Things like this are why Pokémon Go is such a great idea. I've personally found it having similar uses in my relationship too as a way to go out together more in a really relaxing and fun atmosphere which beats staying at home on the laptops easily. Hoping it stays like this for you, sounds like it's been a big thing for you :)
It's the same here for me. Although for me, it's more like my relationship with my parents is improving because of Go. Like today, I was the one that suggested we go out to an outdoor concert at a place where there were a few PokeSpots, and my parents and I walked around re-exploring the area. If we didn't go out and do that, we all would have been on separate ends of the house, not talking to each other.
Do your parents play too? One of my close friends has a similar situation to yours where he and his sister have barely ever spent time together and hardly ever speak to each other (not that I'm suggesting this was anything close to your situation, but a family spending their time apart from each other is relatable for a lot of people) but since Go came out they're spending loads of time outside together and have become very close as a family because of it. I know I've said this before but it's just so cool to see how big of an impact Go is having on peoples' everyday lives. It's such an awesome thing to happen to the world with the state it's in right now and honestly I'm just so glad it's going down as well as it is; I really do hope a lot of people are having the same effects that we are.
I'm the only one in my family crazy enough to buy a new phone for Pokemon. :) My parents are both fine with their lower-end phones. But they like Pokemon and learning about all the new little attractions that are PokeSpots, some of which we've never seen before even after living in the area for 40 years!
