Griddify helps you prepare photos for social media. Create profile grids, seamless carousels, collages and images for popular social formats — directly on your iPhone or iPad. PROFILE GRIDS Split one photo across several posts and preview how the finished result will look on a profile. Choose layouts from 3 × 1 through 3 × 6 and follow the clear posting order when exporting. SEAMLESS CAROUSELS Turn a wide photo into a seamless panorama carousel with 2 to 10 pages. Images are divided using pixel-exact boundaries so adjacent pages line up while swiping. You can also combine several individual photos, reorder them and arrange them in one carousel. COLLAGES AND SOCIAL FORMATS Combine several photos into one collage or use ready-made formats for: • Instagram posts • Stories and Reels • Facebook • LinkedIn • YouTube thumbnails and channel art • X headers • Pinterest EDIT YOUR DESIGN • Pan, zoom and rotate photos • Adjust brightness, contrast and other settings • Add a blurred background fill • Add your own text or logo • Display safe-zone guides for Stories and Reels • Use on-device face-aware alignment to help keep cut lines away from faces PLAN YOUR FEED Arrange upcoming posts in a three-column profile preview. Add captions and hashtags, save hashtag groups, reorder posts, mark them as posted and copy your text with one tap. You can also schedule a local reminder for the time you want to publish. Griddify never posts automatically to social media. EXPORT Export high-resolution results to Photos, Files, the share sheet or a ZIP archive.

The clearest difference is in-app purchases: Griddify at none against Rendrl's 2. Griddify also leads on ads (none vs shown). Rendrl's advantage is iOS requirement (16.0 vs 18.0). On price and device support there is nothing between them.
