I've Never Used a Calk, but I Don't Really Need One.

Play is a video book marking ap for saving stuff to watch later in cues that you can setp with in the ap. Snapdrop allows you to connect things together and transfer files via browser, and it's just really convenient. i've never seen it run particularly slowly, but i've never tried to do a particularly huge file under a hundred megites or anything like that. I think most everything 've tried to transfer has been under a hundredmegites,. But generally speaking i haven't found it really responsive with any large files.
