【實用社交app】I-FI|最夯免費app-綠色工廠好玩App

*Airplane mode/Off the Grid Texting!*IFI lets you chat with no reception and no internet connection. I-FI works using a peer-to-peer network that uses devices as "relays" so that you can communicate with your friends and contacts when you otherwise wouldn't be able to, due to circumstances such as natural disasters, sporting events or crowded areas where reception or WI-FI wouldn't otherwise be available.
