After taking a week off of my day job at lynda.com as well as any coding on Slower Shutter, I’m back at it.
I just enabled the option for you to set if you want a System Sound (specifically, the “calendar” sound) to play or if you want your iOS device to vibrate when the timer ends.
Next up, I’ll be trying to figure out how to keep the timer going while the app is in the background.
