That is funny, when I look on my android phone, I can only find Imperihome in "Previously installed apps"on play store, not Imperihome Pro.
But when I look on a Windows computer and login to Play store, I see more apps, also the Imperihome Pro.

edit: now it does not show the pro version on my windows pc anymore.
definitely going to try other remote apps, 60 bucks per year is ridiculous for an app like this
