  1. 4/5Great so far

    Easy to use, I like the layout and having the local and zulu times at the top are a nice touch. Would like to have a pressure/density altitude calculator as well tho! Don’t know why thats not on here as it seems like a simple piece missing. Just plugging in elevation, altimeter setting and temperature.

  2. 5/5Perfect for Student Nav Logs to Quick Ref for Licensed and Rated Pilots

    This E6B app is perfect for filling out your nav log or for quick reference while in flight. It is designed to simply enter your known data and supplies your unknowns in a logical format. All the calculations are on a single page, so there is no page flopping when looking for a previous solution. The built-in keyboard facilitates the ease of use and reduces the chance of error especially when trying to get a quick calculation done. Highly recommend this E6B app.

  3. 5/5Perfect for nav logs

    Wasn’t going to download this at first but glad I went with it. Easy to use and helped me fill out the nav log quicker than the physical E6B calculator (including the app version). Accurate, robust app that hasn’t crashed on me ever which is always a good thing when you’re in the air. Love the custom keypad - makes data entry less error prone than the standard keyboards. Over all I highly recommend this E6B! Looking forward to updates (feature request for the developer: Would be great to have a METAR / TAF look up plus a way to plan out the entire nav log!)

    This useful app is a clear example of effective simplicity that reduces any visual clutter and distractions, resulting in a cleaner and user-friendly interface. It’s easy and straightforward to navigate through, and excels due to its attractive and clear-cut design. Highly recommend!

  5. 5/5Best nav log tool I’ve seen

    Simple and clear. Made pre-flight planning and performance calculations a breeze. Interpolation tool is a nice touch - haven’t seen it anywhere else. Simple and robust, with adequate details, which is what you want while flying.
