The “Reminder” app that comes with iOS is a so-called memorandum app. If you contact someone or write down what you need to buy, you will be notified and reminded at a specified time. It is also more rational than writing on the back of your hand that you should not forget when you leave the company or when you get home (geo fence function).
The reminder app has changed significantly in iOS 13. In addition to being able to attach photos and various documents easily, integration with the messaging app has progressed, such as being able to create reminders based on Siri suggestions while chatting.
The user interface has also been redesigned. Previously, you could only do color coding when creating a list, but with iOS 13 reminders you can now change not only the color but also the icon design.
For example, if you want to change the icon of the created list to green / shopping basket, tap the target list (orange / design is standard), tap the “…” button on the upper right of the screen, Select "Appearance" and select the icon design and color on the screen that appears.
There are 60 types of icon designs including default ones. If you change the color (12 colors), you can change it to 720 ways. You can decide how you want to use it, depending on the purpose, whether you want to share it with the person you are sharing, or up to you. Let's change into your favorite design.
