It’s like tomodachi life for mobile! You can get it on iOS and Android! So your ipod should run it. I had a bit of beforehand experience with it cuz I downloaded the Japanese one which was thankfully all in English, but it’s really fun!
You can also add anyone who is in the same room as you, or connect it to your Facebook and Twitter and search for friends that have also linked it!

It’s really fun, 10/10 so far and it works somewhat like a messaging system in a way.
