I have a fully paid for version. Looks like development has stopped on this. No updates or email responses. I wouldn't pay for an unsupported package.
Does not work as advertised Looks the part, but does not work as advertised. I have an instument that puts out, compass, wind (true and apparent), gps, and weather (MDA for pressure) sentences. The app will only show apparent wind. Contacted developer and no reply.. Do not waste your money
Promising but not useful yet This app looks great, and has good potential, but it's expensive, frustrating to navigate, inconsistent with the sentences it reads (reads some on one page, but not others), and provides no way to create polars. There's also no support link either in the app, or on their website. It also drains battery like mad, but I suspect there's not a huge amount the app devs can do about that.
Loved it Bravo
