40 Best Free And Open Source Android Apps in 2023

Hey there, you might be wondering what are the best free and open-source Android apps alternatives to most of the applications and services available on your Android-powered device. As you know already, Android development is under the control of Google – the king of online behavioral tracking which also specializes in targeted advertising.

According to Wikipedia, Android OS is actually open-source but in ‘most’ devices it comes with proprietary components embedded with it. What does that mean? Is it really open source?

The answer is a big ‘NO’!

Well, I was also wondering the same and was looking for free & open-source alternatives to the conventional Android operating system, the apps, and services, etc.

Table of Contents

Free and Open Source Operating System

To obtain primary freedom from all things Google, we can make use of custom ROMs like LineageOS, AOKP, Resurrection Remix OS, etc. These operating systems are licensed under free and open-source licenses and are based on Android, that is – they are developed as free and open-source software but are based on the official Android versions released by Google.

Now, here are some free open source apps for Android –

Free and Open Source Search Application

First of all, the default Google Search app can be replaced with DuckDuckGo. DuckDuckGo claims itself as the search engine that doesn’t track you, unlike Google which uses filter bubbles for personalized search results. Moreover, some of DDG’s source code is free software hosted at GitHub under the Apache 2.0 License, but the core is proprietary.

Free and Open Source Calendar Application

Utilities like Google Calendar can be replaced with Etar.

Etar is a material design calendar based on the AOSP (Android Open Source Project) calendar.

Free and Open Source Calculator Application

The best open source calculator app available out there is the Calculator N+ Math Solver app.

Free and Open Source Weather Application

Good Weather for Android provides detailed weather in more than 200.000 cities and any geo-locations.

Free and Open Source Camera Application

Open Camera is a fully-featured and completely free Camera app for Android phones and tablets.

Free and Open Source Home Launcher Applications

Google Now launcher or any other proprietary stock launcher can be replaced with Rootless Pixel Launcher (highly recommended), Lawnchair Launcher, Turbo Launcher, or Open Launcher.

These launchers are freely available for anyone to use. They also allow you to personalize dozens of different elements on any android device so that you can have a home screen designed in your own unique style.

Free and Open Source Habit Tracker Application

Loop habit tracker application helps you to create and maintain good habits, allowing you to achieve your long-term goals. Detailed graphs and statistics show you how your habits have improved over time. This app is completely ad-free and open source.

Free and Open Source Web Browsers

We can replace Google Chrome with either Firefox Focus or Brave Web Browser.

Firefox is a free and open-source browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation.

Free and Open Source E-Mail Services & Application

Also, we can switch from Gmail to ProtonMail so that we can get rid of Gmail completely.

According to their official website, ProtonMail is the world’s largest secure email service, developed by CERN and MIT scientists. Also, they released the source code for the web interface under an open-source license. It’s quite easy to shift from Gmail to ProtonMail and forward all the new messages from the Gmail ID to the new ProtonMail ID. Check out this for step-by-step instructions on how to migrate completely to ProtonMail.
Moreover, they guarantee privacy, end-to-end encryption, anonymous email, and what more – it’s 100% free!

Free and Open Source SMS Application

QKSMS brings a refreshingly beautiful and responsive material design touch to the stale state of text messaging. In a world with clunky SMS and MMS apps cluttered with bloat and ads, QKSMS is something to get excited about.

Free and Open Source Video Streaming Application

Next, we can replace YouTube with NewPipe.

NewPipe is a free and open-source YouTube client that doesn’t use any libraries that are dependent on Google’s framework or any YouTube API. It also lets you download YouTube videos with total privacy. The best part is that it lets you stream music in the background and do practically anything you can do with the official YT client.

Free and Open Source Note Taking Application

Google Keep can be replaced with Orgzly | Notes & To-Do Lists

Currently, Orgzly is not an open-source project. Since the majority of its users are Org-mode users or users of other free software, it is the most commonly asked question. But in case it becomes free, the codes can be expected in GitHub repositories.

Free and Open Source Maps Application

Chuck out Google Maps and replace it with OsmAnd Maps (OpenStreetMap Automated Navigation Directions)

It is a free and open-source, global mobile map viewing and navigation app for offline and online maps for Android and iOS. It uses the OpenStreetMap (OSM) map database for its primary displays. The development of this project is being done on GitHub and the Android version is available under the GPLv3 license.

Free and Open Source Instant Messenger Applications

WhatsApp can be replaced with Signal Private Messenger or Wire Private Messenger.

Remember, WhatsApp was bought out by Facebook for a whopping $22 Billion in 2014. Why spend so much for just an instant messaging app with no Ads? Give it a thought and if you could come up with a proper answer, please do mention it in the comments section of this post!

Signal Private Messenger is a free and open-source application for phones, that employs end end-to-end encryption and allows users to send end-to-end encrypted groups, text, pictures, and video messages and have encrypted phone conversations between Signal users on iPhone and Android.

We can try to migrate from Facebook to diaspora* – a privacy-aware, distributed, open-source social network.

It is a non-profit, user-owned social network that is based on the free Diaspora software. It consists of a group of independently owned nodes (called pods) that interoperate to form the network. It is not owned by any single person or entity, keeping it from being subject to corporate take-overs or advertising.

This lightweight Pedometer app uses the hardware step-sensor for minimal battery consumption. This app is designed to be running all the time without having any impact on your battery life. It uses the hardware step detection sensor of devices like the Nexus 5, which is already running even when not using any pedometer app. Therefore the app does not consume any additional battery juice. Unlike other pedometer apps, this app does not track your movement or your location so it doesn’t need to turn on your GPS sensor.

  1. Thanks but it would have been more helpful if you’d said why you were recommending this or that item. Have you used them? What’s good about them, what isn’t, etc. Btw Open Launcher is no longer actively maintained and has been moved to github, might want to update. Thx
