Interval Clock

Nice design, tone could be louder.

I look forward to changing my review but right now the app is crashing.

Can't customize sounds, no warm up or cool down intervals. Animation is unnecessary. UI doesn't adhere to style guidelines. However, it does work for basic intervals, and doesn't require unnecessary permissions.

I ride a sationary bike and needed an interval timer, this worked out well for me.

Nice design, tone could be louder.

this is exactly what I need. almost perfect. but app constantly permanently freezes and the only way to make it work is to reinstall

Wish it were louder!

This interval timer fails at keeping track of time accurately. After every interval it goes off by a little where eventually your intervals will be all off. I use the default 12/8 intervals which you would think add up to 20 seconds but on this app the total interval gradually shifts such that it isn't ending on a 20 second interval any longer. Went back to A HIIT Interval Timer.

Fixed the app for kit Kat. Back to be being the best internal app in the store

Love it I just wish it was louder.

Nice design, tone could be louder.

Crashes every time I open in on HTC One M8

On my LG Optimum 2X, app immediately closes right when the colour changes. Would be sweet if this could be fixed. I'd love to try this out. Keep up the good work!

Crashes on opening on Nexus 7 2013, 4.4. I miss using this app so much.

Does not appear to be working on KitKat 4.4.2, still it did exactly what it was supposed to do when it worked.

I use this when on my wife's cross trainer. Keeps me focused, breaks the monotony and provides a pretty good workout.

This app made me dust off the old stationary bike. :-) a feature I would suggest is an instruction section to clarify the meaning of the different colours for the first time user. That and reducing the app size.

It was working fine on my s3 but now the audio notifications force all sound through the speaker, not the headphones, making it impossible to use at the gym. Please fix!

Sounds do not work, and I did not see a volume adjustment. Yes, I tried adjusting the system volume.

Good, but a few points: It is quite a large app for its purpose in terms of memory. And it should have a portrait mode instead of defaulting to landscape.

Does just what I need. No more no less.

Can't open on Nexus 5. It crashes right away when opened

The only suggestions I would make are: Add a warm-up period at the beginning, and make the alarm louder.

I don't know if this is due to my current ROM, but the app closes immediately after switching color after the 12 seconds. When I restart the app, I't back to the initial start screen at 20:00.

Can't fault it, let's see if the science behind it holds up

Pros It works, it's simple to use, and it gets the job done. Cons Large app size Limited functionality

Been using this for a few sessions now works great especially for low vision users. Love it

Worked well on my old desire though..

Kicks your butt!

Does one thing and does it great.

On t mobile, on my s5, this app crashes when trying to open every time. Bummer.

Still doesn't work on my Nexus 5 :(

Nothing crazy! Add a status bar icon that's just a colored square so I don't have to stay in the app. And if you can add color notification light support, even better, then I don't need to have the screen on killing my battery.

First, it could use a face lift. Second, you could add background images or animations. Such as, a image of a person walking for the slow down, and a racing bicyclist for the fast pace. You can maybe have these images move also slowly, or quickly across the screen as well. Or you can add a heart pulse animation, one going slow, the other moving fast. Also it would be kind of cool if you can tie this to some heart monitor to see your actual heart pulse. Seek a app developer if you can,t make it happen.

This app has the best alarm sounds that I've found for an interval app. It would be nice for a portrait option, especially when trying to manage podcasts. My biggest issue is that, without a persistent notification, the app frequently closes if I switch to a podcast app, even for a moment. Adding a notification would make this app much more useful.

The functionality is simple, and all it needs to be. The execution needs help from a user-friendliness standpoint: As has been said repeatedly, the colors don't work, particularly for colorblind users. Use more complimentary colors (Maybe just the blue and the yellow for slow and fast). The buttons are small when they don't need to be. When the only functionality is start/stop/reset, I should be able to hit any of those with my eyes closed. Again, as previously mentioned, find a less "cute" font. Keep it simple. There's no notice that the app runs in the background, and no way to access it without keeping a shortcut on the home screen. There should be an icon int he notifications area when the app is running that lets me get to it quickly while I'm using another app. (Less necessary): doesn't rotate to accomodate portrait view on my Droid RAZR. These fixes would make this a great little app.

- The clean interface is very nice. Colors are good too. I suggest blue for cooldown, instead of yellow. - The font is terrible, in my opinion. Maybe offer other font options? - The sounds are great, but I miss some kind of beeps 2 or 3 seconds before the beginning of the next cycle, just to get the user prepared. For now I'm using "A HIIT Interval", but I'll switch to this one if at least the beeps are implemented, because this app sounds and looks much better.

For an app that's a simple app and designed for losing weight its ironic that it's 10x larger then it needs to be. 9mb for a countdown timer that changes background colors?

For the colorblind crowd (E.G. me), the colors are a bit too close. Unless I'm looking at the phone when the colors change, I can't tell which mode I'm supposed to be in. Blue/Green might be a better choice; a color picker even better. 9MB? That seems like a bit much for the functionality it provides. Permissions for Full Network Access? For a countdown timer? .... why? I didn't see any ads...

You can also combine it with other workouts and it'll get you fit in no time. It was nice to use the old bike in the garage
