MJ101916,
Works great for HIIT runs
Best app I have found so far. It’s free and has a lot of settings. I only have 1 high/low intensity timer programmed in, so I dont know how many you can have without upgrading. But I only needed 1.
Baseballcurt35,
Loved but last iOS messed it up
This was an excellent app, however the last iOS update messed it up. Now when I start my workout (activate apple’s workout app) then start my Cero app, like I always did, the Apple workout app overrides the Cero app and Cero stops counting down (happens after the watch goes into sleep mode). The only way I can get it to work is to restart everything, turn off the watch, then turn it back on.
Before the last update this was a 5 star app for sure!

SpideyMike,
Perfect app for my HIT workout.
This app is great - the timers are easy to set and it works perfectly for my routines. Easy to change and add more workout timers - can even name them (squat thrusts or whatever). If you like high intensity workouts you must get this app!!
EmoEric87,
Love it
I love this app. I 100% recommend but not if they start charging a subscription or any of that ridiculous. Exactly what you need to hiit, or any kind of intervals at all.
Bobthetheman,
The High Quality Timer I needed
Man, this is such a well made app. Intuitive, simple when it’s needs to be, complex (but not complicated) when needed as well.
I was so surprised at the quality and attention to detail, that I just had to pop in to leave a review.
I work on a QA team and I know qualify when I see it.
Keep up the great work! You have the best interval timing app in the App Store!

disappointed #48,
Simple interface but poor functionality
Intervals are easy to set up but the signal at the end of the intervals are too weak or do not work at all. On my watch, the haptic feedback was too weak to be felt. I could not figure out how to make the chime work. On my phone, the beep was also too weak to be heard and the vibrate function did not work. I uninstalled this app. The search for a simple interval timer continues.
Not happy user 12345,
App mysteriously runs in background draining battery
I used the app for 2-3 times in the past 10 days but Battery shows the app used 24% of battery and has run a total of 15+ hours in background. Very alarming. But other than that the app suits me need for a basic interval timer.
Karina_Soto,
Great app!
Cero keeps me on track toward my fitness goals. Download it. Use it. See the change.
BgmKskn,
Needs more features
The best design I’ve seen so far but there needs to be warmup and cooldown features to add to workout as well. Also, trying to adjust time by only using the plus and minus signs is irritating. We shpuld be able to type the numbers.
CassVia,
Great App
Awesome app for intervals! Would give it 5 stars if you could listen to your music while using the app....please make that available and update the app 😁
