Which option to choose?

Question

Mobile development

Hello! I want to create a mobile application for the main types of platforms. The essence of the application: during installation, a person chooses at what time it is convenient for him to receive a notification, and in the process of using it can change this time. Then he will receive one notification per day. When opened, the message will be available for 30 seconds. The app will be ad-free. Need advice on which of the existing methods is best to choose for the implementation of this application? Himself with programming for you.
