Hi, I'm Vlad Linnik from Stone Labs, we are a Lithuanian company and have been developing apps for iOS, Android and WP7 for 5 years.
It would be a fun to work on this project, yet, how exactly will the card change be implemented? With the help of some stop-video function and then cutting the image to the card, this way?
And for sharing, how many social networks are there going to be? It influences the estimation greatly.
Now, without knowing the essence of changes, we estimate it in 66 hours or about 1000$.
