With Just Timers you can set as many timers as you want, actively running at the same time. You can even reuse timers after they are finished.
Give your timer a name to make it easy to reuse later: Green Tea, Rice, Laundry
Control your timers with Siri Shortcuts. Just add an invocation phrase to a given Shortcut to quickly control your timers hands-free.
Quickly check your timers from the Today Widget on your lock screen. No need to open the app.
Looking for something a little friendlier on the eyes at night? Try out Dark Mode.
Just ask Siri to start a timer from your Apple Watch. It'll notify you on your wrist when it's done.
