I will create a mockup of your andriod app idea. Mockup because it will work just like you imagine, but with a basic UI design.

Please not that this service is only for andriod apps. And I won't be uploading your app to the app store.

I won't show you samples, but I will create  samples for you on-the-fly to prove my ability.

PM me or just post below. Don't worry, my rate is very affordable, especially if your app is not too complex.
