8. Neko Atsume
Neko Atsume is adorable and fun for the whole family, especially if you are a cat family! This app is only available on the App Store for iOS devices. Even though this app doesn't require WiFi and is free, entertainment is limited as it can't be played all at once, all day. There are in-app purchases available as an option but they are not necessary to enjoy the game. Be careful with the temptation of in-app purchases and make sure to discuss with your children about this prior to letting them play.
While your kids play this WiFi free game, you can listen to music or make phone calls with the airtube wired headset.
