"This is exactly what I needed. Something simple with a huge button that you can't miss. I need to time stuff without looking at where I'm hitting precisely on the phone." ***** -App User

Imagine being able to tap anywhere on the screen to start and stop the stopwatch! It's all about big buttons. REALLY. BIG. BUTTONS. Impossible to miss buttons. The ENTIRE display is the button.

Start Stop was the app discussed on the Vinnie Tortorich Podcast Angriest Trainer, Episode #280! Check out the podcast at or iTunes!

Great for when you need to keep your eyes on the action, not on your phone!

Check out a short youtube video to see the app in action! Go to and search for "start stop stopwatch"

"I work in animation so I need to use a timer often. The default timer on the iPhone I found isnt too good because I would miss hitting the buttons. This app is perfect because the buttons are huge and you cant miss." ***** -App User

"It is easy to use and suites my needs for a new exercise program I started. I tried a couple of free timers, but one was difficult to reset and one kept showing adds. I would recommend this app." ***** -App User

"The timer that comes with the iPhone has a small button that you miss if you are watching a race. This one works. Thanks." ***** -App User

You’ll never miss hitting START or STOP with this app. Great for children, the elderly and everyone in between. Combined with unique sounds for each function you can even use this timer with your eyes closed!

Great for timing sprints


(Developer: could you please look into why the app no longer works in the background? I am using an iPod Touch 5G with the latest software and I used to be able to start the stopwatch, open up other apps, then check the stopwatch which would still be running. Now when I check it, it is always reset to start. Thanks for the help!)

With other stopwatch apps, I would struggle to find the tiny STOP button when I was nearing the end of a sprint. This app features a FULL screen stop button so all I have to do is hit anywhere on the screen to stop the timer. Fantastic!

Best in Class


I've bought maybe 12 timer apps and for me this is best by far. I mainly use it for timing LeCoultre Atmos Clocks which the minute hand jumps once exactly every 30 seconds. Any deviation over 15 or 30 minutes tells me how much to move the timing regulator lever.
Most timers require you to hit a tiny button to start or stop and half the time I miss and curse and swear and try again the other great thing is timing is to 0.01 seconds. Most timers only measure to 0.1and after 60 minutes you lose the tenths altogether. I don't need to time laps or any other complications. This app does exactly what I need and does it very well.

Very Disappointed


I love the simplicity of the design, but the timer is junk. When you hit "start" the time on the clock varies anywhere from .00 to .99. I ran a number of comparisons with 2 other apps and the times varied up to a second off. (When comparing the other apps among themselves the time only varied by .02 seconds.) This app is way too unreliable for serious use. Hopefully an update can fix this problem.
