It’s great.

Real great.

Not Free

You can only use your created timers ONCE. Then it’s a paywall.

Seconds interval timer

Absolutely brilliant timer. Have used it for years, and will continue to do so!

Love the app

It is soooo easy to customize your timers, and love the fact that if I do a circuit timer, that it says the name of the exercise each time. That way I am not looking to what comes next. Amazing!

You can create any workout you need

Because you have the ability to create any workout you want, you have no excuse not to workout out. I’ve used it for years from circuits to intervals.
