About this app

Just Run is a simple workout app to help you get running. I made this app to get myself off the couch and start running to get to 5K. Stick to the workout plan, and you'll be able to run 5K in 9 weeks. It really does work!

If you're already able to run 5K, Just Run also has a 6-week plan to help you get up to 10K!

Workout Plans
- Zero to 5K: Gets you from absolute zero running experience to 5K in just 9 weeks, with three 30-minute workouts per week
- 5K to 10K: If you can already run 5K, or have finished Zero to 5K, this plan gets you to 10K in only 6 weeks

Features
📅 Target dates for each workout, calculated based on your progress, and optimal exercise days
📣 Choose from multiple trainer voices, which tell you exactly when to run and walk
📱 Lock screen notification so you don't need to unlock your phone to check your progress
🚫 No ads! Ads are no fun, so Just Run has no ads!
🎵 Works with music, audiobook and podcast apps - Just Run will briefly lower the volume of the other app when prompting you to run and walk, so you'll never miss a prompt
🔽 Tiny download (less than 5MB), so Just Run will take up very little space on your device
➕ Upgrade to Premium to get more trainer voices, multiple theme options, access to feature previews, and to support continued development of Just Run

I'd love to hear how you're getting on with Just Run. You can email me at run@jupli.com.

Just Run is the successor to Syncostyle's 5K Trainer and B210K Trainer. If you liked those, Just Run will feel very familiar!

It's a really simple app, and that's exactly what I'm looking for! If you want an app that tracks splits, has maps, has detailed breakdowns, etc. there are other apps that already do that. But if you want an app that helps you set a simple running plan, does it without bloated features, and does it without bugs, this is the app for you. I'm pretty cheap and rarely pay for apps, but I happily paid for this one.

I've tried several running apps, but this is my favorite. Here's why: it doesn't talk too much. I know some people like hearing motivational phrases to help them along, but I would usually just swear under my breath in response to the "coach" telling how much I had left or that I needed to pick up the pace, plus it always interrupted whatever I was listening to, which was annoying. With this it's just, "start running/start walking." This isn't high tech, it's basic AF, and that's why I love it.

I have been using the c25k app for many years but now they are charging a monthly subscription fee for the basic program. Absolutely not. I was looking for a no nonsense app for keeping track of my running intervals. Just Run is perfect for what I'm looking for. I even paid the one time suggested fee for premium for no other reason than I'm grateful for it being one time and for a simple solution.

What’s new

This update brings new a bunch of features and improvements!

- Added a new Feature Preview, Circular Progress Bar, which shows your workout progress as a circle in the middle of the screen
- Based on all your Feature Preview feedback, I have redesigned the Timer in Notification Bar to make the time much more visible
- I have rewritten the timer code to make it more reliable in the background, especially on Android 16

That's all for now. Happy running!
