# Android app, website and scan packs: what runs where - URL: https://abdohoo.app/help/shadecard/android-app-website-and-scans - Product: Shadecard (https://sc.abdohoo.app) - Section: Getting started - Updated: 2026-09-30 > Measuring happens in the Shadecard Android app. sc.abdohoo.app is the product website with a live demo. A new install has 3 free scans; scan packs come through Google Play. Shadecard's measuring tool is an Android app: the camera capture, the 13,297-shade library, the recipe calculator and your workspace all run on the phone. The website at [sc.abdohoo.app](https://sc.abdohoo.app) explains how the measurement works and has a demo you can click through, but it does not measure cloth. A new install includes three free scans; after that, scan packs are bought through Google Play. ## The Android app The app needs Android 8.0 or newer and a back camera. Most of it works offline: the shade library is bundled with the app, and the capture, matching and calculator run on the phone. When you are online the app also checks for library updates and, if you sign in, keeps a cloud backup. At the time of writing, sc.abdohoo.app lists the Android app as coming soon to Google Play. ## The website: sc.abdohoo.app The website is where you can see what Shadecard does before installing it. It explains the four steps of a measurement (lock, measure, match, mix), the three conditions under which the app refuses a recipe, the library's six families, and the Urdu interface. ![The sc.abdohoo.app landing page with the headline Photograph the cloth, read the color, mix the dye, and the demo instrument showing a Terracotta reading](https://abdohoo.app/media/library/shadecard/web-landing-desktop.webp)sc.abdohoo.app on a desktop browserThe instrument panel on the page is a **demo**: pick a swatch under **Measure another swatch** and it plays through three shots, the fused L\* a\* b\*, the shot agreement, the nearest shade, the match ΔE00 and the depth, using real library shades and the app's own colour maths. It simulates a capture; it does not read your cloth. The page also has an **English / اردو** switch. ![sc.abdohoo.app on a phone in Urdu: اردو selected in the switch, the Urdu headline, the Google Play coming-soon badge and the demo instrument below](https://abdohoo.app/media/library/shadecard/web-urdu-landing-phone.webp)The website on a phone, switched to Urdu## Scans: free, paid and what counts The home screen shows how many scans you have left, for example **3 scans left · Get more**. Tap it (or the **Scan packs** tile) to open **Scans & AI credits**. ![Scans & AI credits screen showing 0 paid scans with AI and 3 free scans without AI, and a Sign in button](https://abdohoo.app/media/library/shadecard/android-scans.webp)Scans & AI credits: your paid and free balanceHow it works, as the app describes it: - **Your first 3 scans are free** (without AI). - After that, buy a **scan pack**. Paid scans include AI analysis. Payment is handled by Google Play. - You must **sign in** to buy scans and to sync them across your devices. - When you have paid scans, they are used first; the free scans apply when the paid balance is zero. A scan is counted only when a **fresh capture produces a result**. These never use a scan: - a capture that is rejected (**Couldn't get a clean reading**) - the torch **light check** on an existing result - reopening a saved measurement from **My workspace** - browsing the **Shade library** or using the **Recipe calculator** If you have no scans left, tapping **Capture dress color** shows **You've used your 3 free scans** with a **See packs** button. ## AI analysis (paid scans) On a result from a paid scan, **Get AI analysis** asks a cloud AI model for a second opinion on the colour and recipe. This sends the measurement's colour values and a small cropped image of the fabric to Shadecard's server, which forwards it to the configured AI provider. If you never tap it, no image leaves the phone. The app's own match and recipe do not depend on it. ## Account and backup Signing in is optional. Without it, the app shows **Not signed in — your data stays on this device only.** With an account, your shades, measurements and dip log back up automatically. See [Saved measurements, export and cloud backup](https://abdohoo.app/help/shadecard/saved-measurements-and-backup). ## Related - [What Shadecard does and who it is for](https://abdohoo.app/help/shadecard/what-is-shadecard) - [Take your first fabric reading](https://abdohoo.app/help/shadecard/first-capture) - [Fix a rejected capture](https://abdohoo.app/help/shadecard/capture-rejected) ## Frequently asked questions ### Can I measure fabric from the website? No. The camera measurement, library, calculator and workspace are in the Android app. The website at sc.abdohoo.app explains the method and includes a demo that simulates a reading. ### Is there an iPhone version? Not at present. Shadecard is built for Android (Android 8.0 or newer). ### What uses up a scan? Only a fresh capture that produces a result. Rejected captures, the torch light check, reopening a saved measurement, the library and the calculator do not use scans. ### Do I need an account? No. Without an account your data stays on the phone. Sign in to back up your recipe book to the cloud and to buy scan packs.
