# 海拔测量仪 vs GPS实时海拔

The clearest difference is ads: 海拔测量仪 at none against GPS实时海拔's shown. 海拔测量仪 also leads on device support (4 vs 2). GPS实时海拔's advantage is rating (4.8 vs 4.6) and update cadence (every 3 weeks vs every 2 months). On price, review sentiment, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. 海拔测量仪 sells 1 one-off in-app purchase and GPS实时海拔 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

GPS实时海拔 holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: GPS实时海拔 has 400 ratings behind it against 49, so its average is the more settled of the two. Written reviews complicate that: 92% of 海拔测量仪's written reviews are positive against 85% of GPS实时海拔's, so the app with the better star average is not the one people write more warmly about.

海拔测量仪 ships an update every 2 months, GPS实时海拔 every 3 weeks. Both last shipped on November 11, 2026.
