### 1/5 — Could be better

*2017-12-03*

Using it for aviation in Japan, but two main headaches exist:
1. Even though I am subscribed (paid) with the data provider, technically I should be able to make a copy for myself under most copyright conventions. However, with this app, when I make a screenshot, I get a cautionary message telling me of the copyright, and then I have to reboot it.

2. The reason that I require a screenshot, as a pilot, is that too many times while in the air, the app crashes just when I need the data... so not exactly great at this moment in time.
