Making charging time a clock instead of a tomato clock can be achieved by setting shortcut commands.
The specific steps are as follows:
Download the Minimalist Clock App on your iPhone and tap the shortcut command.
Once the shortcut is open, click Automation at the bottom of the screen and then click Create Personal Automation.
In the new automation screen that opens, select the charger.
Then in the open interface, check connected and click Next.
In the operation interface, click Add operation, enter Open in the search bar of the pop-up interface, and then select Open App.
Then click Select, and in the Select App screen that opens, select the Minimalist Clock App.
Once you've selected your App, click Next.
In the open interface, turn off the ask before running button, and then click Finish.
Set it inside the Tomato-clock, the Tomato-clock does not need to be set in the lock screen, so that the Tomato-clock will not be displayed when the phone is charging
