About

PureFrame Live Collage

Every moment, framed with quiet care. The light of morning, a cat in the afternoon, a city glowing at night. PureFrame arranges your photos and videos, nine to a page, into a layout you love — turn pages, add music and subtitles — and saves them as a picture, a video, or a moving Live Photo. Set it as your animated Lock Screen, and each time you wake your phone, a memory turns its page. Everything happens on your iPhone or iPad. No account, no uploads, no internet. No subscription, no in-app purchases, no ads. MADE FOR IPHONE DUO • Unfolded: the controls dock to one side — left or right, your choice — with the canvas on the other, and more room to work. • Folded: the familiar one-hand layout, kept clear of the system's side controls. Pick as many as you like at once — up to 256 per work. A page holds nine and the rest flow onto new pages by themselves. READ IN NOTE · Every saved work opens like an album: turn pages with your finger, using the book’s own effects, while videos keep playing. AUTO LAYOUT · Tap Auto and new photos are arranged by orientation and subject, big to small, with videos in the lead and extra pages when needed. LAYOUT · Free split, hand-drawn frames, freeform frames, Lock Screen layouts, twelve borders. LIVE PHOTO · Twelve entrance effects that settle on your layout, with videos playing inside the frames. PAGE TURNS · Up to 64 pages; book curl, spine turn, push, cover and fade. Each page its own hold time, each turn its own duration. MUSIC & SUBTITLES · Twelve free tracks or your own; several voice clips in order; on-device speech to subtitles you can edit — delete the audio and keep the words. STICKERS & STAMPS · Sixty-four stickers and greetings, text stickers, photo stickers and postage stamps with US-dollar values and postmarks. BLUR, PIXEL & PEN · Hide plates, faces and details, or draw on your photos. AI CAPTION HELPER · Who, what, when, where and things, gathered on your device into a prompt for any AI chat tool. No photo ever leaves your phone. NOTE · A small diary of every export, with layouts you can reuse. DEMOS · Three short films in Help: free dragging, the Deal effect, page turns. Privacy: no data collected. The microphone and speech recognition are used only when you record or create subtitles, and recognition runs on your device.
