Weak Free Sample
The purchased version probably rocks. You can customize timers for all types of workouts and the standards are already templated to build off of. I tried the free version I the last 20 mins though and am aggravated that there are no saved generic timers. I fat fingered off the running exercise and couldnt jump right back in. Even a free version should have something generic to offer, right? Gonna shop around a bit. If this is the standard and I have to buy I would come back to this one.
