Ask HN: Launched the MVP for my new Android app. Any feedback?

I recently released an Android app to track and manage sales lists for small businesses. It will track your call queue, log previous calls and notes, and will allow you to report on past performance.

It's a basic MVP right now. I'm working on a few requested features and getting a presence on the web so customers can find me. Since my user base is small, I'd appreciate any feedback I can get for design, features or marketing.
