As a student pilot I had been pricing garmin gps units. Even the used 295s were selling for $500+ on eBay. So I bought an iPad and this app instead and just in time for me to take on my first solo cross country.
The documentation could be a bit better for how to use it to its full potential, but I was able to create my flight plan easily.
Took it on my cross country trip and it worked great!
Being able to see a nearby airport or vor and just tap it to see all the key info such as frequencies and runways is much easier than trying to read the numbers on a sectional chart.
If you fly and want an easy to use in flight gps with a great display... This is it!
