# 指南针 vs 海拔表

The clearest difference is in-app purchases: 海拔表 at none against 指南针's 1. 海拔表 also leads on rating (5.0 vs 4.8). 指南针's advantage is ads (none vs shown) and ratings volume (40 vs 2). On price, device support and iOS requirement there is nothing between them.

Both are free to download. 指南针 sells 1 one-off in-app purchase. 海拔表 asks for nothing beyond the download.

海拔表 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: 指南针 has 40 ratings behind it against 2, so its average is the more settled of the two.

指南针 ships an update every 3 months, 海拔表 every 7 months. The most recent releases landed on September 26, 2026 and August 24, 2026 respectively.
