For developers
If your open-source app is on 2113 Apps, this page explains what we do with it, how to link to it, and how to ask for a correction.
What we host
We host the release you published, unchanged: the APK from IzzyOnDroid, from F-Droid, or from your project’s GitHub releases. We don’t rebuild, re-sign or repackage it, and we don’t add anything to it.
Before a file goes up, it has to match the hash in the signed repository index, or the hash GitHub publishes for your release asset, and it has to be signed with the expected key. We then record its permissions, CPU types and any tracker code. Each app page shows the file’s SHA-256 and the signer’s certificate fingerprint, so anyone can check their download. The full list of checks is here.
What we write
Every app page is written by hand, from what we measured in your APK and from your own README and documentation. We don’t copy store descriptions, and we don’t claim to have tested an app we haven’t used. Each page is tied to a version, so a new release flags it for review.
Add a badge
If you’d like to point your users to your app’s page here, you can use this badge. Replace your-app.html with the address of your app’s page, which you can find in the app list or the games section. Please link to the page rather than straight to the APK, so people can see the checks before they download.

Corrections, new apps and removal
- Something on your page is wrong or out of date: tell us the page address and what needs fixing.
- An app you’d like us to add: it has to be open source under a licence that allows redistribution, and published through IzzyOnDroid, F-Droid or GitHub releases.
- You’d rather we didn’t host your app: email us from an address connected to the project, and we’ll take the page and the file down.
