Just as I discovered some really cool apps for Linux, the case has been the same for FOSS Android apps. There were many that took me by surprise, and some that disappointed me as I used them more.
As 2024 comes to a close, it’s a great time to look back on some wonderful open source Android apps that stood out this year. From security-focused apps to general-purpose apps such as keyboards and downloaders, we had plenty that piqued our attention.
Let’s kick things off! 😎

These Are The Most Useful Linux Apps I Discovered in 2024
Here are the best Linux apps we encountered in 2024. Try them out if you haven’t yet!
1. Exodus
⭐ Key Highlights:
- Regularly Updated
- Data Collection Insights
- App Permissions Analysis
We begin with Exodus, an Android app that helps track which apps are employing what kind of trackers, allowing users to deep dive into each app’s tracker details. It shows helpful insights on potential privacy risks, enabling anyone to make an informed decision about the apps they install.
All of that is made possible due to the εxodus privacy auditing platform that lies underneath, checking for app behavior like ads, tracking, and analytics that could affect a user’s privacy.
2. Simple Keyboard
⭐ Key Highlights:
- Minimal Interface
- Highly Customizable
- No User Data Collection
This is a personal favorite of mine. Simple Keyboard is a minimal open source keyboard app that doesn’t collect user data or implement trackers. It offers plenty of useful features like auto-capitalization, customizable themes, changeable keyboard height, and more.
It is designed to be a no-nonsense, lightweight keyboard app that doesn’t get in the way. You can learn more here:

3. Currencies
⭐ Key Highlights:
- No Ads/Tracking
- Easy-to-Use Interface
- Multiple Data Providers
If you are traveling abroad or are just curious what your next purchase would cost if you were to import it from some foreign marketplace, an app like Currencies is what you are looking for.
Thanks to its regularly updated data sources, you can search for currency exchange rates on the go by using its clean, user-friendly interface. You can even add your favorite currencies so that you don’t have to search for those each time you open the app.
4. Password Monitor
⭐ Key Highlights:
- Minimal User Interface
- Gives Helpful Suggestions
- Supports Incognito Keyboard
In an age of constant cybersecurity threats, having secure passwords is a crucial thing. Sure, you can use password managers on desktop, but keeping track of any compromised passwords is just as important.
Password Monitor can help you do that. From the developer of IYPS, it is an open source password checker tool that has tight integration with Have I Been Pwned?, allowing the app to search through a global database of compromised passwords.
5. Ente Auth
⭐ Key Highlights:
- Runs Offline
- Cross-Platform
- Optional Cloud Backup
From the house of Ente, the Ente Auth app is a free, open source authentication tool for Android (and other platforms) that has been designed as a privacy-focused alternative to the likes of Authy. It features end-to-end encryption, can show a user the next authentication code for ease of use, and can be integrated with a smartphone’s screen lock (biometric/conventional).

6. Seal
⭐ Key Highlights:
- Fast Downloads
- Supports Many Platforms
- Reliable Download Management
Ever felt the need to download that spicy Arch Linux meme on YouTube, but couldn’t because you would have to sign up for a paid subscription? Well, then you can use Seal, a Kotlin-based app that is powered by yt-dlp.
It features customizable options for video quality, audio formats, and subtitle downloads. Just keep in mind that it can only handle one video at a time.
Seal also supports other platforms that yt-dlp does, so you can download content from Facebook, Instagram, TikTok, and many others.
7. Hacki
⭐ Key Highlights:
- Has Offline Mode
- Highly Customizable
- Many Engagement Tools
If you are a regular on Hacker News, then you should definitely check out Hacki. It is a feature-rich, open source client that supports logging into a Hacker News account, allowing access to many features like voting, commenting, saving, etc.
It is cool to see someone develop such a client, as the Hacker News platform is a popular choice among tech professionals, developers, and startup founders. Having a mobile app (even an unofficial one) just makes it easier for people to interact with each other.
8. NetGuard
⭐ Key Highlights:
- No Root Required
- Intuitive Interface
- Allows Granular Control
We culminate this roundup with NetGuard, an open source Android firewall app that can block internet access for specific apps without requiring root access. It offers functions like network access toggles, traffic logs, and advanced rules, enabling high levels of privacy and data usage control.
