Share it is the best sharing app which uses hotspot bluetooth for file sharing. This app is available for free on Android in Google Play Store and IOS in app store. No wifi connection is required for file sharing and also you can share files wirelessly via Hotspot and Bluetooth. When you first install shareit you need to register yourself- enter your name- and choose a profile pic- you can either send a file receive a file. You can send apps games Music Sounds pictures data files etc. I personally use this app for file sharing and also I am having a great experience till date. I recommend you to download this app on your android or iOS device as this app can be of use anytime . Thank you all.
