What apps are on The Ghost Phone? Well, it can take a LONG time digging through various app stores, online reviews and forums to find the best tools and apps available within the world of Free and Open Source Software (FOSS).
As such, we spend time every few months curating a list of applications we feel will get our customers up and running as quickly as possible once they receive the phone.
This list has changed a fair amount since we started offering these phones in November of 2022, as sometimes the apps we used and liked have changed ownership and business practices and sometimes we simply find a better version of something we know you’ll find useful.
If you’d like to learn more about The Ghost Phone, check out our article Getting Started w/ Your Ghost Phone HERE.
If you have suggestions for apps we should have installed that are not listed here, please reach out to [email protected] and we’ll consider the request.

Other Apps Installed on The Ghost Phone
Note: As of November 17, 2025 we have made some significant changes to our pre-installed app selections. To make the process of loading new applications onto the device simpler and faster for both us and you (should you ever need to do this on your own) we now use the Obtainium app for most “core” installations as well as Droid-ify (which replaces F-Droid) and the Aurora app store.
If you’re installing these apps on your own, you’ll need to first install the Obtainium app using the stock Vanadium browser by going here https://mark37.com/ghost-phones/obtainium-latest
Next you will need to configure Obtainium by downloading and importing a file which can be found here https://mark37.com/ghost-phones/obtainium-apps
Clicking on the configuration file link above will download the file to the Downloads folder on your device.
With Obtainium installed and the configuration file downloaded, open Obtainium and tap in the “Import / export” button at the bottom, then tap on “Obtainium import” which will open in the phone’s Downloads location. Find and tap on the select the file named “obtainium-export-2026-02-12T16-17-57.057354.json”. Obtainium is now ready to use.
What is Obtainium?
Obtainium is an Application Manager. Unlike an App Store where you can search for applications you wish to install, Obtainium takes in “definitions” for how an application is installed and handles the installation and future updates for you. We use Obtainium to handle the installation of many of our core applications because it means that we can quickly reproduce a complete “load out” of our base applications on a fresh installation of GrapheneOS.

PRO TIP: WE HIGHLY RECOMMEND YOU UNINSTALL THE APPS YOU DO NOT USE! Give yourself a few weeks to try them all out, and then uninstall those you know you will not be using. This will save storage space, ensure programs are not running in the background that do not need to be, and de-clutter your phone so you can get to what you need quicker.
