Interval Timer

Simple, no extra bells and whistles, and does what it needs to do. I've been looking for a simple interval timer for my yoga routine and love this. I simply set the times and I'm ready to go. The double bell to indicate go, and then the single bell to indicate rest, I thought was new and clever for me. The app works very smoothly, no glitches. UI is important for me and this had a nice one. One thing I'd like to see is the ability to change the bell sound or have a set of options to make it more fun.

The "Super Star APP" It makes us, Healthy Doubled our productivity. Gives us lot of free time. We highly recommended it to anyone. We work 20 mins continuously and 10 mins break. We do some exercise ( 10 push ups , 20 abdomens) We only do two five rounds and one three round. Then we are done for the day. We have doubled our work. Usually scheduled Day start at 7.00 am and ends 2.30 pm. Try it and it will change the way you work. Also a quick note we use standing desks. Thank You Guys!

About as useful as a tea cup without a handle. As soon as you press start you have to throw your phone or tablet down and start pumping immediately!!!

The program ends in the middle of the workout most of the time. When it does work for the entire workout I love the ease of use and simplicity.

I like that the bell plays in my headphones and not aloud, prefect for intervals in the gym. However, running the timer with the screen off results in inaccurate times. E.g., 30 seconds according to the timer is actually 45 seconds when compared to timex wrist watch or gym clock. Needs fixing.

Uninstalled because I couldn't chose my own alarm sound. The triple bell is annoying and obnoxious.

It doesnt work ok when sreen is off

When the screen is off the timer runs about 3 times slower. Pointless.

Ads take over my whole screen.

The app is perfect, simply what I have been looking for...only if it had sound. I constantly have to have it on view and this is destructive. With sound it will definitely deserve 5 stars from me. If there is any setting I don't know about which can help with sound, please let me know

Works nicely but takes ages to load if no data connection. Weird occasionally adverts. Battery drain is also high. Recently got Android Stability warnings advising me to uninstall! My phone is Note 4.

Can't seem to make it through a one hour run without it crashing at least once and eventually killing my battery

After trying for 20 app, this is the best app for me to keep. The app is simple and easy to use. It helps my daughter do minute math. She likes the sound. It motivates her. Thank you.

I've set it for interval training of 5 min and 1min rest. I finished 4 songs of total 20minutes and the 5 minute seem not to move more than 3mins. That and the annoying ad at start!!

I set it to an hour then start it, but when I come back to check it ten minutes later, it has reset.

Very slow to start. I'm assuming because of the ads. I'm giving up. It does not perform when I need it

Crashed twice in 30 minutes. This app has a major problem. Unreliable.

The counter wouldn't stop going even when app wasn't going was such a good app when it actually worked

Doesn't work if you lock the screen so sucks battery and I can't put in pocket when running intervals, fail.

Does interval timing but kills my battery

Cant change the sound. Same sound for start and stop. Can't change the countdown

Vibration would be better than a sound

No sound when starting and ending workout session

The app does evening I want it to and the ads don't really bother me. The major problem is noticed with it is for an hour of usage, my phone shows it uses 40% of my battery. I'm not sure if I'm the only one, but I usually don't have issues with lesser used apps.

Exactly what I was after but I'd prefer a selection of different tones/alarms instead of having to use the default boxing ring-type bell

Tried numerous times to install on the one+1 phone. Comes up with the very coooool "in" logo but then nothing. Uninstalled now :-(

Great simple app. Very functional. Annoying ads when opening the app. Would be happy to pay a small fee to remove them.

I do wish there was a pull down tray menu item for accessing it or watching it run outside of full screen mode. Other than that, it's perfect.

I wanted a simple interval timer with an alarm I could hear over the music I was streaming through my phone and this was it. No b.s., just a simple timer with work and rest sets. I like that you can set it to unlimited sets. That's really useful.

Requires an internet connection to open. Only lets you adjust the two states (work and rest). You cannot add more, or even delete one. Asks "are you sure" when you hit stop. This app is terrible and I deleted it after 2 days of use.

Great for HIIT. Simple to set times and number of rounds. It remembers my settings so it is ready to use each time. Would like to have ability to set sub-timer for switching activity during the work interval, but the big count display means I can work out the activity switches myself anyway.

Only one thing is needed, some adjustable number of seconds preceding first work i.e. time for preparation. 5 stars for all everything and hope that in some next release that possibility will exists. Yes, also some longer duration of last alarm when all rounds are finished. Maybe cute option will be for user be able to set first rest then work period. Including others audio files beside existing is technical matter. Great program. I use it mostly for rope jumping.

Ringing bell is a show stopper... User must be able to modify alarm sound.

Really like the simplicity, and the boxing ring bells are surprisingly motivating. But it's crashed on me on every run. Frustrating!

Should have vibration only mode too.

When the screen is off the timer runs about 3 times slower. Pointless.

Turn the screen of and the timer is very unreliable.

Doesn't work on a Nexus 5 running 5.1.1. The splash screen appears, but that's it.
