This app is really great for multiple reasons

I’ve been using Seconds Pro now for 4+ years. I purchase workout routines from various trainers (typically in 8-12 week segments), and I program them into the app utilizing custom timers. Over the years, I’ve fine tuned the style and look to suit my needs, and this app has accommodated everything I’ve wanted to do when creating these timers.

I’ve also recently purchased an Apple Watch, and I use the Seconds Pro app on there during my actual workouts…it is incredibly helpful to have the intervals on my wrist while listening to the countdowns and up next announcements in my AirPod Pros…purchasing 8-12 week segments and having them programmed into this app keeps me on track and accountable to myself during the workouts as well as keeping me on track to each week’s programming allowing me to finish and keep progressing; this has been a critical part of my consistent training over time. (Hint: this is the key to fitness folks)

I’m writing this review as a genuine thank you to the developers of this app…this has been and continues to be the perfect tool for me. Thank you!

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! *******

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.
