Open the app. Each phone appears on the other's radar. Tap a name and call. Local calling needs no account, no phone number and no sign-up. Nothing to configure. New to the app? Settings > How to use explains every feature step by step. CALLS - Clear voice calls over your local network - Video calls when you want to be seen - Switch call audio between speaker, earpiece, Bluetooth and headphones - See the connection quality live while you talk MESSAGES - Chat with anyone nearby, during a call or on its own - Conversations are saved, with typing indicators, read receipts and timestamps - Long-press a message to copy it FILES - Send photos, videos and documents to people nearby, encrypted and with no internet - Send files during a call, without hanging up - Open a photo or file in WiFi Calling from the Share menu to send it on - If a transfer is interrupted, pick it up again with one tap FIND AND CONNECT - See everyone nearby on a live radar screen - Connect instantly by scanning a QR code - Search your contacts and call history - Review past calls and the messages from them MAKE IT YOURS - Set a display name and photo that others see - Light and dark themes, with a colour of your choice for each mode - Available in English, Spanish, Portuguese, Hindi, Nepali and Arabic NO ROUTER? NO PROBLEM Turn on Personal Hotspot on one phone and let the other join it by scanning a QR code. You get the same direct calling with no router, no broadband, and no SIM in either phone. GLOBAL MODE (OPTIONAL) Want to reach someone who is not on your Wi-Fi? Sign in, swap friend codes, and call, video call or message them over the internet, wherever they are. You only appear to people you have accepted, and you can remove, block or report anyone. Local calling works without it. PERFECT FOR - Buildings with no mobile signal: basements, warehouses, hospitals, workshops - Farms, building sites and large properties that need a simple intercom - Homes where children or older relatives have a phone but no plan - Hotels and hostels abroad, without roaming - Camping and remote trips, using one phone as the hotspot - Spare phones and tablets with no SIM, turned into handsets BUILT FOR PRIVACY Local calls, video, messages and files travel straight between the two devices across your own network and never pass through a server. Your contacts never leave your phone. Local calling needs no account. Global mode, if you choose to use it, needs an account, and its messages are delivered through our servers. WHAT YOU NEED - Both people need the app installed - Both devices must be on the same Wi-Fi network or hotspot - Some public and workplace networks block device-to-device traffic. If yours does, open Connect and pair the two phones by QR code instead This app connects devices to each other over Wi-Fi. It does not dial ordinary phone numbers and is not a replacement for your mobile carrier. From SCB Tech Solution.
