This Application should be a mix between a social platform and a selling plattform.
It schould work like a social plattform (like Facebook) were you have friends you can comment on certain things, like different objects, share with friends,...
To use tha App you just need to downlaoad it and make an account or just loggin with your Facebookaccount.
Everybody can upload all kind of non-legal stuff.
ex: If you want to sell your old computer just make a photo, write a little descrpition and upload it. Everybody can buy or sell things, B2B, B2C, C2B, C2C
Everything is free, we dont take any commission on selling or any inscription fee. The only way we would gain money would be from Adds, everybody can advertise the stuff he wants to sell, just like Facebook, we would also gain money from Offline data but not at the beginning
