About this app

Altimeter is a high-precision elevation measurement app that gives you the accurate altitude above mean sea level (AMSL) anywhere on Earth. The app combines GPS altitude, Fusion Map elevation, and EGM96 geoid correction to eliminate the large errors commonly found in standard GPS readings.
It works completely offline, even in airplane mode, providing reliable altitude data wherever you go.

The app also visualizes your elevation changes with clean, beautiful altitude graphs, making it perfect for hiking, trekking, drone flying, cycling, aviation, and any activity where accurate elevation matters.

🔧 Key Features
- Dual altitude system: GPS altitude + Fusion Map (EGM96 geoid)
- Accurate AMSL elevation anywhere in the world
- Offline altimeter
- Beautiful elevation graphs for trend visualization
- Current/Max/Min location altitude + address
- Vertical altitude Max/Min graph

🌍 Why GPS Altitude Alone Is Not Enough
Standard GPS altitude is based on an ellipsoid model of Earth and can be off by dozens of meters from true sea-level height.
This app applies the EGM96 geoid model (Fusion Map) to deliver highly accurate real AMSL elevation, not just raw GPS height.

🛰 Optimized for Offline Use
- Works with GPS only, no internet required
- Ideal for mountains, remote areas, flights, and international travel

🎯 Perfect For
- Hiking & mountain trekking
- Drone pilots (UAV)
- Paragliding & aviation
- Cycling & outdoor sports
- Travelers and explorers
- Field survey, science, geography study
