Heliograph Universal Airdrop

Send a file straight from your phone to another, with nothing in between. Heliograph moves files device-to-device — over Bluetooth, your local Wi-Fi network, or a flickering QR code the other phone reads with its camera. There's no account to make, no cloud storage involved, and no server anywhere in the middle. Your file goes from one phone to the other, and nowhere else. HOW IT WORKS Open Heliograph on both phones. Pick Send on one and choose a file — Heliograph starts offering it immediately, over everything it has. Pick Receive on the other, and it listens on Bluetooth, Wi-Fi, and camera all at once. Whichever path the two phones can actually reach each other with is the one it uses, automatically — you never have to choose a transport yourself. WHY IT'S DIFFERENT • No account, no sign-up, no server — files move directly between the two devices in the room • Uses whatever's available: Bluetooth, local Wi-Fi, or a flickering QR code read by the other phone's camera • An interrupted transfer resumes where it left off instead of starting over from zero • Works with anything already on your phone — photos, videos, documents HELIOGRAPH PREMIUM Heliograph is free to use, supported by a couple of unobtrusive ads — one when the app opens, one on the home screen. Heliograph Premium ($7/year, auto-renews until cancelled, billed through Google Play) removes both. Manage or cancel the subscription any time from your Google Play account. The same subscription is also what unlocks Heliograph on Mac, where there's no free tier. PERMISSIONS, PLAINLY Camera: reading the flickering QR codes when receiving that way. Photos: letting you choose a file to send. Bluetooth and Wi-Fi: finding the other phone and moving the file between them. Nothing is accessed until you actually use it for that purpose — see the in-app Privacy Policy for the full picture, including what Heliograph's ads involve. Two questions, not four transports: are you giving, or getting?
