference is in-app purchases: 海拔表 at none against Compass's 2. 海拔表 also leads on rating (5.0 vs 4.6) and iOS requirement (13.0 vs 15.0). Compass's advantage is update cadence (every 2 weeks vs every 7 months) and ratings volume (26 vs 2). On price, ads and device support there is nothing between them.

Both are free to download. Compass sells 2 one-off in-app purchases. 海拔表 asks for nothing beyond the download.

海拔表 holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Compass has 26 ratings behind it against 2, so its average is the more settled of the two.

Compass ships an update every 2 weeks, 海拔表 every 7 months. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
