Create toothbrush timer via NFC

Total time: 7 Minutes

With an NFC sticker, certain actions can be performed directly without touching the screen. This is especially useful for making regular tasks easier - like brushing your teeth. An NFC sticker attached next to the bathroom cabinet, can be used to automatically set a timer when the iPhone is held over the sticker. This saves time and also reminds you to brush your teeth for 2-3 minutes to keep them healthy. In this How2 we explain how this works by creating a shortcut and then writing it to an NFC sticker.

We create a shortcut by + Create shortcut and name it with toothbrush timer by clicking on the ... symbol at the top right. Now we tap on + → searching for timerStart timer. We tap on 30 and enter 2.5 (or another number of minutes).

Download the shortcut

Here you can download the finished shortcut, which then only needs to be saved on an NFC tag using NFC21 tools. Also downloaded shortcuts can be adjusted and changed afterwards in the Shortcuts app.


We programmed a short command and saved it on our NFC tag. By scanning the NFC tag, it automatically create a timer of 2.5 minutes. To let you know that the timer has been set, you will receive a notification when the timer has been set. With NFC21 Tools you can not only store short commands on an NFC tag, but also many other types of data. How this works is explained here.
