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

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 love this app! I've hated running my entire life, I've been walking for years but decided it was time to step it up and complete a 5k. I wanted a simple app that would play in the background and tell me when to walk/run over my music/show, and that's exactly what this app does. Simple and easy to use and the training intervals slowly increase at a reasonable pace. I would recommend being at a point you can walk a 5k before running tho, jmo. Thank you for the great app!

When I started this I had such bad endurance that moderate running for 2 minutes to catch a bus could leave me completely wiped out for a long time afterward. And I had to stop partway through the first run on this app. But I consistently stuck with its program and am now kind of in disbelief about how I can run for 30 minutes straight now. I didn't know it was possible to improve this much in only 9 weeks. This app made it all clear and structured for me and told me what to do at every step.

Whatโ€™s new

This update adds two new trainer voices to choose from, plus the app's first translation!

Aiko joins Just Run as the first Japanese-speaking trainer, to coincide with the new Japanese translation of the app. She is energetic and encouraging, and worth choosing even if you don't speak Japanese!

Jess is an upbeat and friendly Australian trainer joining Just Run. With Charlotte leaving the app at the end of August, Jess is a great new choice if you want an Australian accent.
