A-EFIS Black and White

Thanks to a friendly UI and a large number of possible adjustments it appears to be the best app in this category. Will run on iPhones and iPads in both portrait and landscape modes. On the iPad, it can run side-by-side with another application like SkyDemon, that does not offer such feature. Warning: the artificial horizon uses the “Russian logic” with the upper triangle and horizon both moving. The “Western logic” has the bottom triangle and the plane representation moving. Could be confusing and potentially dangerous.

I am extremely impressed with this application! Only using the free version for now but will be upgrading to the paid subscription the closer I get to finishing building my airplane. I am very thankful to have access to such a precisely formatted AHRS system as an augmentation to my primary flight instruments. Highly recommended! Many thanks to the developer!

Simply the best out there simple and intuitive. Doesn’t try to do too much and does what it does very well.

I have not flown with it yet, but if you think about it, a couple years ago it would cost big bucks to get this capability from Garmin or some of the other guys out there.

Has every thing I need to fly my Quicksilver MX. Groundspeed, altitude, rate of climb, G forces, compass etc. very good app

This EFIS system is simply the best bang for the buck for entry level efis,sailplanes,sport planes, experimental and other aircraft. I have used this system for years. It is easy to use,dependable and most important, reliable and accuracy is top notch. I have seen this company develop new software every few months. They don't just initiate a new product;they are always adding new features which makes the flying experience even better.The developer offers this system for free but it's worth it to spend a few bucks and get the color version. Then when your used to the system buying the full efis version with airspeed and barometric altitude is well worth it. You won't find a better price. Spaceman
