Verdict
The clearest difference is price: GPS海拔测量仪 at Free against Realtime Altimeter Pro's $1.99. GPS海拔测量仪 also leads on update cadence (every 3 months vs every 22 months) and review sentiment (92% vs 68%). Realtime Altimeter Pro's advantage is in-app purchases (none vs 1). On rating, ads, device support and iOS requirement there is nothing between them.
