If you are using GrapheneOS on your main phone, then you have made the first and most important step towards privacy in your daily life (in my opinion of course). Most people use their phones more than any other device, and have their phones on them almost all the time, so ensuring that your phone is as private as you can reasonably and comfortably make it is a great move. Switching the operating system is only the first step however. If you move from an iPhone full of big tech apps to GrapheneOS and then install all those apps again, what is the point? Sure, you will have a more private and secure system, but you would subject yourself to being tracked every time you open an app. So, we need to find alternatives to these apps, that are open source, don't track us, keep everything possible local, and don't have an ulterior agenda beyond being the tool you are looking for.
I have tried MANY local music players, and this is by far the best one that I have used. Handles my 100GB+ FLAC library with no hiccups, downloads lyrics and album covers from the internet when necessary.
You just add your main audiobook folder and every folder in there will be recognised as a single book. That keeps your library simple and tidy.
Very nice audiobook player. Very simple and only does what it needs, but with everything executed amazingly. Sleep timer, many file formats, several options for how you organize the files in your system, etc.
mpvExtended is a fork of mpv-android, built on the libmpv library. It aims to combine the powerful features of mpv with an easy to use interface and additional features.
Best video player I've tried. Has many features, a sleek interface, and is based on MPV. What more do you need?
Step back in time with ClassiPod, a local music player app designed to capture the nostalgic essence of the iconic iPod Classic. Immerse yourself in the familiar click wheel interface and relive the joy of navigating your music library with a touch of retro charm.
Just a fun local music player with an iPod aesthetic. Pretty customizable too. I have an iPod Nano and I have to say, they did a very good job emulating the experience.
Client to access YouTube music. I only use it to listen to tracks to decide if I want to download them or not.
Lightweight and open-source app for YouTube, PeerTube, SoundCloud, and more. No Google Account needed, supports 4K and background audio streaming with downloads.
YouTube front-end. I used to use Tubular, a fork of NewPipe, because it added SponsorBlock, but it would take much longer to adopt updates that get around YouTube's blocking, so I begrudgingly switched back.
A privacy-focused, censorship-resistant multinet Android radio player built with Claude Code. Supports I2P, clearnet and Tor streaming.
Listen to any internet radio streams, even through Tor or I2P. Has a sleep timer, equalizer, can record the radio stream, and more.
A free and open source podcastmanager for Android, allowing you to subscribe to podcasts (via iTunes database & OPML), automatically download episodes using powerful mechanisms and listen to them the way you like (speed, balance adjustments, etc).
I rarely listen to podcasts (audiobooks are preferred), but when I do, I use this app. Lets you stream and download podcasts with a decent interface.
A privacy-first calendar that works offline and looks beautiful. Connect to iCloud — or don't. Your schedule, your choice.
The best local calendar app that I have found so far. The dev cares a lot about user experience and has a Signal group chat where discussions take place. Also has functionality to sync to iCloud calendars, CalDAV, and many other services.
Tasks is libre open-source software, based on the original source code from the popular Astrid Tasks & To Do List! Tasks is easy-to-use, feature-packed, flexible and customizable, and synchronizes with a variety of services.
The best task-tracking app I have ever tried. The UX is great, very intuitive interface, the widgets are some of the best I've seen, and the ease-of-use makes it easier to get myself to keep track of stuff.
Free, open-source, local-first task manager and time tracker for desktop, web, Android and iOS, with Pomodoro focus and optional self-hosted sync.
A very advanced productivity app that functions on "projects." Before I found Tasks.org, I used this to keep track of everything, including schoolwork. However, it's a little too advanced for my needs, so I haven't been using it recently.
Minimalistic pomodoro timer with a lot of customization.
Get fit with Flexify. Easily track your gym progression with offline records and seamless graphs.
Make workout routines and track them. You can also track your weight with a progress picture if you want. I don't track calories, but the same author behind this app also made a very nice calorie tracking app, "FitBook."
RunnerUp - A open source run tracker inspired by Garmin 410, 
ASICS Runkeeper and EveryWhere Run.
Run tracker with many stats and metrics for you to look at, and helps you guide your runs.
The default launcher is nice, but lacks many features.
Open-source Android launcher with customizable icons, layout, and integration of Google Feed, offering Pixel Launcher features without root access.
This is very similar to the default launcher, but adds many features like changing the app icons and their size.
Minimalist Android launcher enabling instant search through apps, contacts, and settings, learns usage patterns, works offline, preserves privacy, and saves resources.
This one is super out of the way and just does what you need.
An Android launcher for people who want a simpler, cleaner default experience, focusing on fast access to time, weather, and core apps, with minimal visual noise.
Out of all the minimalist and distraction-free focused launchers, this is my favorite.
My favorite self-custodial mobile wallet. I use it for XMR and to keep track of other crypto that I use to exchange USD to XMR.
Haveno-reto is the flagship instance of Haveno, the non-custodial, decentralized exchange platform for crypto and fiat currencies built on Tor and Monero. It doesn't get more private than that.
P2P currency exchange with arbitrators. Great way to get Monero.
I hope you found some use out of this list! I noticed that a lot of people hear, "Switch to GrapheneOS! Switch to GrapheneOS! It will improve your privacy!" and they do so, but then they are lost when it comes to what apps to use. For a beginner, it can be difficult to discover alternatives to big-tech apps that they have become accustomed to. If you have any suggestions, be sure to leave a comment and I will try them out. I only included apps that I personally use to avoid this list becoming me just listing every app out there.
No comments so far, maybe you want to be first?
