iPad and Android tablet app has offline mode which is very useful when your open house doesn't have service or when you don't have the wifi password. We recommend using Spacio with wifi whenever possible to make sure all leads are synced in real-time. You can also use a compatible Android tablet in offline mode. If you are anticipating a weak connection, it’s better to use your tablets in offline mode by turning off wifi on your device.
