Quickture is a tool that allows users to pre-announce their calls to each other via an animated video clip.
With Quickture, you can create a short video clip, attach a pre-recorded sound to it, and use that as a pre-announced video clip that will be received by the person you are calling (they must also have Quickture installed) before they receive the actual phone call.
NOTE: FOR THE APP TO WORK PROPERLY, YOU MUST SET PUSH NOTIFICATION ON.
