Aid in Android App Development, Alpha testing

I am alpha testing my app (Lightly). I'd like all who are willing to try it out and tell me what you think. Please be as detailed as possible when describing the desired changes. Remember, I'm new and inexperienced so I ask that when you suggest changes to the design you show me what you mean (pic or gif), or else I may not know what your talking about.
