BigPic turns one photo into a grid of tiles — then rebuilds it as one big picture. Print it as a seamless poster, or post the tiles to your feed so they reassemble into the full image on your profile grid. WHY BIGPIC • Split any photo into a grid, from 2×2 up to large layouts. • Seamless poster printing that survives the photo lab: every tile prints at the paper's exact size with a trim margin and corner crop marks, so the pieces line up perfectly. • Export a multi-page PDF at true, pixel-accurate size for print shops. • Post-ready grids: save every tile in the right order for an Instagram-style 3×3 that rebuilds your photo. FEATURES • Presets for Square, 4×6, 5×7, 6×8, 8×10, US Letter, A3, A4, and A5 — or set a custom aspect ratio. • Built-in cropping and fine position control. • Live cut-line preview with framing and trim-margin controls. • Share a single tile or all of them at once. PRIVACY BigPic works entirely on your device. No account, no cloud, no data collection — your photos never leave your iPhone. BigPic is free to start. Upgrade to Pro with a one-time purchase to unlock larger grids — no subscription, ever.

Verdict
The clearest difference is ads: BigPic at none against Grid #'s shown. BigPic also leads on update cadence (every 6 days vs every 3 months) and rating (5.0 vs 4.6). Grid #'s advantage is ratings volume (10K vs 1) and iOS requirement (12.0 vs 17.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Grid # sells 1 one-off in-app purchase and BigPic sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
BigPic holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Grid # has 10K ratings behind it against 1, so its average is the more settled of the two.
Grid # ships an update every 3 months, BigPic every 6 days. The most recent releases landed on November 6, 2026 and November 4, 2026 respectively.
