Hi,
I'm Garry, A freelancer Mobile App Developer with 4+ years of Experience. I have a great command in native apps and I will make this app using latest libraries to improve the speed and quality of App. I will also provide single layout functionality that will make app compatible with all screen sizes of Android and iOS.
We can schedule a quick call on Skype to discuss these things in detail.
Looking forward for a positive response.
Thanks
Garry
