HIIT interval training timer

The app seemed like it would be simple to use (it is) but I cannot figure out how to do sets. I can do all the reps I need, but I would like to group them. Am I missing something? Also, the survey link is not functioning, so I have to leave my input here. I kinda want my money back.

Used to work perfectly, but now the buzzer volume is extremely low. And yes, I've turned the volume all the way up. All it does is turn the media (music, audio book, etc) I'm listening to all the way up, without effecting the volume of the buzzer. If this is fixed, it's absolutely a 5 star app. Used it for years, but this problem is a big one.

Only held back the extra star for one feature I feel is missing which is to have "splits" inside the work period. E.g. If my outline routine is 2 mins work, 1 min rest, I'd like to be able to split my work into 4 units of 30 seconds with signals to move onto the next activity. Hope that makes sense. Great job so far. Thank you!

This does what it says and is reasonably flexible. You can change the workout times: prep, workout, rest, #repeats, and cool down. Before I got this app, I was just using stopwatch app but this got tedious for different intervals. They even offered a survey. The only ding I give is that it should offer a landscape view. I paid to remove ads. Worth the $1.50.

Bought this app and then got a new phone. Unfortunately this app doesn't work for my new phone. Resolution is all messed up. I contacted developer but never heard back. shame on you!

App was working great but lately it will stop halfway through a workout and I don't know how many mins I have done. This is frustrating!

Tons of bugs in this. It has all the right features but really, you had one job. Crashes a lot. Loads the wrong saved workout. Useless

So easy to use and very user friendly. Been using it for over a year. The one grif I have is that if you have it paused already, then go to make a phone call, when you end that call, the app automatically resumes

Great app! I use it for all my workouts. However, after a few weeks the sound stops working and I have to uninstall then reinstall and re-program all my workouts. Otherwise great app!

I use this app almost daily for my HIIT cardio. The design is great and user friendly with minimal time to set up and get working out. However, about every other day, halfway through my workout, the app will reset itself and stop timing me. I'll be in the middle of a high intensity sprint and wait for the timer to tell me to rest and just wait and wait and wait. I would give this app 5 stars if that could be fixed.

I have used it almost daily for several years and it is a great app. The only thing i wish would be resolved is it shutting off when i have an alternate screen pulled up during a routine; it just turns off about half way through the workout. I get around it by keeping the interval timer up when i workout but sometimes it is nice to quickly reference a move. That's the only item i wish would be resolved, otherwise it is great.

Not useful anymore. I simply want to do 3 sets of 30sec without a rest in between followed by a 45 sec rest. It used to be possible but now I don't seem to find the option. I think this is a basic kind of flexibility that an app like that should have. If there is such an option - why would you make it so difficult to find. Either way I will have to find a new app.

The Good: basic, reliable, gets the jog done. Not so Good: During training, I swear it missed intervals sometimes. I just finished a half marathon and confirmed that once I never heard the interval start and on another it never ended. But that's just two errors in less than 2 hours and if you run a lot, it's easy to compensate. This is not a bad app.

Sounds cues per interval work well and the storage is smart. But the command keys only show as a black tile. Also, other interval timers have the ability to change interval length per set of intervals instead of a fixed duration for all intervals. Also, switching apps causes it to stop running the timer.

Agree with Eddie and his review. I've used it about 10 times, and I'd say half of those times, the app stops, when I put the screen to home, and eventually it goes to black. Can that be fixed, or does the app always have to be showing on the screen. 40-45 minutes is a long time to have the screen awake. Other than that, its really good, and I like the customization. The warnings could use more options.

I actually love this app, and paid for it. However, I listen to Google music when I run and the volume of HIIT Timer is so low I can't hear it under the music. Please fix this and I will give you 5 stars! Also, it som we times resets itself in the middle of my run, and I find myself waiting and waiting for my rest interval.

Very simple, clean app thats been huge in my physical therapy as I'm gradually working to running again. I'm not trying to figure out when i need to start walking or running, the countdown gives me motivation, and i don't lose track of how many sets of walking/running I've done. Pause button is easily available if i need to take a second to stretch out. I haven't yet had any issues with bugs or the program closing mid workout, which I'm thankful for.

Love this app. Paid for the ad free version. Never had any problems until I got a new phone. I originally had the galaxy s5, now I have the galaxy s7. The 3 second countdown timer does not work anymore. I check the options and it says it's "on" but does not sound. How can I get this function to work again? I'm a personal trainer and I use this app daily. I need that 3 second timer back. Thank you.

I would rate this app 5 stars if they fixed the memory leak issue that causes the program to stop mid workout. I saw responses from the Dev saying it is because the phone runs out of memory, but if the app wasn't consuming so much it wouldn't be an issue. I monitored memory consumption and found the app spikes after 6 intervals. Please fix because this can be the perfect app for interval training!

Brilliant lil app.. works alongside my music and doesn't over ride the songs.. gives me a 3 second count down before moving to rest/Sprint.. will be using a lot. 5 stars. Thank you x

It's nice that you can create your own workout, but it would be better if you could add multiple time-different intervals. Also, it seems to close on its own right around my last intervals so I have to reset it, which gets annoying.

The other 3 HIIT timers I tried had a bunch of useless options and tiny controls, making them annoying to workout with. This has all you need and nothing else.

I am a trainer & its great for my Lift Like a Girl class when we are doing times workouts & the whistle is loud enough for the class to hear over the music. The ads are a little annoying but cant beat the functions for a free app! Highly recommend this app!

I find this app generally useful, but I often find that when my screen turns off, or when I change apps and come back to the timer, it resets itself. I wish that it would be able to run in the background instead of needing me to keep it on during my workout

After buying the app using in-app purchase (which remove ads only) the application doesn't get any updates. It also started to be unstable after a while. Kept sending emails with NO REPLY from the developer . There are better free alternatives for this.

2nd time I've had to reinstall, every time there's an update it loose sound no beeps nothing otherwise I would give 5

I was actually going to create an app like this but decided to see if one existed first. You should try to incorporate a way for it to work on a smart watch or fit bit.

I've been using this app on my Android phones for a few years with no complaints. Recently, the app started to have sound problems: when listening to music, the timer app becomes muted, impossible to hear. I've tried closing other apps, restarting the phone and playing with sound settings. I can't determine the source of the problem. I hope an update will fix it so I can change my rating back to five stars!

Suddenly, I can't hear the buzzer or voice function so I have to workout and watch it so I know when to rest and work. Ugh. Update: I tried all the fixes but had to reinstall. Now, the sound is getting weaker and weaker. I listen to music as well so it's a pain having to be uber conscious of the buzzer.

Had purchased and installed on previous Phones (Nexus 5, Nexus 6). Upgraded to Pixel and was asked to re-purchase it in order to remove the adds, and the cost was $2.00 instead of the $1.49 as advertised There is no way to contact the dev via the app nor the store and can't get my money back either. Leaves a bad taste in your mouth for what was an overall good app.

I understand the in-app ads in exchange for free. What I usually do is try the app then pay for it if I like it. This one, however is obnoxious. I really am not looking for a girlfriend in Korea.

Does exactly what you need for sprint training. One minor gripe: it would be nice if it would muffle other audio on queues. Can hardly hear it over spotify. Also, a queue with current iteration number would be nice.

The app was fine until I purchased ad-free version. After the purchase I could no longer modify workouts. I received no assistance from the creator of the app. You would think they would have been excited about helping an actual customer????

Works decent, but if you open more than a couple other apps while it's running (music, texting, Internet ect) then it will shut off and you won't know

I used it on my phone and love it, so i installed it on my tab S2 9.7 and the screen size is wrong and I can't see the go button to start the work out. Fix this pls!

Perfect app for intervals. Even gives you the ability to time warm up and cool down periods. Love that the screen doesn't time out while you're working out - that's always annoying.

I like this timer but sometimes during workouts it shuts down and I have to reset my intervals. Since I read during cardio, I can lose track of how many sets I've done. :(

I use this for running. It always seems to stop after 2 or 3 sets. Then I have to fumble with my phone to get to start again and it starts back at the warm-up. Very frustrating.

Love the app, works well. So well that I decided to support the developer, and myself, by buying the ad free add on. I hate having the second app on my app drawer. Is there a way I could get a code to redeem from in app so I wouldn't need the 2nd ad free app? That's the only thing from making this a 5 star review. Thanks.

I would love more customizable options. Like a 30 sec beep for when I do 1 min intervals but need 30 secs to change hands or feet.
