 · NOTE: Tested using Android client. TL;DR. On the client (Android), you should save Date/Timestamp in local timezone (use bltadwin.ru(), don’t need to get UTC time).

Since firestore does not have a "count" feature for all documents, and since I don't want to read all contacts to count how many contacts a user has, I trigger cloud functions when a contact is added or deleted which increments or decrements numberOfContacts in the user document. In order to make the function idempotent, it has to do multiple. Answer (1 of 2): Realtime updates can get expensive if you do it wrong.
