Pro Altimeter is actually the most accurate Altimeter on the Android market (up to +/- 10 cm with barometric sensor) for sports and leisure activities.
The measurement provided by the GPS receiver is Geoid compensated and will improve its accuracy after a few minutes, depending on atmospheric conditions.
If your smartphone or tablet is equipped with a barometric sensor, and if you take care of calibrating the QNH (barometric pressure corrected), you will obtain a very high accuracy.
A time graph allows you to track the variation of the altitude. Pro Altimeter is also offering altitude alarm, stopwatch, cumulative ascent and descent, color themes.
You can choose the refreshing frequency of measurements and graph that suits you best depends on your activity.
*** If you encounter a malfunction, rather than putting a bad score and a nasty comment;-) please send us an email, we will refund you immediately and of course correct any bug as soon as possible. Thank you in advance for your support. ***
