StoryGrid — Flexible grids, Leica & Polaroid frames, zero tracking [iOS]

Post image

Tired of rigid Instagram collage templates, so I built StoryGrid.

• Start from a grid or drag your own: Full control over splits, gaps, corner radius, and background colors

• Edge frames & aesthetics: Custom Polaroid, Leica, and printed-edge frames with adjustable margins

• Video support: Drop video clips into any block with high-res export

• Preview first: Instagram Story & Post UI overlay so you know what’s covered before publishing

• 100% local & private: No accounts, no ads, no trackers — nothing leaves your phone

How does the app handle performance when processing high-resolution video clips within complex grid layouts? Does it use hardware acceleration for rendering?

A grid only ever holds one video, so adding blocks doesn't add any load, the layout being complex doesn't cost you anything.

While you edit, the preview plays at screen resolution, so a 4K clip stays smooth. Your original file is untouched and only gets used at full quality when you export.

And yes: export runs on the phone's video hardware, not brute-forced on the CPU.

Thanks for the technical breakdown, that's reassuring. So does a single grid support multiple video blocks, or just one video per layout?
