6 free and open-source apps I install on every Android phone

• KeePassDX
• LocalSend
• PixelPlayer
• Cromite
• Rain
• Fossify

As a general rule of thumb, I’m happy to spend money on an application or piece of software, so long as it’s well-crafted, from a reputable source, and functionally compelling. I didn’t think twice before purchasing this $5 iPad keyboard, for example, and the $20 I dropped on this macOS screensaver is cash well spent in my books.

Of course, it’s not always necessary to part ways with your dollar bills when shopping around for new and exciting applications, and this is especially true when it comes to software built for Android. In fact, there’s a whole genre of free and open-source (FOSS) mobile apps for Android that provide excellent functionality, all without costing a single cent, and all while offering transparent code sources.

Here are six FOSS applications for Android that I always install on day one, and that I can’t see myself going without anytime soon. Some of these apps can be downloaded and installed directly from the Google Play Store, while others are available exclusively via alternative sources like F-Droid or GitHub.

For more information on how to download and install Android applications from outside the Google Play Store, check out my dedicated article on the subject right here on Pocket-lint.

KeePassDX

A FOSS password manager

KeePassDX is a rather excellent FOSS password and passkey manager, with all the essentials you’d expect to find being present and accounted for, including biometric authentication, autofill support, URL field copying, and offline compatibility. The app also works as an authenticator, with options for one-time password management, as well as two-factor authentication (2FA). KeePassDX has a slick user interface, and, in my experience, it’s a dependable choice with a welcome emphasis placed on security and privacy.

LocalSend

A FOSS wireless transfer tool

While it’s true that interoperability between Google’s Quick Share protocol and Apple’s AirDrop protocol is improving, I still find that, on the whole, both standards suffer from dropped connections, slow performance, and a lack of reliability. That’s where LocalSend comes into play: it’s a FOSS alternative that somehow works faster and more effectively than any other market solution I’ve tried, all while working on just about any platform or operating system. LocalSend’s UI is simple but purposeful, and I love the added charm of the default device naming conventions used.

PixelPlayer

A FOSS local music player

I’ve written about several Android-based local music player apps in the past, and the ecosystem of options has only continued to grow since then. One newer FOSS option, which is still in its development phase, is PixelPlayer. The app looks and feels like the sort of offline MP3 app that Google would’ve made in an alternative timeline, with a full embrace of Material 3 Expressive design language principles, dynamic color theming, and several other niceties that all make for a delightful end-user experience.

Cromite

A FOSS web browser

Cromite is a branched version of the once-popular Bromite, a FOSS take on Google Chrome that cuts out the corporate baggage in favor of a clean and lean experience. Cromite builds upon this foundation, making it an excellent Chromium-based Android web browser for anyone not enthused by Google’s various privacy-obstructing tendencies. The app’s design is familiar, sharing common DNA with mobile Chrome itself, but with added support for ad-blocking, anti-fingerprinting mitigation, and more.

Rain

A FOSS weather forecaster

There are plenty of excellent FOSS weather applications available for Android, including the legendary Breezy Weather. Personally, my go-to at the moment is Rain, which features a gorgeous user interface design, cute anthropomorphic weather status icons, comprehensive forecasts, and a tab dedicated to viewing the current weather in any number of cities or locations. Rain is slick and speedy, offers localization in several languages, and provides granular details on current and hourly weather conditions.

Fossify

A FOSS file browser

As far as FOSS file managers go, Fossify ranks among my favorites. It’s not intrusive in its permission requests, it allows for biometric lock-down of files and folders, it has built-in compression tools, and it’s customizable from a user interface perspective. The overall look and feel of Fossify is solid, with a clean design that puts your local files front and center. It’s certainly a more full-featured package than, say, Files by Google, and I therefore much prefer Fossify when operating within Android’s recently-released desktop mode on my Pixel 10.
