Gridlace — designed templates, seamless carousels, grids, video splits & collages. Start from a designed template, or turn one photo (or video) into scroll-stopping posts. Gridlace helps your feed look intentional — no design skills required, and everything happens right on your device. DESIGNED TEMPLATES Pick from a growing library of ready-made carousel templates — value posts, quotes, listicles, aesthetic packs, promos and Stories. Drop in your words and photos, switch themes, fonts and colors, then export a polished, ready-to-post carousel in minutes. New templates added regularly. THE SEAMLESS CAROUSEL Slice one wide photo into swipe-through slides. Post them as a single carousel and swiping reveals the whole scene as one continuous panorama. Choose 1:1, 4:5, 3:4 or 9:16, reorder slides, and use Seam Guides so faces and text never get cut across the split. COHESIVE CAROUSEL Drop in several separate photos and give them all the same frame — matching border, background and filter — so an ordinary set of shots posts as one cohesive, designed carousel. 3-WIDE FEED PUZZLE (GRID SPLIT) Split a photo into a 3-wide grid that reassembles into one big image across your profile. Gridlace numbers every tile in the exact order to post them — no guesswork. VIDEO SPLIT Split a video into a seamless carousel of video clips. Frame it once and export each slide as its own clip, ready to post in order. BEAUTIFUL COLLAGES Dozens of layouts, freeform arrange (drag, resize, rotate), photo frames, shaped cells, gradient/scene/photo backgrounds, per-photo adjustments, text & stickers — plus on-device background cutout to drop your subject onto any backdrop. MAKE IT YOURS Premium fonts, theme palettes, and a Brand Kit — save your handle, colors, font and logo once and apply them to any template in a single tap, so every post stays on-brand. WHY GRIDLACE • Private by design — your photos and videos are edited entirely on your device and never uploaded to a server. • No ads, ever. • Fast, native, and works offline. • Built-in stock library and sample photos to try instantly. GRIDLACE PRO The carousel, grid and collage tools are free to use. Upgrade to Pro to unlock the full template library, every premium font, the Brand Kit, Video Split, on-device background cutout, every frame and stock photo, unlimited slides and saved projects, highest-resolution exports — and to remove the Gridlace watermark. Pro is available as an auto-renewing subscription (Pro Monthly and Pro Yearly) or a one-time Pro Lifetime purchase. Prices are shown in the app and on the App Store. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours before the period ends. You can manage or cancel subscriptions in Settings ▸ [your name] ▸ Subscriptions. Any unused portion of a free trial is forfeited when you purchase a subscription.
