Just search aquascape tools on Amazon, should be one of the first results. I’ve got two of the exact same sets. (Only bought one but for some reason Amazon sent two lol)

I’m in the same exact boat as you friend, used rif for basically a decade. I’ve been using Jerboa as well, it’s alright but I know what you mean, not the same. I have heard a lot of good things about boost, they’re still finishing up their app, you can find it in the app store and pre-register now. I’m hoping that finishes soon and can fill that void, it looks like it can be customized to look kinda similarly to rif.
