Hi! I downloaded the app since I have an Android device that I use for work. I would like to suggest a few things, most of which pertains to the quality of life side of the app.

1. Try to add an option to view it in Landscape mode.
2. App images does not scale well on tablet devices.
3. Try integrating your app with others, for example Gyft or Amazon.

Now for the good part. I have no problems whatsoever with the application. It glides smoothly, runs fast, has a small storage requirement and the best thing is, it does not ask for any permissions.

My overall rating for this aside from the quality of life suggestions, I would rank it at 4.5 stars. This makes it much easier for people who prefer shopping using crypto currencies. Who knows, this might be the next big thing and help crypto currencies be noticed by a lot more people.
