Easy to configure

This has worked well for me as a Masters Swim coach. My swimmers really liked it. I spent some time looking for a simple to set up and flexible interval timer with a strong visual element that made it easy to see how much time is left in the set. This fits the bill.

I strongly agree adding an Apple Watch companion app would be super helpful.

For traditional martial arts it’s one of the Best

So you like to do Chi gong or Nei gong stances or sitting postures. You may have 2 or more stances or postures you want to do in consecutive order. This app is for you. You can make a timer for setting up for your first posture the timer of the first posture in another time or after to give you time for the next posture for example (:20,3mins,:15,3mins)
20 seconds to set you up , 3 mins for the first posture then another 15 second timer to give you time to change into the next posture, then 3 mins for the second posture. This is just a example for extreme traditional martial arts enthusiast or professional athletes that wants to cut right to the chase while in airplane mode all business.

Best gym time I’ve found yet!

I love how it’s simple, yet customizable. I wish it was possible to build workout routines using a computer connection, because it’s sometimes hard typing everything in from my phone (I always wind up with so many typos) and trying to reorder things, but that’s my only “complaint” and it’s minor. Still love this app!
