Gets the job done. I like apps that do what they advertise seamlessly. This app is one of them, the user interface is simple and easy to use. It will alert you with a beep sound when it's time to work and when it's time to rest. The reason I gave it four stars and not five is because of two things that need fixing in my opinion. First, when you exit the app and come back to it the interval values go back to default, instead of keeping the last values you put on. Second, the last interval that is counted has no rest.

Simple and Elegant Interval timer. Perfect for weight training and Interval training. It can be operated from the lock screen from the pull down menu which is ideal especially when I'm tracking my weight lifting stats in a different app. I've tried out many timers and this beats them all. The only upgrade I would suggest to add multiple interval timer so that I don't have to reset them for each type of workout.

Very simple and useful. Works great for sure. Only thing I would ever add is an extra rest timer for after you've done all the workouts. That way I can do 45 sec workout, 15 sec rest 5 times and then 1 min rest before I repeat it again 2 more times. But even without that, this is the only interval timer I really use. Great app. Thanks for making it for us!

I love it. Great app. Thanks! A friend at work became my bicycle buddy. We ride and exchange health and weight loss tips. She's lost both pounds and inches and caused me to become a Newby to Kettlebell. On the theory that "what you're doing and thinking and talking about, you should be reading about," I downloaded the kindle book, "21 day Kettlebell Challenge" where I first read "interval timer" and downloaded this app. It brilliantly keeps this rookie on timed intervals. Simple, intuitive, without learning curve, sweating bullets.

A little too simple Just a little too simple, it requires the screen to be on in order to beep the intervals so unfortunately no good for the long distance running i want it for. If it would beep while the screen was off then very handy and 5*'s if you want it for sit ups and the like when phone life is not an issue then it would be perfect. Also it's refeshing to download an app that doesn't need to know everything about your phone and mine your info.

Simple but great Very stripped-down basic interval timer. Not quite as versatile as some others but really it's all you need for most things. The Simplicity makes it very easy to use and the colors that indicate which stage you're in are great when you're doing an active work out and don't have time to really stop and focus on your phone screen.

Liked it's simplicity. I have 4 exercises to do so that made 4 sets. The only thing is I then repeat those 4 exercises 4 or 5 times but there was nothing to make the app repeat them automatically. But I just reset and started again and kept count myself. Would have liked to name each set after the exercise, but that is a minor point. Easy to read the screen which was great.

My phone hangs dead while this app is working It has nice interface and is very simple to use. But it hangs my Moto G4 plus like anything. Once I start the timmer, the phone hangs to such an extent that even to unlock my phone, I have to wait for 1 min. If I pause the timmer, everything goes normal. Please update this app and make it more usable on phones like mine

Almost perfect. Would be 5 stars, if the beeps didn't stop music and instead had it still playing at a lower volume in the back ground, like it does on Google Maps Sat nav. (I'm on HTC One M9, don't know if this is a feature available on other phones, but I can't see a clear work around). Otherwise, great!!!

Not For Procrastinators This app is simple and straightforward. More time to workout than having to waste energy on setting up the timer and the start/stop buzzer unless you want to procrastinate. Select the number of sets, the work and rest intervals, hit the play button, and get busy. If you have a fitness band like FitBit or UP, it will track and save your workouts for you. This app consists of one page and that's all you need.

Does one thing and does it well Just what good software should be like. No bells, no whistles, no gigantic menu of configuration options, no attempt to meet all imaginable requirements, and no special permissions to approve. Why should an interval timer need access to my files and personal details? This one doesn't. Thumbs up!

Had high hopes but almost useless I had high hopes since it didn't ask for any unnecessary permissions, but no music while timer is running, no audible change between intervals, and no accessible settings. I guess this app could work for something like administering a test where you can leave it on the table. LG Volt.

Simple to use but... The problem with this app is that the screen has remain on in order for it to function properly. However, this kills the battery. When the phone is on standby, the timer does run in the background but the beep doesn't sound to let you know you've reached the end of the session. This for me is kind of a major problem. Thanks for all your efforts but please, can you help fix this and I'll happily give 5 stars.

Really easy to use. I set how many rounds, how long each session should last, and how much rest time between. Turned my volume up so I could hear it. It counted down from 5 to let me know to get ready, then it started. When it was done it let me know and congratulated me on finishing! Great app!

How is this rated so high there are no options set I don't understand why this is rated so highly. I don't need audible tones to tell me when to start and stop. I'd love to turn this off but there is zero options whatsoever. Nice minimalist design but it was the stars because it doesn't allow me to control What I Hear during a workout.

Love it Works perfectly. The beeps even sound when I have my headphones on listening to music. Also very easy to use. The only improvement would be the option to add a warm up and cool down to the total time, separate from the repetitions. Great work :) The only change I would make would be the ability to add different interval times instead of only being able to use the same time.

It works but has some features I don't like The timer doesn't make sound if the screen is off. Also, when I'm connected with Bluetooth headphones, the sound comes through both the headphones and the phone speakers, which is not ideal for public gym use. I wish I could change the volume for the alarm sounds.

Simple and does what it says. The different coloured screens and beep tones also help to differentiate exercise and rest periods without requiring you to focus on the screen. This is really useful eg for HIIT on a bike. Highly recommended for a functional, no frills app that just works without fuss or unnecessary options.

Good timer but too loud Works great. The only issue I have with it is that if you minimise the app, if you want to put on music or a video is something, the volume gets cranked up a LOT. Adjusting alarm volume doesn't do anything. Other than that it does what it should and is generally pretty nice.

The simple timer I've been dreaming of! It does exactly what I want it to do. I would pay for two upgrades 1. Being able to choose the timer sound and 2. The ability to save multiple timers for different activities. Even without those I seriously love this app. The ability to listen to music at the same time as using it is fantastic!

This app is great! I would add two features: the possibility to set irregular time intervals (1' work, 30'' rest, 2' work, etc.) and an option to save presets, since must of us use different patterns for different activities. I'd gladly pay for it!

Decent app with three mostly insignificant downsides Like other comments it is a great and simple to use app that is easy to start using. The three downsides are that it doesn't do a rest period after the last interval, it won't work unless the screen is active, and you can't really have altering workout and rest times during a cycle (you can't do like 30 seconds on to 1 minute off to 40 seconds on)

Great but... Awesome timer works really but 2 star because the sound somehow doesn't play just through hesdphones/Bluetooth speaker and also plays through the phone itself. I found this annoying as I like to listen music while I exercise. If you could implement a way so it just plays sound through one audio method I will rate 5 star. Thanks

Good for workouts. Keeps me focused and with no excuses. The sounds are not very nice or intuitive though. It's just a beep. It lacks positivity, like there should be a nice chime or something to indicate a good job with the interval. Just needs some more uplifting noises if that makes sense.

Works pretty well Had some issues with music app stopping after current song after starting the timer. I did find that if I started up the music app again it ran continuously after clicking play on it after the timer started. Otherwise it works great. No bs requirements for access to contacts or anything else.

The best interval timer. Simple and easy to use. Only problem though is if they could have it vibrate when it's switching between workout and rest. When I get into my workout too much I sometimes can't hear the beep and forget to rest or start the workout.

For a free app that has no ads or other kind of disruptions it's brilliant. It's for people that want a simple interval workout without too much BS. The color change between work out and rest is handy. Music stops when the alarm beeps would prefer it to go low but I use the quiet time to mentally prepare for next set! Used it twice and very happy with it will sure recommend it.

Eureka! After scavenging in the Apps store, I have found a App I am looking for. It is simple but cater my need perfectly. Many of apps I have installed, have very comlicated process which is not ideal for ur gym session. However, this simple looking app is working amazingly for me. Thanks for creating it.

Perfect for my needs I'm doing training with kettlebells. I do a 30-second exercise and then switch to a different position. On this app I call it a 30-second exercise with a 4 second interval. That gives me time to switch in between but it's like having a trainer making me go and not letting me rest too long. I set the reps to 58, and it takes care of the rest. Terrific

This is nice and simple, I really liked it, but it no longer makes sounds, so I have to keep an eye in it. It used to make sounds. I uninstalled, reinstalled, still no sounds, so I'll try a different interval timer. I emailed support, got a reply to make sure the volume on my device is turned up. That's not the reason the app sounds aren't working, so no help there.

This is exactly what I needed. You enter the amount of sets you want, work, and rest and it beeps upon finishing that set and rest period. It also starts counting down (beeping) at 3 and the background changes for rest and work. No frills or distracting nonsense. I am so happy I found it.

Simple but works well, and ad-free so far Has a very simple feature set that lets you programme number of laps, interval and rest period. Would be great if you could set different intervals within the same workout but hey it's free! Also plays nice with other audio, so you can listen to music and just have the interval change beeps play over it.

Does what it says. Three beep countdown at beginning of each work and rest interval so there's no need to check the countdown timer with different colours for each section you are on in case you forget and want to glance quickly to check. Missed out on the 5th star as there is no function to customise the timings. For what it does though - a great app!

Simple, no ads, & my own music! This is perfect for managing my timed circuit training/bootcamp and lets me use my own music. I put in the number of stations, how long I want to work, and how long to rest in between. Beeps to let me know when a rest is coming and when to get ready to work. No ads, nothing to configure, nothing to lose.

Addresses the need. It is a brilliant product that simply answers to the requirement that it is built for. A few changes would be great: 1. The interval sound could have more options for users to customize as per their requirement. 2. The interface is bit bland which gives it a college project feel. It would be great if it could be made a bit more lively. Overall it perfectly answers my requirement. A big thank you to the entire team!

Did exactly what I wanted Put in the number of reps, duration, and breaks. Worked out great for my workout and can listen to me music at the same time. I like that it had about 5 seconds to allow you to setup after hitting start and the beeping count down towards the end of a set.

Since most of my exercises are done using reps and sets, I don't use this as much as I could, but it definitely makes the time-based exercises I do much less of a headache! I particularly enjoyed the 5 second countdown whenever you start the timer!

Love that it is minimal, however the sound could use some tweaking. I don't need my ears blasted out when my headphones are in and it doesn't need to alert the whole gym when my headphones are in. The alarm is a horrible frequency and I can't find a way to adjust it. Aside from that, I would have given it 5 stars. Fix the alert and I will update the review.

Wonderful Set it go to work. Nothing to miscount or miscalculate. I worked out at midnight and I did not need bright lights to get through all the 8 sets on my recumbent bike. This gizmo walked me through all the acceleration and coasting.

Simple design. You insert how long you want to work, how long you want to rest, and how long you want to repeat it. It beeps for the count down at the three sec mark. You can switch that off if you like. And the timer, as you can see from the app pics, fills the whole screen and indicates which section you're in (work or rest) which are both nice features when you're popping around exercising. This timer is simple.. I tried at least five other timer apps and they were all far too silly. This one was EXACTLY what I was looking for.. and it doesn't take up much space on my phone as the others because it is so simple! Thank you!!! Please don't ever change!
