A fork of the official Mastodon Android app adding important features that are missing in the official app and possibly won’t ever be implemented, such as the federated timeline, unlisted posting and an image description viewer.

Key features

Unlisted posting

Allows you to post publicly without having your post show up in trends, hashtags or public timelines (i.e., in the tabs “Community”, “Federated” and “Posts”).

When posting with Unlisted visibility, your posts will still be publicly accessible in your profile. They will also be shown in people’s Home timelines, but only if they follow you or someone they follow reblogged/replied to your post.

The Mastodon documentation has some more information about Unlisted posting and Public timelines.

Federated timeline

This allows you to chronologically see all Public posts from people on all other Fediverse neighborhoods your home instance is connected to.

Despite being one of the main features of federated social media, the Federated timeline wasn’t included in the official Mastodon app – supposedly, because this conflicts with Google’s safety requirements for apps on the Play Store.

That’s one of the reasons why choosing a small, well-moderated instance is important. Instance admins and moderators should always make sure to ban abusive users and stop federating with instances who platform them. On well-moderated instances, the Federated timeline can be a welcoming place to meet new people!

Draft and schedule posts

Allows for preparing a post and scheduling it to send it automatically at a specific time.

You can create drafts, edit them, send them manually later or set a scheduled date. Drafts are technically saved as scheduled posts, so you can view and edit them from other apps that support scheduled posts. Scheduled posts are handled by your home instance, so they’ll work even if you uninstall Megalodon.

Image description viewer

Allows you to quickly check whether an image or video has an alternative text attached to it.

This is important to ensure the content you’re sharing is as accessible as possible to people who can’t see the images and rely on software to read back the provided content descriptions. Thankfully, it’s quite common for people on the Fediverse to provide such alt texts, and hopefully things stay this way!

Pinning posts

This lets you can highlight important posts on your profile. A dedicated “Pinned” tab in people’s profiles shows all the posts they pinned.

On the Fediverse, it’s quite common for people to pin posts they want others to read before following them. You can pin/unpin posts yourself by clicking the button in the top right corner of your posts.

Note that you’ll need to add Izzy’s F-Droid repository to your F-Droid app first:

Google Play Store

F-Droid Not yet, sorry!

If you want, you can help me figure out if something’s missing in the Issue #47:


Press the download button to download the APK. Open the downloaded file on your Android device to install it. Megalodon will automatically notify you about new updates inside the app.

Download latest release

You might have to accept installing APK files from your browser when trying to install it. You can also take a look at all releases on the Releases page.

Megalodon makes use of Mastodon for Android’s automatic update checker. Megalodon will check for new updates available on GitHub and offer to download and install them. You can also manually press “Check for updates” at the bottom of the settings page!

Release variants

All downloads can be found on the Releases page.


Variant with an integrated updater. If you download Megalodon from here (and not from an app store), just download the regular megalodon.apk.


This is an unmodified version of the official Mastodon for Android app the respective Megalodon release is based on. Should you find any bugs in Megalodon (which you will), try to see if it occurs with this variant, too. The last 7 digits of the file name are important to know which version of the official app you’re using.



As with the source code, the translation is sourced from the official project, which you can contribute to on the official “Mastodon for Android” Crowdin project:

There’s also a handful of custom strings exclusive to this projects that would need to be translated. You can help translate Megalodon on Weblate:

Detailed changes





As this app is using Java 17 features, you need JDK 17 or newer to build it. Other than that, everything is pretty standard. You can either import the project into Android Studio and build it from there, or run the following command in the project directory:

./gradlew assembleRelease
