Based on Sporty’s popular handheld E6B Electronic Flight Computer, the E6B app has been designed from the ground up to make the most of iOS on the iPhone, iPad and Apple Watch. The software is based on the tried and true formulas and algorithms developed over the years by Sporty’s team of over 50 pilots.

Its pilot-friendly design makes quick work of any navigational, conversion or fuel problem and it also performs conventional arithmetic calculations.

The advanced timer/clock feature simultaneously tracks Zulu, Local and Home time zones. The timer counts either up or down, and will display an alert when reaching zero.

Apple Watch display needs improvement

I had hoped to use the Apple Watch app, but the display only shows the top half of the numbers. Perhaps this is because I have the original Apple Watch? I also find the process of entering numbers to be cumbersome. If I click on an item to change the value, I first have to backspace out the current value before entering the new value. I’d prefer that it just let me start typing the number right away instead of going through those extra steps.

But I’m happy that this app is available. I haven’t used it much yet, but I’m sure it will be useful.

Can I have the old one back?


Not as useful. I've heard people report missing functions. In my case I had favorites, a small group of functions I actually used in flight. In its place is a list of "saved" functions. I have no idea who decided to save them for special treatment.

unlike what I said in my original post, you can add and remove Saved items, I guess I was expecting to be able to do that from the list, like at least 90% of the other apps I use. Instead this app made a design decision to put that ability in the numeric keyboard when using a function. IOW, to remove a starred favorite, you don't just swipe it away or un-star or edit the list, you have to use it to lose it.

Developer Response ,

Thanks for checking out the latest update to the E6B app. The functions you see in the Saved list are placed there as examples, but you can remove them at any time by opening the specific function or conversion, and then tapping the star button located at the top right of the keypad when using the function.

You can also add any function or conversion to Saved list by tapping the "Add to Home" button at the top right of the keypad when using that function or conversion.

Nice app but needs a better look

Agree with other reviewers that larger text would be better. Lots of wasted space and not really attractive pages, especially on an iPad which a lot of us are using. Would be nice if the timer made a sound when count was reached.
