Two iPhones. One private room. No internet, no signal, no account. Free to try. Gridless is an offline messenger for exactly two people. Meet once, scan a QR code, and your phones share an end-to-end encrypted room over Bluetooth. Come near each other again and the room reopens, ready to text and send photos with no network at all. OFFLINE, ON PURPOSE - On the plane, across the aisle, everything in airplane mode - On the subway, deep below the last bar of signal - At the festival, when a hundred thousand phones swamp the towers - At the campsite, the cabin, the cruise, the blackout - Abroad together, with no data plan between you - At home, when what you two say is nobody's business but yours ONLY YOU TWO CAN READ IT - Every message is encrypted between your two phones. The keys exist nowhere else - No servers, no cloud. Nothing is stored in the middle, because there is no middle - No account, no phone number, no email. App Privacy: Data Not Collected - Compare your safety number in person to confirm no one is between you - Photos are compressed, stripped of location, and never uploaded anywhere LOCKED ON THE PHONE TOO - Your history sits behind Face ID or a passcode, plus a passphrase - Delete all data: one tap, permanent HOW NEAR IS NEAR Bluetooth reaches about a room or two, and walls matter, so this is for the person beside you, not across town. Out of range, your words wait on your phone and deliver the moment you are back together. In range, messages keep landing in your pocket, with notifications, for days at a time. Fully close the app and the room ends until you reopen it. FREE TO TRY Pair with anyone and use the whole app together, free.
