I used to to time my watch up so now it’s to the millisecond and I tested this with iPhone alarm and other clocks it’s exactly right I totally recommend this plus the clock customization is always great!

This app is helpful but a little misleading. The clock appears limited to 0.017 second increments, only slightly better than Apple’s stopwatch app. Slo-mo video on the iPhone can capture at 240 fps, which would be 0.004 second precision. Filming this clock shows digits changing at 0.017 second increments. It would be wonderful to have a true millisecond clock for precision video analysis. Could a millisecond gauge be added? Can the phone’s internal clock actually support finer increments of time?

Great timer with tons of customization. Blinking : is always present

It’s a nice app. I upgraded to remove advs, but it did’t work. I used the restore purchases, but that didn’t work either. I feel like this is negative feedback … instead of a review. It would be nice if there was a widget, too. App dev is not easy … even with simple apps
