Handy app as long as you are connected

My darling wife got this app for me. We live 17' above sea level so it came in handy during last months trip to the Rockies. It was accurate when we drove up Mt. Evans. But in the Tetons, reception was intermittent -- also on the airline. Still, an interesting tool to have.

Most accurate altimeter I've found

Been using my Watch for altitude information when flying my ultralight aircraft and found other GPS altitude apps to be completely inaccurate and not precise at altitude. Using the barometric function with Altimeter+ has been incredibly accurate. I used it for a flight this morning and 15 hours later at a known elevation, I'm basically right on with the baro altimeter.

Annoying display and poor accuracy

The dial altimeter only has 1 hand, so it’s only accurate to the hundreds position.

Instead of smoothly incrementing up and down, one digit at a time, the digital altimeter spins wildly, in one direction only, like a slot-machine, making you think it’s broken.

You cannot tell at a glance, whether you are ascending or descending. have to wait for the slot-machine to stop spinning to see whether your altitude is higher or lower than the previous reading.
