This is a pretty cool timer app and it's a good workout timer for crossfit and other workouts like calisthenics. It offers many options and there are even settings for other types of exercise, like running or calisthenics. 

If you are a regular gym-goer, you can also choose to get notified of your work intervals and have a reminder when you need to rest. If you are an interval runner, you can use the timer to keep track of your intervals and keep you on track of your progress.

All these options make the app more useful than just a timer for your workouts. There are many more functions in the app, but they are useful for any type of fitness.

With the timer you will know the time of every interval and you can pause the workout at any time. The app will work in the background and will notify you of new intervals or it can simply remind you when to rest. The app also has a cool interface. You can set the exercise mode as well.

You can pause the stopwatch at any time and resume your workout if you need to take a rest.

You can also add a custom interval to your workout. You can create the intervals for you and name them as you like, it will work as an EMOM or E3MOM for example.

You can also create your own sequences and choose your intervals and rest time.
