Jetlagged in Seattle ,

A good start

It would be handy to be able to download data and save it for later use. For instance at the page where you enter the airport, it would be handy if the last looked up airports were shown and saved.

it used to work on my iPad mini

I tried to contact the developer via email, but got an immediate “bounced mail” notification.

I'm a “Luddite” that insists on using apps dedicated for the iPhone on my iPad mini-R. I've rarely run into a problem, but this app is one of them that won't run on the iPad mini — at least, normally.

It's a “GUI” issue, whereby the display is “jumpy”.

I also run this on an iPhone 5S, and it runs fine.
