Most questions are answered below. If yours isn't, write directly — a real person reads every message, and you'll usually hear back the same week.
GridMakr is a one-developer indie app. Emails come directly to Dennis in Berlin, get read the same day, and almost always get a reply within a couple of business days.
Instagram orders a carousel by the order you tap the photos in its picker, not by file name. Save the export to Photos, open Instagram, select multiple, and tap slide 1 first, then 2, and so on. The numbers in GridMakr's slide strip are the order.
Pick the same ratio in Instagram that the post was exported in (it asks when you select the first photo) and do not let it re-crop. Every panel leaves GridMakr at exactly 1080 px wide, so with the ratio kept, the seams meet edge to edge.
The picker is Apple's, and it shows what Photos has. A photo that lives only in iCloud can take a moment to download; a photo you deleted in Photos is gone for the picker too. GridMakr has no library access of its own, so there is nothing to grant in Settings.
Expected. A ratio change re-clamps every photo so nothing shows a gap, but it keeps your framing wherever it still fits. Pan and pinch to adjust; double-tap a cell to reset it to fill.
Frames you moved or resized by hand are pinned and survive Shuffle; only the rest are re-hung. Changing the slide count asks first (“Re-hang”). If the wall came out empty, add photos with the + tile on the paper.
GridMakr needs iOS 26. It is built on the Liquid Glass design system, which does not exist on earlier versions. Update in Settings → General → Software Update; any iPhone that runs iOS 26 runs GridMakr.
GridMakr never touches your Instagram account, so the last mile is yours. This is the whole routine; the only rule is to tap the slides in the order the strip shows them.
Stacks, sliced panoramas and galleries in one carousel, a slide strip to add, duplicate, reorder and split, post-wide ratio and frame, numbered 1080 px export.
Leave a post and find it on Home when you come back, exactly as you left it. Stored as copies inside the app, so nothing depends on your library or leaves the phone.
Pick everything first and let the app propose the composition; a Feed / Profile / Swipe preview that shows how the post lands on your grid before you export.
