I've recently purchased (2 day's ago) a P3S and I'm looking at downloading the Litchi app. I currently have a Galaxy S5 (5.0) so from what I can see from my search, it should be ok. However, I am also looking to get an adapter so I can use my Ipad instead. Obviously the S5 is Andriod and the Ipad IOS. I tend to only use free apps on both devices so I'm just after some basic info. Will I have to pay twice for the app? Once from the play store and once from the Apple Store or is there a way of registering the download against your email address so it recognises you have already paid. I may not always use the Ipad so would like it on both devices.
