Great stopwatch

Been using this for several years in my job as engineer. Great to be able to run many splits, type in notes about certain split times, then export all the results to a CSV for data crunching in Excel.

Great App

I installed the latest update and I must say this app is now perfect, the only thing I wished it could do (run in the background) it can now do. Thank you Pencil Busters! One cool feature you might consider is a strobe light that you can activate when running at night, I have been almost run over more times than I care to remember, if you included a blinking red light or flashing white flash light feature I'd be totally psyched! Great app, definitely worth the $0.99!

Would have been a 5 star rating, but....

This app is great for getting my split times during my Crossfit workouts, but I wish an upgrade is made for the "Lap" button. Whenever I want press the "Lap" button: the phone beeps, the "Lap" button blinks once, and the "small" stopwatch at the top right side, resets.
PROBLEM: In a loud gym, the beep cannot be heard, also my finger covers the small "Lap" button, so I cannot see if it blinked, and the timer on top is too small to catch at a glance. So, what I need to do is pick up my iphone, bring it close to hear the beep and/or see the reset clock actually reset. When I'm fatigued, sweaty, and to just want to press the button and continue my workout without slowing down, I am not able to... and stopping or slowing down disrupts the workout tempo.
SOLUTION: Please update this app. to where the whole screen blinks "green" or any color, when the "lap" button is pressed. This will provide a larger stimulus and I don't have to second guess to see if the "lap" button was pressed. I think that will solve the problem, and I am looking forward to re-rating this app. a perfect 5 star!
