Apps Advice on making to-do list / reminder app

[Castino]

If you were to make a to-do list / reminder app with notifications on a specific date/time - How would you make it? (A small step-by-step list would be very helpful) What tools/databases would you use? SQLite, WorkManager, AlarmManager or are there any better/easier ones?

As for database, it is recommended to use SQLite.
