Reading goals and read time tracker
Example: Apple Books
Design Draft:
Time tracking
Create a statistics database with a table Sessions(id, start, seconds, type, content_id). Add key-value setting for desired daily target with default = 15 minutes (900 seconds).
On launching a book, trigger a new session with the current date time.
On returning to home screen or app life cycle in [inactive, paused, detached], stop timer and save session to database.
Note: delegate inactive states to app life cycles instead of manually observing user behavior on the app.
On home screen, fetch Sessions with start time between 00.00 and 23.59.99 today. Sum all seconds for the total time read today. Sessions that go into the next day will be counted towards the day of the their start date. As such, it is possible to exceed 24 hours read time in one day.
Goals and Streaks
Add a table Goals(id, date, goal, total, session_ids)
On session creation to database, create new goal with date=today if such goal does not exist otherwise update such goal. Add session id to the goal and update towards the total. Update goal of today whenever user changes their goal.
On home screen streaks component, fetch all goals between start and end of current month. Get the percentage of goal completion by total/goal. On click each day, fetch all sessions by session_id.
Updating daily goal
When user updates daily goal, update both key-value setting of desired daily target as well as the goal row with date=today.
Note that goal setting is in seconds but displayed in minutes.
