Skype is an online video calling app by which you can video call all your friends, or distance relatives if they are really far away from your place and for some point of time you want to catch over .It operates if both of the parties have internet connectivity, and working front camera on devices like phone or laptops.For a good video calling sessions you need to have a good connectivity of net so that the video calling sessions are un disrupted.I have been using Skype over a long time and it really helped a lot.
For overseas client handling I use Skype, for attending any Interviews I use skype mode as travelling to that place over short notice is not possible.I would definitely recommend skype for all, as in modern days it really acts like a boon for mankind.Can be operated on ios /android phones and laptops. Gonna rate it as 5 out of 5.
