About Barodroid
The altitude is computed from the local barometric pressure using the 1976 standard earth atmosphere formula. This formula, apparently works best at about 45 deg latitude, so if you are near the equator, like I am, then the default average elevation will be slightly offset from reality.
The observed value altitude can be calibrated, when the elevation at a location is already known. The approximate ground level elevation of where you are can be got from any mapping app.
Since the barometric pressure varies with the weather, this application may not give accurate results over a long period of time (say several hours), but the relative altitude/elevation is quite accurate for periods of ten's of minutes to less than an hour.
The rate of change of altitude is computed, which is useful to see how fast an elevator goes, or perhaps for skydivers, paragliders or birds.
Important note on Data Recording: Since the Android O/S is not meant to support an App running continuously as a background process, the only reliable way to continuously record data with this app, is to ensure that it is always a foreground process.

App History & Updates
What's Changed
Changed the app name because Google told me to.
For some user hints, please goto https://sites.google.com/site/msanders59/home/android-apps/barometric-altimeter
Upgraded a few things so that it works with Android 5.0 +, such as writing CSV file.

In order to establish a change, you need a proper baseline. This app would be fine if you are (or start) at sea level. For the rest of us, we need a means to calibrate the measurement according to our baseline altitude, since the higher you are, the more barometric pressure decreases. Where I am, it's not even close to what the weather people say is the barometric pressure, so how could the altitude be accurate?

After 2 weeks of trying this app, it has not got the height above sea level correct once.

App works and show reasonable results on screen. When trying to save the csv datafile, however, it fails. I think the problem is the different mount points of the SD card in different phones. The should be an option allowing the use to change the file location.

Fantastic sub-second graphing interval capability. Requesting an extra digit of resolution in barometric pressure display.

this app is great, except it keep running although we exit the app. i see it on battery status. please fix it, so it can really off when we exit the app. thanks anyway -Xperia Active-

Does what it is said. One of the best android apps around making use of newer device with barometric sensor. One thing that a bit annoying is time always display with AM/PM when set for 24-hr format.

I have spent a couple of years of my life leading walking and skiing holidays.My comments are related to how I use a real barometer/altimeter Weather - in the absence of a forecast, changes in atmospheric pressure, tracked every hour or two over a day or so, give some useful idea of likely weather changes. In particular, steep drops in pressure over several hours give indicate a very high probability of much worse weather arriving. Navigation on land - altitude gives a third factor that can be used in addition to the two basics of direction and speed. Typical accuracies given are plus/minus 10m in 500m ascent or descent within a 3-hour period. Altimeters should be re-set to known altitudes at the start of every day's trip, and at everymajor point where altitude can be read from the map. The apps I have had on my Samsung Galaxy Note fail in two ways. They record meaningless & minute fluctuations second-by-second; yet they do not allow for hourly recordings of pressure over a period of (say) 24 or 48 hours (which would be extremely useful). Indications of altitude give similarly (false) accuracies overwhelmed bymeaningless fluctuations
