All You Need in a Fitness Timer app

I’ve been using this app for a few months now. It’s everything I could imagine needing in a fitness timer app. It is so versatile and so easy to customize. I’ve saved about a dozen of my own routines and it only takes a moment to program a workout found in a magazine or online. And once it is programmed, it’s there forever, whenever you need it. And with the sync feature, you can have it on all devices. I’ve even shared them with friends who have the app using the export feature.

Save your routines to a folder... or two... multiple versions even... It’s up to you. I make full workouts for my normal routine and abbreviated versions for when I’m pressed for time.

With all of my routines on hand at any given time, I have one less excuse for just getting one done. In fact, having this app has made me MUCH more consistent in my exercise regimen. I can’t say enough about it. Seven Stars! *******

Ok timer that’s now bad

This was an ok timer. I was able to set up various workout routines. But in past 6 months, there’s been multiple issues. Some are minor but critical issues are: 1. Some intervals will randomly pause with 3 seconds left. Then about 5 seconds later, it would speed through the countdown 3-2-1-go within half a second. I know it’s not my device because it happened on multiple devices and the music still plasy without pausing. 2. In past three months, if I have the music on then launch this app, the music volume would go down. Most of the time, during the first interval, the music would go back to the volume I had set before launching the app. But sometimes the music would stay low. If I’m using the app for a run outdoor, i would have to force close the app and music, then try again few times until I can hear the music. 3. Sometimes you can’t hear the countdown to an interval. So I’m having to keep an eye on the timer. I tried changing my settings, try on my iPhone vs iPad, etc but doesn’t fix it. Really frustrating if I am out for a run, again having to force close the app and music, then try again few times until I can hear anything. It was worth the $ I paid back then, but I would be very unhappy having to pay for this now.

Compound timers frustrating to set up

I am frustrated and mystified with this app. The whole reason I bought this thing is so that I can do intervals while I'm running without having to pull my phone out of my pouch. Getting this to work for more than two types of exercise is ridiculously complicated. Navigation is not intuitive. There are nested timers within nested timers and it is unclear how they work. I have spent over an hour trying to get it to give me different beeps for different exercises (crazy, I know). I want a unique beep for high intensity, medium intensity, and low intensity. The first time I tried it, it gave me the designated beep at the END of the interval. Not helpful. Then I rearranged everything to have the beep at the end of the interval before. Worked in one instance of the interval, but then the beeps just stopped working after that, so I ended up just holding my phone while I ran so I made sure I didn't miss the next interval. AND the worst is, when you are trying to test if the beeps will work in a workout you set up, you have to jump to the interval before and just WAIT for that interval to be done. So if I want to test the beep for my sprint interval, I play at the interval before. If it's two mintues, then I have to wait for it to go through its two minute thing to test which beep is going to play. Terrible, awful, frustrating.
