About this app

Altimeter is an handy Android application allowing you to get the true altitude above sea level (MSL) at your current location or any location on earth. It requires access to your device location to get raw altitude from the GPS signal and do not require a network connection to work. True altitude above mean sea level is determined using EGM96 Earth Gravitational Model. Main features are :

• Offline true altitude above sea level
• No network required (works offline and in flight mode)
• True altitude above sea level (AMSL using EGM96)
• Ordnance Survey National Grid reference system (OSGB36)
• Use Barometer or GPS Satellite
• Address at current location
• Save altitude at location
• Altitude accuracy estimation
• Horizontal accuracy estimation
• Altitude at any location
• Pick location on a Map
• Open photo geotags to display associated altitude
• Search for a location by name or address
• Universal Transverse Mercator coordinates (UTM)
• Military Grid Reference System coordinates (MGRS)
• Home screen widget to display altitude at current position

Network access is required to get the altitude of a location picked from the map.

Height above mean sea level (AMSL) is the elevation (on the ground) or altitude (in the air) of an object, relative to the average sea level datum. Normal GPS elevation considers the entire Earth as an ellispoid and differences up to 100 metres (328 feet) can exist between this ellipsoid height and true mean tidal height. The alternative, which is what we use in this application, is a geoid-based vertical datum such as the global EGM96 model.

Altitude vertical accuracy is defined at 68% confidence. Specifically, as 1-side of the 2-sided range above and below the estimated altitude reported, within which there is a 68% probability of finding the true altitude.

Enjoy!

Ratings and reviews

Stay away from this app! This has got to be the most egregious app, and there are many very nasty apps out there, for being nothing more than a tracking device. If you don't just click the box when setting up the app, but actually look at what you're agreeing to, you will be disgusted. They give a button to agree to everything but you will have to manually disable, I guessing around 100 trackers. There ara far better altimeters out there anyways.

I wrote down the longitude, latitude and the altitude of several different places and went back and rechecked them and they all read within a couple of feet of what they did the last time. This is a great tool when used when racing your motorcycle in the mountains with much varying altitudes you can make a quick fuel air ratio change in a straight away and consistently win the races with full power while the competition grows quite weak as the elevation rises. This seems to be a very good app!!

This app is clean and simple in doing what it is intended to do, without additional extra junky features to clutter. The 2x1 widget also looks great, though it doesn't seem to update as frequently as every 328ft (100m) per Settings. *Wishlist: (a) display altimeter in both feet & meter together, or have a quick toggle switch right on main app page instead of under Settings; (b) a smaller altimeter view that can be overlaid (Picture-in-picture) while running Maps/Waze.

What's new

Added the ability to track altitude from your connected watch or phone's lock screen via a persistent notification.
