Hi,
As per my understanding you want an app which will have a spalsh screen or main screen after main screen , you want an interface which will get an image and audio from your sdcard , and than you want to share the same via click on button to social media.
I have 7+ year experience in this area, and i am confident to complete your requirement in 1 Day with the cost of $15.
I would like to work with you, kindly find my portfolio with my profile.
I am looking for a feedback from your side on my proposal.
Thanks in Advance
