This application began calling samepager. It was ordered by a law firm of Miami. Finally, a spanish company (Iferendum Ideas) buy the application and called it Samedoc. With the new owners, the application had some improvements and new features.
The idea is to collaborate some users at the same time in the same document. Further, we develop a monthly payment system through Stripe and a sync system with Dropbox and Box.
At present, we still developing features for Samedoc, waiting the soon launch for the final public.
