Wanted to install the app and do whatever I need to do to setup an account, etc ahead of unboxing my Dolphin for my pool that isn't done yet, but which app do I need? I searched the (iOS) app store for Maytronics and I see MyDolphin Plus, MyDolphin, DolphinTech, DolphinTech Plus all by Maytronics (and all with terrible reviews, but I digress) - so which one would I use, or what are the differences between them all?
