The application has two sections.

The main section functions include:

ALTITUDE->
-Pressure Altitude
-Density Altitude
-True Altitude

Ratings and reviews

By far the most easy to use and well laid-off "e6b-type" app I tried. Very easy to use for x-country planning! I have two suggestions: (1) Use the number keyboard for numeric fields as opposed to the alphanumeric "standard" kb, (2) Being able to enter time fields without having to enter 0s for unused fields would make it faster. Otherwise great app!

Trying to enter a time is a nightmare. The auto tab that happens whenever I enter or delete the second digit of a time input made me want to throw my phone out of the airplane. If that wasn't enough to give this app a one star, it also has no way of saving or carrying over calculations to other steps in the planning or flight operations.

This kind of software does by no means require permanent modifications to stay on top of the laws of physics, it's no anti-virus. The overwhelming majority of users will not need it on a daily or even weekly basis, and calculating a couple well-established formulas should not be so expensive, just because they are presented in a form that is more convenient than a general calculator for pilots. The price would be steep as a purchase -- as a recurring subscription, it is outrageous. Uninstalled.
