Hello, my name is Jonathan Barrantes, I am an Android developer, I already have enough experience in this, and this is the process to fix your application or project successfully:
1. Tell me in detail how you want the app to work. If you have any idea how you want it to look or any other idea, also tell me.
2. After both have been clear in the previous point, if you have any design that you want me to add to the app, you will pass it to me.
3. Ready, in a one or two days I will be fixed the app.
Regards! That is my proposal, I hope to help you in that app you are thinking about and make it together, successful.
