There are plenty of workout and fitness apps on Android, including AI-based training apps, but most of them have one major drawback.
These apps are either paid or offer only a limited experience for free users.
Thankfully, just like with open source productivity apps, there are also plenty of open source workout and health-tracking apps for Android.
I’ve been using a few on my phone over the past few weeks, and here are some of the best I’ve tried.

Feeel: Keeps home workouts simple and private
Train at home without compromising your data
If you, like me, have a desk job that keeps you sitting for hours and are unable to work out regularly, this app is for you.
It’s called Feeel (yes, with an extra “e”), and it’s one of the best open source apps I’ve used for at-home exercises.
This app comes with a pre-defined “scientific 7-minute workout” with basic but important exercises for those who can’t make time for long daily workouts.
The app also explains how to perform these exercises clearly and intuitively.
You can create your own workouts or import ones made by others. Feeel supports both dark and light themes and offers daily reminders to keep you on track.
Best of all, the app is completely private, with no data sharing with the app owner, and the app also doesn’t have any tracking or ads.

LiftLog: Makes gym progress tracking effortless
Log sets and reps in seconds
On the other hand, if you regularly go to the gym and want an app to quickly log workouts, LiftLog is worth trying.
Unlike other workout trackers that require too many details — often slowing you down — LiftLog uses a simple tap-based system for tracking sets and reps.
The app comes with a workout library you can select from and tap quickly to log exercises. When you’re done, there’s a built-in rest timer. You can also view your stats over time to track progress.
The app offers a beautiful UI, plus options to share workouts with others and even compete.
LiftLog is free to use for tracking workouts, but if you want to plan sessions with AI, features like the AI Planner and AI Session Creator are available behind a paywall.

wger: Covers workouts, nutrition, and weight goals
wger is one of the most complete, powerhouse fitness tracking apps available. It not only lets you log workouts, but also tracks your nutrition side by side.
You can create different nutrition plans, log daily calories, and even use the built-in barcode scanner to instantly fetch and input macronutrients before eating.
The main homepage shows your vitals upfront, including workout sessions, nutrition plans, and weight trends over time. You can also quickly check calorie intake for a specific day at the bottom of the page.
The app is community-driven, so you can not only log your workouts but also create servers within the app to share with others.
For example, you can create a server and share it with everyone in your gym, and compete together.
wger is completely open source with no ads or tracking.

MediLog: Puts your health data privacy first
Track your vitals without sharing info online
Fitness isn’t just about working out. It’s also about tracking your vitals. For that, MediLog is one of the best apps available.
It offers a simple interface for logging various vitals, including blood sugar, weight, blood pressure, and cholesterol.
The app doesn’t offer the ability to track these vitals. Instead, it’s a straightforward tool for manually adding readings from your own medical devices.
It’s a great way to store and review progress over time and is especially useful for diabetic patients.
MediLog also includes a diary for notes, a document folder for medication plans, and a calendar view to visualize your data.
All information is stored locally on your device, though the app does include some ads. Nonetheless, it’s a secure, no-frills tool for keeping a personal health log.

Flexify: Minimalist workout logging champ
Fast, clean, and focused on what matters most
If you want a simple, minimal workout app, consider trying Flexify. It offers a clean interface focused on quick workout logging, whether that’s weightlifting, strength training, or cardio.
It also comes with a large library of exercises you can import, so you don’t have to add them manually.
The app also includes a built-in timer for tracking rest or assisting with cardio and abs workouts.
One key area that differentiates Flexify from other workout apps is its free plans section. In here, you can create workout plans for different days or select one of the pre-made ones.
Flexify is completely free to use, has no ads, and offers a highly customizable UI.
Forget the big names, these open source health apps are worth a look
There are plenty of popular workout apps, like Strava and Nike Training Club, but these can feel cluttered and often slow down workout tracking instead of facilitating it.
These open source apps not only offer a simple UI so you can track your workouts fast, but also keep a record of your body vitals.
