About this app

The most downloaded Altimeter for Android that does not need internet to work!

- Altitude estimation with three different methods to be always sure to get a reliable measure, even without internet connection.
- Historical charts to see your excursions elevation gain.
- Maps with peaks' name and contour lines. Pick elevation from any point on the map.
- Pictures with impressed place name and altitude.

Altitude can be estimated:
- With satellites triangulation. Slow and less accurate but it works even with no internet connection.
- Taking the ground elevation at your current position from a global elevation map.
- Using the pressure sensor of your device (if available). It calibrates itself on pressure from the nearest weather station to improve accuracy.

As additional PRO features you can also:
- compensate systematic error of pressure sensor
- download a larger area of the global elevation map
- record altitude without opening the App
- pick elevation on the map with no limitation
- have no advertising

Ratings and reviews

Very accurate. Many users of GPS are not aware that the altitude given by GPS is based on a theoretical Geode of the Earth's surface. It can be up to 100' (33m) off. To get a correct altitude you have to have access to a database with the true altitude for every location. With that in mind, this app gets the GPS location (which is +- 5m for most locations on the Earth) and then finds the surveyed height. The location of my house is 227ft MSL and this app says 230ft MSL. Considering that I am holding it about 4' off the ground that is pretty darn good. It it is also cool that it also gives the altitude the current pressure is found in the Standard Atmosphere.

Full page ad popped after only about 20 seconds of trying it. Uninstalled. [Response] I'm sorry, but it happened the very first time I tried it and I had used it far less than 10 mins. I'm certain of it. Perhaps there is a bug somewhere. I looked at the 3 altitudes, then went to look at the settings, and the ad came up after I left the settings. I've been a professional developer for over 35 years--bugs are a part of the development life cycle. I sincerely hope you find the problem.

Update - this was apparently a temporary glitch - I've succeeded in downloading these areas now. ------- I bought the Pro version today. I used it on a local hike today and found it to be accurate. However, when I later tried to download several areas for offline use, only some of them successfully downloaded. One didn't respond to the download arrow at all. Another displayed an outline of an empty cloud and did not proceed to download. It appears that this app only works with certain areas.
