Pixpipe vs Graincount

Snap your item photos and get clean, marketplace-ready shots in one batch, right on your iPhone. Pixpipe removes the background from your product photos on-device, drops your item onto a clean studio background, squares it up for the listing, and exports the whole batch at once. All on your iPhone, with no per-image credits and no upload wait. BACKGROUND REMOVAL, ON YOUR IPHONE - Lift your item off its background automatically, using Apple's on-device Vision engine - Keep a transparent background with PNG output, or use studio white, neutral, soft gray, a custom color, or a gradient - Add a soft contact shadow so the item sits naturally - Center it on a square canvas with margin, exactly how online marketplaces like it - Fine-tune the cutout with erase and restore brushes before saving - Open Before and After full screen, zoom into details, and switch between images BUILT FOR RESELLERS Whether you resell online or run a small shop, clean backgrounds sell. Pixpipe turns a pile of messy phone photos into a consistent, professional set in minutes, the same look on every listing. ONE BATCH, START TO FINISH - Remove background, clean background, square, optional watermark, rename, export - Batch rename for the listing (SundressBlue_01 to 08) - Export to Photos, Files, share, or a single ZIP for desktop upload - Save your background, watermark, and naming as a one-tap Brand Kit and reuse it every listing day ALSO INCLUDED - Strip EXIF: remove GPS and device info before sharing - Convert between JPEG, PNG, and HEIC - Add a border - Text or logo watermark FREE AND PRO - Free: background removal, white or transparent backgrounds, contact shadow, square framing, touch-up, save/share, and ZIP export, up to 5 photos per batch - Pro: unlimited batch volume, every background style, Brand Kits, batch crop and rename, and text or logo watermarks PRO PRICING - Yearly (7-day free trial for eligible new subscribers) - Lifetime: a one-time purchase, yours forever - Subscriptions auto-renew until canceled; manage or cancel anytime in Settings.

Graincount: Microstructure is a planar grain-size worksheet that keeps a human at the eyepiece. It opens on a labeled synthetic worked example, so the whole workflow is visible before you import anything of your own. Does it segment grains for me? No, and that is deliberate. You import a micrograph as immutable evidence, then place, classify, and weight every intercept crossing or grain tally yourself; the app's job is geometry, arithmetic, and record-keeping, never automated detection. How do my marks become a grain size? A two-point calibration against a feature of known length (nm, um, or mm) fixes the scale. Accepted marks on drawn intercept lines pool into a Heyn-style mean intercept, while counts inside planimetric frames yield grains per square millimetre and an equivalent-circle diameter, with sample standard deviation reported across fields. Will the number survive an audit? Every commit becomes an immutable revision: the snapshot is canonicalized, hashed with SHA-256, and chained to its parent. You can inspect any revision's diff, restore an older one as a new revision, and export the worksheet as a project package, CSV, or PDF that states its own limitations. Everything computes and stays on your own device, and one purchase covers the app for good - no subscription meter running.
