Variometer-Plus for Android
Great concept but useless Don't waste your money.
Does what it is supposed to. I think all the bad reviews re the vario accuracy must be using GPS based... which is silly. On the Xperia active it works great.
Doesn't work, even on Samsung Galaxy S3 a phone that has a Bult-in Baro. Dont waste your money, get XCSOAR, its free or Gaggle.
Don't recommend for nexus s 2 users.
The idea is good and viable. The system GPS has, in principle, precision and speed enough to be used in a variometer. Perhaps the GPS on Defy has no conditions to carry out the task. Perhaps the variometer-plus software has bugs.
As good as it can be with the phones hardware.
Useless:(it just looks like vario,concept is interesting,but not more.sorry.
Nice concept, however, neither the gps nor the phone's accelerometer are sensitive enough to make the variometer of any use. No beeps in 5 m/s lift.
Very nice app and less expensive as a real vario!

Absolutely outstanding app. replaces my $700.00 vario AND does more! (moto X, droid 4.4.2)
