The broadcasting app Hype allows you to send "sparkles" to a broadcaster to show your appreciation for their live stream. You can send sparkles on the app the same way you send hearts on Periscope -- by tapping your display during a live broadcast. Remember unlike Periscope, Hype allows broadcasters to archive old videos. You can only send sparkles during a live broadcast and not to old videos.
