Answer:
I dont think it will help much
Step-by-step explanation:
Well, just tracking it will not necessarily make you stop. I would recommend putting app limits or downtime (if you have a mac). Also make a log. Write down how much time you need for different things, like 1 hour of free time, 5 hours of schoolwork. Also, make a schedule based off the things you put on your log.
I found doing this helped me reduce my time on screen and made me more productive.
