This would be extremely useful for professionals who use smart watches :)As someone who used this app this morning, crucial seconds matter. Great App!

We use this app regularly at work. I wish there was also an app for the Apple Watch that you could have to aid in compressions.

I used this in a code at work and it was fantastic. Not only was it incredibly fast to get running, it also allowed me to keep track of how many cycles we had been running. The ability to monitor compression timing is a great feature as well. I've recommended everyone on my team get this app on their phones...great upgrade to just a typical basic timer.

Any txt file I open immediately opens in this app, even after I’ve taken away permissions. Please fix.
