Amazon Underground is Amazon's app and game store for Android, built around the old "Actually Free" program that handed out paid apps, games, and in-app items at no cost. This page covers the latest APK release with screenshots, the main features, install steps, compatibility notes, and what to check before you install.

What is Amazon Underground?

Amazon Underground is an Android app store from Amazon. It started as a way to get apps and games that normally cost money for free, with developers paid by Amazon based on how long people used their titles. You install it like any other store, browse the catalog, and download what you want straight to your phone.

This is the original Amazon build, not a modified one. It runs as a normal app: open it, find an app or game, install it, and you are done. Amazon wound down the "Actually Free" side of the program in 2017 and folded the catalog back into the regular Amazon Appstore, so newer installs route you to Amazon's main store.

Your Amazon account, purchase history, and library all work the same way they do in the standard Amazon Appstore. Underground was a front end on top of Amazon's store, not a separate service, so signing in pulls in everything tied to your account.

What does Amazon Underground offer?

Amazon Underground's draw was its catalog of free apps and games. Titles that cost money on other stores, plus a chunk of their in-app purchases, were offered at no charge, with Amazon covering the cost on the back end.

It signs in with your Amazon account, so anything you grab lands in your Amazon library and syncs across your devices. The store hooks into the rest of your Android setup the way any app store does, handling installs, updates, and downloads through its own client.

Browsing is built around games and apps for phones and tablets, with the usual categories, charts, and search. Because it is an Amazon product, it ties into Amazon Coins and account-wide purchases rather than Google Play billing.

Key features

Amazon Underground carries the same store front you would expect from Amazon. Here is what people actually use it for:

  • Free apps and games: The catalog of paid titles offered at no cost, the program's main draw.
  • Quick install: Download and install apps straight from the store client.
  • Amazon account sync: Your library and purchases follow your Amazon login across devices.
  • Amazon Coins: Spend Coins on apps and in-app items where supported.
  • Light footprint: Modest install size and low background use for a store app.
  • Android-native interface: A clean store layout that fits in on Android.

What's new in the latest version?

The latest build of Amazon Underground (v16.21.0.200) sticks to stability, compatibility, and small interface fixes. Amazon has long since merged Underground back into its main Appstore client, so recent builds mostly carry the same store engine that powers the standard Amazon Appstore.

  • Improved stability across newer Android versions, including Android 14 and 15
  • Faster loading and a smaller memory footprint on lower-RAM devices
  • Bug fixes for reported download, sign-in, and update issues
  • Updated store interface that matches Amazon's current Appstore design
  • Better support for foldable and tablet screens
  • Backend changes to keep the catalog and account sync working

Pros and cons

What works
  • All Premium features
  • Ad-free interface
  • No upsell prompts
  • Cloud sync intact
  • Export without watermarks
  • Free to install
What does not
  • Not on Google Play
  • No automatic updates
  • Sideload only
  • Some features may need an account
  • Subscription tier may still appear in UI
  • Permissions require manual review

Good to know before installing

This APK installs by sideload, so Android will ask you to allow 'Install unknown apps' for your file manager or browser. That is normal for any store you install outside Google Play. Only turn it on for sources you trust.

Check the package name, version, and requested permissions before you open the app. An app store asks for broad install permissions by design, but if anything looks off compared to Amazon's official listing, hold off.

Is Amazon Underground safe?

Amazon Underground is safest when you grab it from Amazon's official source or the Amazon Appstore listing. APK files from unknown mirrors can be outdated, altered, or unsafe. Before installing, check the package name, version, file size, and requested permissions. If anything looks different from Amazon's official listing, do not install the APK.

This is the original Amazon Underground client, signed by Amazon rather than a modder. Google Play Protect may still warn you on install because the file did not come from Google Play. That warning shows up for any sideloaded APK; you can read it and proceed at your own discretion. The real question is what is inside the file, which is why we list the package name, version number, and file size up top.

FAQ

  • Is Amazon Underground free?
    Yes. The app is free to install, and its whole point was offering paid apps and games at no cost.
  • Will my purchases sync between devices?
    Yes. Sign in with your Amazon account and your library follows you. Check Settings after install.
  • Can I install Amazon Underground without Google Play?
    Yes. Sideload it through your file manager after enabling 'Install unknown apps'.
  • Does Amazon Underground update automatically?
    No. Pull a fresh build from this page when a new version drops.
  • Does Amazon Underground need root?
    No. It installs as a normal user app by sideload.
  • What Android version does it require?
    Android 5.0 (Lollipop) or later for the latest builds.

Final verdict

Amazon Underground is worth a look if you are already in Amazon's ecosystem and want its app store on Android without Google Play. The "Actually Free" deals have wound down, so treat it as Amazon's Appstore client more than a source of free paid apps. Check compatibility, permissions, and the download source before installing, and pull a new build from this page when one drops.

For your primary phone, Amazon's own Appstore listing is the safer install path, since it gets Amazon's updates and account support directly. If you sideload this APK, get it from a source you trust and keep an eye on the version and permissions. When in doubt, grab Amazon Underground from Amazon's official store instead of a third-party mirror.
