Like a walkie talkie, but for texts. Two iPhones, a seat apart on a plane, a tent apart at the campsite or a wall apart at home, share one private room over Bluetooth. No internet, no signal, no account. Gridless is made for exactly two people who already know each other: partners, parent and kid, best friends, travel buddies. You both install it, meet once, scan a QR code, and your iPhones open an end-to-end encrypted room. Within Bluetooth range, messages go straight to the other phone, and when you are near each other again, opening Gridless on either phone brings the room back. 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 the crowd swamps the towers - At the campsite, the cabin, the cruise, the blackout - Abroad together, with no data plan between you - On a kid's hand-me-down iPhone with no plan - At home, when what you two say is nobody's business but yours ONLY YOU TWO CAN READ IT - Every message is end-to-end encrypted between your two phones (Noise protocol), and 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 go phone to phone: compressed, stripped of location, never uploaded anywhere ONE ROOM, TWO PEOPLE No group chats to mute, no strangers' phones relaying your words, nothing broadcast to a crowd. A private line: one scan to set up, nothing to manage. LOCKED ON THE PHONE TOO - Your history sits behind Face ID or a passcode, plus a passphrase - Delete all data: one tap, permanent. The other phone keeps its own copy IT LIVES IN YOUR POCKET - In range, messages keep landing, with notifications, for days at a time - Apart, your words wait on your phone and deliver the moment you are back together - After hours or even days apart, opening either phone reconnects the room, even while the other one stays locked in a pocket. Just leave Gridless in the background rather than swiping it closed 20 LANGUAGES Gridless follows your phone's language, or pick one in Settings > Language. FREE TO TRY Your first 3 days are free on both phones, with everything unlocked. After that, reading and receiving stay free, and unlimited sending is Gridless Pro: yearly (with a 7-day free trial), monthly, or a one-time lifetime purchase. One of you goes Pro, and both of you get it. Some conversations don't need the whole internet. Just the person down the hall.
