You may have seen numeric codes (like 272483) used to fetch an app inside the Downloader app. Those aren't official codes from the app developers — they're short-link redirects that individual blogs and marketing sites register themselves, and different sites publish different numbers for the same app that can change or be reassigned at any time.

Because I can't verify who controls a given code or where it currently points, I'm not listing them here. Instead, every row below gives you either the official app store (safest option — Google Play, Apple App Store, Amazon Appstore) or, where an app isn't store-listed, its official developer website to type into Downloader directly.
