I am using this app from the last three years and getting amazing results. As named, this app made sharing so easy and quick for me. No matter what it is I wanna share either videos, snaps, audios or apps Shareit allows all that with the same quality.
This app is available on Play store.Can be installed from there.
Shareit also have a great feature of scaning QR code and this provides quick connectivity with the other devices. Shareit works for all kinds of devices either it be PCs, Androids or others.
Also has a messaging facility for the connected devices.
But, according to me it have some cons too. The videos provided in it are little inappropriate. And have alot of adds in it. And sometimes you can have connectivity problems too.
But in terms of time saver it works well.
You can give it a try while keep searching for a better app for sharing.
