Let me start with a thank you. Thank you for sharing this beta with me. As a professional tester I'm excited to test someone else's software instead of the software for my company ;-).
My first impressions is very good. You did a great job adapting the Android guidelines to your app. The look and feel is so much beter that the "reader". In the first 5 minutes of testing I had one crash. I already send the report to the developers. Unfortunately, it wasn't easy to reproduce. I will keep trying though.
At this moment the first thing I miss is navigation buttons on the website. Normally I would use the back button, but (ofcourse) the back button now returns to the 1Password app.
I will continue to use/try/test this app and will share my thoughts with you. Again, a very good start! Tnx.
