Default [APP][Nexus 5 Users only][BETA need testers] youtube-dl GUI

Hi. I need Nexus 5 users to test my app, because I know it sometimes fails on this device. The app is an android GUI for the youtube-dl open source python project and it will let you to view, share and download web embedded flash videos out of the browser. I would need error screenshot & logcat when it fails...Thank you.
