Beautiful Open Source Apps for Android (nice & modern UI/UX)

UI = User Interface UX = User eXperience Most open source apps offer out-dated or classic material design UI. If the apps works great and the UX is not terrible you might find it okay. But intuitive UI are better, and modern looking ones are pleasant to use, sadly they are not the majority. Here is my list of Beautiful Open Source Apps for your android device ! Apps are listed in alphabetical order ! Also look at : The ultimate F-Droid setup for more open source android apps. and Beautiful Open Source Apps for iOS for your iOS device DISCLAIMERS Nice UI comes to personnal preference. So this list is only based on my taste of what is a good modern looking app. While open source is great for privacy and security it is not perfect. So keep that in mind before downloading any apps. I again encourage you to do your own research about them and read their Privacy Policies. I am not a privacy and security expert. I'm also don't consider myself as a developper so I do not have any technical knowledge and so I didn't look into any source code of any apps in this list !

GrapheneOS Starterpack

A list of apps I use on GrapheneOS, but most also make sense on other operating systems. Install "F-Droid Basic" and Obtainium, add a few repos to F-Droid by searching for "F-Droid known repositories"

What is PaperKnife?

Why I built this Most PDF websites ask you to upload your sensitive documents—bank statements, IDs, contracts—to their servers. Even if they promise to delete them, your data still leaves your device and travels across the internet.

I built PaperKnife to solve this. It's a collection of tools that run entirely in your browser or on your phone. Your files never leave your memory, they aren't stored in any database, and no server ever sees them. It works 100% offline.

What it can do Modify: Merge multiple files, split pages, rotate, and rearrange. Optimize: Reduce file size with different quality presets. Secure: Encrypt files with passwords or remove them locally. Convert: Convert between PDF and images (JPG/PNG) or plain text. Sign: Add an electronic signature to your documents safely. Sanitize: Deep clean metadata (like Author or Producer) to keep your files anonymous.
