"Simple Multi-Timer" is a simple, easy-to-read and easy-to-use timer application. Once you launch the app, just press the "+" button then set the timer time and press the "Start" button. You can also name the timer, and next time you want to set a timer, just select that name from the history. If you omit the name, it will be named automatically. For example, you can set the timer for 8 minutes and name it "Pasta (1.7 mm)”, or you can set the timer for 2 minutes and 50 seconds and name it "3-minute noodles" if you like cup noodles with hard noodles. You can also start a number of timers at the same time. For example, you can start a long timer for the oven or washing machine, and then start a short timer for pasta or cup noodles. The progress of each timer will be listed. Even if you interrupt or quit this application to use other applications, or if your iPhone automatically locks and goes into sleep mode, you can rest assured that you will be notified of the completion of each timer. This app also supports integration with shortcut apps, so you can start more and more timers from various automation such as shortcuts and NFC tags. It's very easy to use as a study or training timer, too. If you like it, let me know how you use yours in the comments!
