Over 100 aviation functions, conversions, and utilities, including functions that you won't find in any other E6B.
Each function uses the correct scientific formula to ensure accuracy. Other E6B apps rely on rules of thumb that can be up to 10% off. The most comprehensive, accurate, and easiest to use E6B on the App Store.

What is an E6B?
An E6B flight computer is traditionally an analog device resembling a combination slide rule and slide wheel that performs calculations specific to aviation. For example, an E6B can be used to calculate heading and groundspeed after taking into account forecast winds. An E6B is also used to calculate data used for performance planning such as density altitude. Our version goes beyond the analog E6B and even beyond all other E6B apps by including functionality to calculate time, rate and radius of turns, pivotal altitude (great for flight training use), and more.
▸ When selecting a field, any value in the field is automatically selected. Start typing to replace the value. Back button, Clear, and All Clear are still available for editing.
▸ Bug fixes and performance improvements
Changes in 1.8.0:
▸ Improved Keyboard: Added next and previous buttons for quicker data entry
▸ New: Functions > Plan Leg: Added hh:mm:ss units option - tap on the unit label next to the entry field to change the units.
▸ New: Added density, dry volume, power, and torque conversions
▸ New: Added Lift, Power & Torque functions to Extra Functions
▸ New: Added percent operation to Standard Calculator
▸ Fixed issue where some users could not enter negative altitude values in Plan Leg functions
▸ Time Calculator has been tweaked for users who need to add logbook times in hh:mm.
▸ Fixed an issue in the Standard Calculator where the order of operations was sometimes not being applied properly
▸ Optimized for iOS 14
▸ Misc other fixes and performance enhancements

Needs just one thing
I love the app already, I would just appreciate it so much if displayed times could also include seconds, at least as an optional setting.
Recently during training my CFI simulated loss of ILS, VOR and DME during an approach on a simulator session. I know normally you just notify tower and request visual but for the purpose of learning something new he had me continue the approach using an NDB station as reference for how many miles out I was and with calculate the time until I was exactly over the point where you initiate descent. (The NDB is aligned with the runway and yes we still use NDB in my country sadly).
Anyway, seconds are critical when dealing with such short distances and my CFI is not the kind of guy to just accept “1 min” over “1 min 30 seconds”.

Hi ZombieCOD, we’ve added HH:MM:SS as an option to HH:MM and decimal time in all functions. Just tap the units label next to the time field to switch. Please let us know if we missed anything, and thank you for using our app.
Several tools in this app will get used daily
I think this app has everything I need. Tools for figuring top of decent with wind could use tweaking because I would like to be able to put any known variable in and have it give me the unknown (it's possible I needed to dig deeper for one of the other tools). The time calculator will make catching up on my logbook a breeze! For 99c this is a must have from GA to Airline, there are things in this package for all pilots.
Great E6B! Some UI suggestions...
As a student pilot who is almost a PPL this app seems to cover everything I need. I do have some interface suggestions, though: 1.) A tab or enter key would be useful instead of the keyboard hide key. This way I can keep my finger near the bottom of the screen (on a iPhone XR) instead of having to move up and down the screen to move between data entry fields. And 2.) Move the keypad up a few pixels so that one doesn’t accidentally swipe up when using the bottom row of keys.

Thank you for the helpful feedback. We added navigation keys to the keyboard, and adjusted the keyboard to avoid issues on FaceID devices. These changes, along with other new functionality, are available in version 1.8.0 of the app.
