I turned off the default music during runs in the app’s music settings. However, whenever a coaching message plays or the app moves to the next section, the music automatically starts playing again. I had to keep turning it off manually during my run, which was very stressful. Until this issue is fixed, it will be difficult for me to continue using the app.

The problem is the language. I set to English and continue to show in Korean.

Hello. We will promptly improve and apply the fix regarding the issue where some text is displayed in Korean when changing the language. Thank you.

I found this app from a kdrama called Run On (the product placement was top notch) and it's motivated me to run week after week. I might even be addicted now, eventhough I didn't like running at all before. It's free and the ads are barely noticeable. You have the freedom to repeat courses, so I can progress at my own pace. I also put the speaker in Korean to help me improve in the language, and he's words are so motivational. Definitely recommend. I've even gotten my siblings to run with me.
