Aether is distributed as an APK file and is not available on the Google Play Store. Installation is manual — you download the APK directly from GitHub and install it yourself. This page walks you through everything you need to know.

​
Download

Download the latest APK from the Aether GitHub Releases page. Aether ships two build flavors:
  • Release — Stable builds recommended for everyday use. Published on the Releases page as versioned tags.
  • Nightly — Built automatically from the main branch. Contains the latest features and fixes but may be less stable. Download nightly builds from nightly.link. Nightly builds use different flavor resources (app name, icon) to distinguish them from the stable release.

​
Install steps

1

Allow installation from unknown sources

Go to Settings → Apps → Special app access → Install unknown apps. Find your browser or file manager in the list and enable Allow from this source.
2

Open the downloaded APK

Locate the APK file in your Downloads folder (or wherever your browser saved it) and tap it to open the installer.
3

Tap Install

Tap Install on the Android installer prompt and wait for the installation to complete. The process typically takes a few seconds.
4

Open Aether and complete onboarding

Tap Open once installation finishes (or find Aether in your app drawer). Follow the onboarding flow to grant permissions and configure your first LLM provider.

​
Permissions

Aether requests the following permissions during onboarding or at runtime:
PermissionPurpose
INTERNETAllows Aether to reach LLM provider API endpoints
POST_NOTIFICATIONSSends notifications when agent tasks complete or require your attention
FOREGROUND_SERVICEKeeps agent tasks running in the background while you use other apps
FOREGROUND_SERVICE_DATA_SYNCClassifies the foreground service as a data-sync task (required by Android for background execution)
SCHEDULE_EXACT_ALARMEnables scheduled and time-triggered agent tasks
USE_EXACT_ALARMAllows scheduling exact alarms on devices that restrict SCHEDULE_EXACT_ALARM
RECEIVE_BOOT_COMPLETEDReschedules pending tasks automatically after your device restarts
REQUEST_INSTALL_PACKAGESAllows Aether to prompt you to install extension packages
com.termux.permission.RUN_COMMANDOptional. Required to run commands inside a Termux session for Android shell integration
moe.shizuku.manager.permission.API_V23Optional. Required for Shizuku integration, which enables privileged system operations in Agent Mode
Aether requests only what it needs. Optional permissions are never requested unless you enable the corresponding integration.

​
Optional integrations

​
Termux

Termux is a terminal emulator and Linux environment for Android. When installed alongside Aether, it allows the agent to run commands directly in a Termux session — useful for tasks that benefit from a persistent shell environment or Termux packages. Install Termux from F-Droid (recommended) or the Play Store.

​
Shizuku

Shizuku lets apps use Android system APIs with elevated privileges without requiring a fully rooted device. Enabling Shizuku integration in Aether unlocks Agent Mode’s privileged device automation capabilities — such as installing packages, modifying system settings, and performing other operations that normally require root. Install Shizuku from the Play Store or GitHub Releases.
Aether does not request any storage permissions (READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE, or MANAGE_ALL_FILES). All app data — including your API keys, conversation history, and extension files — is stored exclusively within Aether’s private app directory and is never accessible to other apps.
