Is there a similar organizer app?

Question

Android

Is there an Android application - organizer that meets the requirements:

1. open source
   
2. Simple text notes
   
3. Check lists, e.g. shopping list
   
4. Moving, copying elements between lists
   
5. Notifications can be attached to any note
   
6. Notifications can be repeated until they are read, for example, every 10 minutes
   

Google Keep is best suited, but it does not have clauses 1, 4 and 6.
Color Notes and Bzzapp were also considered from the analogues.
