Alarm using Time Picker

[ChrisWard]

Hello Ani

That would either require your App to be on Screen 24/7, or it needs to be able to work in the Background (background service). There is an Extension that might help you achieve that:

Background Tasks extension [3.8 A]

I, Kumaraswamy, attest that I am the author of the Background Tasks extension, grant that the extension included in project is free and that MIT has a non-exclusive irrevocable license to republish the extension as part of the project file for the purposes of the MIT App Inventor Appathon 2021.
