1. the Android application of the To-Do type (very simple task list), to be used on smartphones by a closed group of logged-in users, a maximum of 5.
2. the database of records synchronizes between users in real time (the method of synchronization any, but it must be very stable and reliable)
3. the list of records is arranged only according to the order of creation. Any change to a single record (editing, commenting, etc.) gives it the newness parameter and refreshes them at the top of the list as "new".
4.In each user, only records created by himself and records that have been assigned to him by another user are displayed (assigned records have a record author tag)
5. each record can be edited only by the author of the record (change or delete it)
6) Each record after editing has the ability to add a comment, which will be displayed below the record in the form of an additional line in smaller font.
Individual comments are displayed one after another in lines
Something like a "shopping list" with real-time synchronization between users and a comment function next to individual records.
