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.

### 5/5 — Nice app.

*2024-03-09*

Includes The function is necessary to plan Flight.

**Developer response:** Thank you for your feedback! We’re glad to hear that you find the app helpful for planning flights. Our goal is to provide the tools and functionality pilots need to make flight planning as efficient and reliable as possible. If you have any suggestions or features you’d like to see added, feel free to reach out through the Support button in the app. We appreciate your support and wish you safe and successful flights!

### 5/5 — Excellent

*2023-09-13*

I use this all the time, easy to use.  It has everything i need in one app.

**Developer response:** Thank you for your fantastic feedback! We’re thrilled to hear that the app has everything you need and that it’s easy to use. Knowing it’s a tool you rely on regularly means a lot to us. If you ever have suggestions or features you’d like to see, feel free to reach out—we’re always looking to improve.

### 4/5 — Calculation problem?

*2022-11-29*

Update: Reply received from the developer. Great to hear from them and no idea why I didn’t receive the original reply they say they sent. This review and reply process is poorly designed (by Apple) … but that’s a separate issue.

Updated to 4 stars because it’s a well designed app that is very easy to use and the reply is appreciated. Kudos for that.

The issue with no guidelines or instructions provided remains. The vast majority of the functionality in the app is perfectly straight forward. If you can use a real life manual e6b this will be a no brainer. This is faster and usually easier. It’s a pretty good app. But the lack of any user manual makes a couple key calculations either very difficult to verify or too easy to use incorrectly (and receive the wrong output as a result). 

For the record, I understand the calculations well enough to do them manually with paper and pencil. A user quick guide would likely solve any remaining confusion. Or at least allow verification of accuracy.

**Developer response:** Hi Jonathan,

We received your email at 10:13 AM on November 6, and replied at 4:17 PM that same day.

The true altitude function is in fact accurate. As stated in the app description, we use the correct scientific formulas for all functions. Other E6Bs often rely on rules of thumb and tables that provide reasonable approximations.

### 1/5 — Pop ups

*2022-10-18*

Trying to use this app and every time I back up it asks me to review the app! Brutal. Oh and the review requires a nickname and all have been taken, 6 attempts so far! Seriously

**Developer response:** Did leaving a negative review stop the prompts and resolve the user ID issue on the App Store?

If you had contacted us, we would have informed you that Apple controls when and how often in-app review prompts are displayed. Developers have no control over that. Apple also controls the App Store, and developers can't fix issues like the App Store repeatedly asking you to create a username to leave reviews. 

We would also have informed you that you can disable in-app review prompts by opening the Settings app, selecting -  App Store -> Scroll to bottom -> then disable In-App Ratings and Reviews.

As far as the issue with your username on the App Store, you can contact Apple at https://www.apple.com/contact/

### 5/5 — Low work load

*2022-10-07*

Love this app use it on my iPad 10.2. Much faster, and way less workload in cockpit then regular electronic flight computer and way better then spinning the wheel and struggling to read it. So that makes for a safer flight.

### 5/5 — Saved me a lot of time!

*2022-08-29*

Love this flight computer. Extremely user friendly and awesome!

### 5/5 — Top free

*2021-12-27, version 1.9.0*

Top free calculator so far

### 5/5 — E6B

*2021-05-25, version 1.8.5*

This is THE BEST APP!!! Great design and very easy to use. Satisfaction guaranteed!!!
Thank you very much!!!

### 5/5 — Nice E6B

*2020-09-30, version 1.8.0*

A nice E6B. Developer is responsive and works to update and maintain app long term.

### 4/5 — No Seconds??

*2020-09-14*

I like this app. Clean and it remembers values set throughout the different views

However, I’m disappointed that any time measurements (distance over time, etc) only has HH:MM and will not include seconds.

Despite the top review from 2 years ago mentioning this, it’s still not added. Disappointing for a $10 app.

**Developer response:** Hello, thank you for your feedback. We added seconds to time fields in all functions in version 1.8.0 of the app. Tap on the unit label to change between HH:MM, HH:MM:SS, and decimal time.
