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

The app connected to GPS a couple of times after I had first installed it, but thereafter it has always failed to locate a GPS signal from multiple outdoor locations. Rebooting my phone, stopping the app, clearing the app data has had no effect. The location based altimeter gives a figure, but this information is available online for free. My phone doesn't possess a barametric sensor, do I cannot say if that part of the app works.

The best altimeter I have found, and I tried loads. I am using it on a Samsung Galaxy S20 Ultra so it can use the barometric pressure sensor. On opening it finds the nearest airport, downloads its data and uses this to update the offset. With this I get an altitude within 30 feet of true (best possible if using whole millibars). I had to get the pro version to set a calibration offset because my phone sensor was nearly 2 millibats out but that is fine. Most apps can't be calibrated anyway so I

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.
