Altimeter is not even close to accurate.
I have never had to write a negative review before purchasing this app. Save your money. I know its only $.99 but I hate getting ripped off for any amount. The altimeter showed me moving from 5ft to 120ft even though the phone was on the table not moving. I expected it to take some time to "settle down" but 3 min later it was still "bouncing" from 5ft to 101ft. While I didnt expect it to be "engineer accurate" I expected better than a 100 ft (approx) difference especially when the phone was not moving. Waste of money. As for the rest of the features, they seemed to work ok however I have checked the accuracy against my GPS.
