Instalar Aster Mail en tus dispositivos

Install Aster Mail on your computer and phone, and keep the desktop app up to date.

Every app opens the same encrypted mailbox. All downloads are on astermail.org/download, and the web app runs at app.astermail.org with no install.

Before you begin

• Create your account first. See Create an Aster account.
• On Linux, check whether your computer uses an x86_64 or ARM64 processor. Each has its own build.
• To sign in to the desktop app, you need a browser where you can sign in to Aster.

Windows, macOS, and Linux

1. On astermail.org/download, download the file for your system:

   System	File
   Windows 10 and later	The .exe installer or the .msi package
   macOS	The .dmg disk image
   Linux (x86_64 or ARM64)	An AppImage, a .deb package, or an .rpm package

2. Install the app:

   • On Windows, run the installer.
   • On macOS, open the .dmg file and drag Aster Mail to your Applications folder.
   • On Linux, install the .deb or .rpm package, or make the AppImage executable and run it.

3. Open the app and sign in with a device code. See Sign in to Aster Mail.

Update the desktop app

When a banner shows “Aster Mail version is available,” select Install now, or select Later.

To check for updates yourself:

1. Go to Settings > Help > Updates.
2. Select Check for updates.
3. If an update is available, select Install and restart.

To stop automatic checks, turn off Check for updates automatically. To see what changed, select Release notes.

Android

Install Aster Mail from Google Play, from F-Droid, or as an APK:

• On the download page, select Get it on Google Play. For the other options, select Download APK instead or Get it on F-Droid.
• In the F-Droid app, search for Aster Mail.

Google Play and F-Droid update the app for you. If you installed the APK, download the new APK from the same page to update.

iPhone and iPad

The iOS app is in beta through Apple TestFlight. On the download page, select Join the TestFlight beta, and then select Continue to TestFlight. Expect some rough edges while it’s in testing.

You can also add the web app to your Home Screen: open app.astermail.org in Safari, and then select Share > Add to Home Screen.

Other mail apps

To use Aster in a desktop mail app over IMAP and SMTP, install Aster Bridge. Bridge is included with Star and higher plans and runs on Windows, macOS, and Linux. It keeps your keys on your computer and gives your mail app a local account. See App passwords for other clients.

Troubleshooting

• An update doesn’t install: try again from Settings > Help > Updates. If it still fails, download the latest version and install it over the current one.
• The desktop app doesn’t finish signing in: the code may have expired. Select Get new code.
• The APK won’t install: in your Android settings, let your browser or file manager install unknown apps, and then open the file again.
• The AppImage doesn’t start: mark the file as executable, and check that it matches your processor.
