Pros:

1. It's open source which means anyone could grab the code and either develop this application or fork it to make your own.
2. Easy to use UI and login is via SteemConnect which goes a long way in securing trust with its users.
3. Easy to watch, comment and share videos on the go without needing to be on your computer.
4. Even though it has ads built in, it offers you an easy way to remove them without needing to pay those pesky extra charges that you will see on other apps.
5. Overall it's free and there are no hidden charges.
6. Strong roadmap of features to be developed, so if we see this application developed further we will see some good features which will be unique to this application.

Cons:

1. It's relatively buggy and quite a few improvements which could be made in order to assist the UX.
2. It doesn't seem to be as actively maintained as it could be and I would like to see more regular updates to this application.
3. It's only available on Android, so if you use iOS your out of luck and this application is going to be of use to you.
