Whatever you do , if you are looking for an aviation app, do not buy WingXPro. WingX does one thing good, they allow almost all ADS-B units to work with the program. After that everything is downhill.
WingXPro does not have the reliability one needs when flying. Their quality control is near nonexistent. The previous flight I took the weather was not working. Sent them an email, and it was working 2 days later...not when I needed it.
WingX came out with another update this week. They installed a numerical VSI on the top of the map page. I do not know what these people were thinking. Vertical speed with GPS is determined by ones location not the altimeter. If you are flying in level flight the VSI will give you a notice of how many feet up or down you are going...even though you are level! Unfortunately WingX has not provided a way to turn this nuisance off.
They also did not check their program before updating it. There are 2 weather blocks on the Map page. Underneath them is a notice that says “loading...” This is fine if you are connected to the internet but useless in flight. I do no know if this burns more battery on the IPad constantly searching when there is no internet connection. It worked fine with ADS-B In until this update. It would also be nice to turn off the 2 weather blocks in flight as they are useless, not being able to update weather in flight.
WingXPro has some wonderful features, but it is not reliable enough to bet your life on. I have one more year to go on my subscription and can not wait to switch to ForeFlight. ForeFlight has only had one glitch that I know of, and it was corrected in one day.
