Duo Tape turns two iPhones taped together into one seamless screen — no cables, no internet, no account. HOW IT WORKS • Place two iPhones flush together, like folding one phone in half • Each phone picks its own side: left or right • Swipe on either phone — content flows across both screens FEATURES • Split photos — pick a photo from your library and it splits automatically across both screens, like one continuous picture • Read together — open a PDF and each phone shows one page, just like holding a real open book • Private messaging — chat between the two phones, even offline; messages that couldn't send retry automatically once reconnected COMPLETELY PRIVATE Duo Tape connects the two phones directly over local Bluetooth/WiFi — no server, no account, no data collection. Everything stays on your two devices. Great for two people sitting side by side who want to share one piece of content, or just for trying out the "folding phone" feeling your own way.
