This page contains some Frequently Asked Questions.

What is AsteroidOS?

AsteroidOS is an open source Linux distribution that runs on many different smartwatches. It uses Qt and QML to provide the graphical interface.

Is AsteroidOS based on Android?

No. AsteroidOS uses libhybris to simplify porting to most Android and WearOS watches, but it is not Android nor is it WearOS or a derivative of either.

Can I run WearOS applications?

No. WearOS is a version of Android that runs on wearable devices. AsteroidOS is a Linux distribution that does not run Android and therefore cannot run either Android or WearOS applications.

What are the differences between AsteroidOS and WearOS?

One significant difference is that AsteroidOS is open source software, while WearOS is not. This means that if you would like to change something, and you are a developer, you can build the software yourself. Or perhaps you would like to create your own watchface. Another significant difference is that unlike WearOS, AsteroidOS tries to make the watch useful even without pairing it with a phone. By contrast, WearOS watches won't even start running until they are paired with a phone.

Does AsteroidOS have any tracking features?

No. AsteroidOS does not collect any tracking data and you don't need to use or establish any accounts to use it. Nothing on the default installation is able to connect to the internet. While it is possible to connect an AsteroidOS watch to the internet this must be explicitly done by the user.

Can I run AsteroidOS on my watch?

Maybe. Check the Install page to see if your watch is listed.

Which features of my watch are currently supported by AsteroidOS?

Check the features table to see all of the watches and which features they support.

My watch isn't listed. Can I still run AsteroidOS?

Maybe in the future. See the porting status page for details on what kinds of watches might be supported in the future and what the general requirements are for running AsteroidOS.

Will I be able to revert to the previous operating system after installing AsteroidOS on my watch?

Yes, if you choose the "temporary install" option. See the installation FAQ for details.

Where can I find a phone synchronization app?

A phone is not required to use AsteroidOS, but several convenient functions are available when an AsteroidOS watch is paired with a synchronization client. For Android phones, "AsteroidOSSync" is available for download on F-Droid. Ubuntu Touch users can download "Telescope" from OpenStore. There is currently no app for iPhone, however notifications can be shared from an iPhone to the watch. See this page for details.

What features and apps does AsteroidOS provide?

Since version 1.0, AsteroidOS has had phone notifications, an agenda, an alarm clock, a calculator, a music remote control, settings customizations, a stopwatch, a timer, and a weather forecast app. Since then, we have also added a game, a flashlight app, a heartrate checking app and many more watchfaces.

What features and apps does AsteroidOS currently not provide?

There are a great many more ideas for apps than apps at the moment. Some of the more commonly requested, but not yet available applications and features are:

  • fitness tracking application
  • step counter
  • ongoing heartrate monitor
  • call answering from the watch
  • support for using the watch as a phone (for some watches that incorporate a cellular phone chip)
  • and many more

Some of these are being worked on, and others are just ideas at this point. If you think you might like to contribute, see our GitHub repository and the Contact page. There are many opportunities for creativity!

Is there something like a "Play Store" to download apps?

Not yet, but this is something that is being considered for future implementation. There are a number of contributed apps that are not installed in the default image. These can be installed manually if desired.

What if my question isn't answered here?

There are many additional resources. The Documentation page should be your first stop. It has a lot of useful information about both using and developing for AsteroidOS. If you can't find your answer on this web site, see Contact.
