Hello. Sorry but It has awful bugs. I already have and account but it does not recognise my gmail account. But I found a way to log in. I touched the "I forgot my password" and then could log in without the need to change my password. And also I did not tranfer any files but it says that I did transfer 4 GB which made me feel insecure. If they don't fix these problem so I don't recommend this app at all.
