There are many apps available in the playstore through which you can share your data. But among all the apps, the most simple and amazing app is Shareit. You can use it to share any kind of data between android and iOS devices.
The speed is superb and the best part is the ease with which it can be used.There are many other apps which claim to give high speeds but I have compared and found out that this is the best one. It is free as well and you will really enjoy using this app. I bought a new phone and I used shareit to transfer my data to it from the older phone and it worked wonders saving a lot of time.
