I had a look but figured cats and dogs don’t speak the same language.
My cat passed away a few months before the big lockdown. We haven’t gotten another. She’s been missed.
I tried looking for another dog app but didn’t see anything that was anything more than entertainment.
I first saw these small buttons that dogs can step on to say words you can teach them with. That was cool but too expensive. (I’m willing to bet I’d have to put them up on a shelf most of the time or she’d just keep asking for food and to play outside.

)
If I ever find a dog app I’ll let you know.
