Very good, just one thing

This app is great to organize your workout the only issue that I have with it is that when you’re listening to music from another app the app automatically lowers the volume and you cannot get it to its full volume unless you close the app, it would be great if you could turn off that feature

Not a Critic, but I am a fan

I think this app is very helpful to those trying to get in shape. To be honest I love it, not because of the YouTuber who made it, because it helped get into shape. The only problem I have is that it doesn’t have a digital trainer telling and boosting my confidence, but it is very helpful.

Really dislike it. :-(

I loved the old version of the JY timer. I got a new phone and downloaded this version and didn’t like the interface and I missed the colored circle of the last timer. The font is too small and also visually unappealing. Also, this version eliminated the different sound alert choices from the last version. I love Jordan Yeoh, but will shop around for a more better HIIT app. Only thing that I do appreciate is the added muscle workout timer. Please bring back the previous version as an option
