That program is now tied to the quick access program button on the main page.

You can tailor every program to meet your personal needs.

Judo Round Timer Pro is great

I was looking for a round timer and I came across this awesome timer. I’m a beginner Judoka but I love the judo theme of this app. The Kodokan symbol is really slick. I enjoy the ability to customize every aspect of my program and save it for later. I’m using this timer when I’m training Judo or just circuit training at the gym. Give this round timer a shot. You won’t regret it.

Judo timer? Yes please!

Just buy it. Judo Round Timer Pro is the best Judo timer out there. I didn’t even know about this app until I saw it in the store.

Everyone needs a round timer. If you’re a Judoka, you need this one.

Cool App!

I like being able to divide my workout into rounds and rest periods! Being able to configure multiple presets is great too! Thank you!
