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 4MB), so Just Run will take up very little space on your device
➕ Upgrade to Premium to get more trainer voices, multiple theme options, 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!

I used to use another app and after a time, it was changed and the developer put anything past the third week behind a paywall. I went looking for something else and tried others before finding this one. Just Run is simple and the fact the entire workout is free is incredible. I've been so happy that I decided to get the premium version just to support them. There are two things I would suggest for future updates: 1- a distance tracker, and 2- a run counter (you're on run 3 of 6, etc..)

100/5 stars. I was terrified when I found out I had to finish three sub 35-minute 5ks for my black belt test (which is hilarious in retrospect) until I downloaded this app. Before I started, I couldn't run for more than 30 seconds without a break. Now, I can run for 30 minutes at a consistent speed. The app is easy to understand and free of charge (although I recommend supporting the creator), not to mention I would still be stuck worrying if I didn't download it. I can't recommend enough!

Remember the days when apps were simple and didn't require a subscription. When they didn't give you a few free runs and then force you to pay. This app is that. No fancy coach or GPS connection. Full functionality for free and a couple cool features if you want to pay the low one time premium fee. I pay it just to donate to this awesome developer.

What's new

This update is based on all your feedback, thanks so much for your emails!

* Landscape Mode
I've heard from some of you that you use Just Run on a treadmill, and that it would be much easier to be able to place your phone on its side. Now you can!

* Improved Design
I've tidied up Just Run's design to make it easier to navigate. I've also chosen a more modern font which is much clearer to read. I hope this will help improve the app for people who emailed about readability issues.
