Each to their own. I have an Android for work, and much prefer my own iPhone
I contacted Blue mail btw @licquorice and they acknowledged that the two apps for different platforms are different and they are aiming to make them the same.
That just seems bizarre to have the same app with different features!
Out of interest, I installed the BT app on Android phone, and it does have the ability to add folders.
There must be something in IOS causing an issue if BT and Blue apps haven't got it.
