App Asset Size Inspector

App Asset Size Inspector is a private, fully offline utility for checking graphic asset sizes, aspect ratios, and safe areas — and for building copy-ready preparation checklists for mobile app graphics.

Type in width and height. Instantly see whether your asset fits a preset, how close the ratio is, and what to adjust before you publish.

No images. No uploads. No accounts. No permissions. Everything stays on your device.


WHAT YOU CAN DO

• Size Check Studio — Enter dimensions, pick a preset and platform, and get a clear result: Perfect Match, Fits, Close Match, Too Wide, Too Tall, Wrong Ratio, and more — with crop, fit, and resize suggestions.

• Preset Gallery — 15 built-in presets across icons, feature graphics, backgrounds, banners, screenshots, splash screens, and more. Search, filter, favorite, and jump straight into a size check.

• Safe Area Preview — Visualize safe, risky, and center zones on any canvas. See whether your object fits inside the safe area before you finalize artwork.

• Ratio Compare — Simplify any ratio, find the closest known match (1:1, 16:9, 9:16, 4:3, and more), and discover which presets may fit.

• PX / DP Calculator — Convert between pixels and density-independent units across mdpi through xxxhdpi, with a clear scale readout.

• Checklist Builder — Build a copy-ready asset prep checklist by asset type and platform (safe area, ratio, transparent background, naming, and more).

• Saved Checks & Stats — Keep a local history of inspections, copy results and checklists, and review your usage insights — all on-device.


BUILT FOR PRIVACY

• 100% offline — works with no internet
• Zero permissions — no storage, camera, or network access
• Manual input only — you enter the numbers; the app never imports or scans images
• Local storage only — saved checks, presets, and settings stay on your phone


WHO IT’S FOR

Designers, developers, QA, and store-listing editors who need a fast, private desk for checking asset dimensions and ratios — without sending files anywhere.


IMPORTANT

Results are based on the dimensions you enter. Always review current platform requirements before publishing. This app does not guarantee app store approval.
