Its not a blockbuster movie, more like a kind of indie movie I guess.
The plot is a female character who invents a device, together with other young people (students maybe?), that can move objects from one location to another. Just a few feet it seems. They calibrate the device to make it more accurate.
Suddently she is chased by someone (herself), and later she finds out that she has beeen dublicating herself! The device not only moves an object, it also creates a double somewhere else!
And her double has been locked inside a room by the others (students?) but still able to chase and attack her.
I think its from 2010-2015.
