Summary:
- The tracking experience was different than the prior assignment because of the longer time intervals. I also found it easier to track how much time I spent because of the screen time feature on my phone.
- On Sunday, I spent about 3 hrs and 30 minutes on my phone. On Monday, I spent a little over 3hrs on my phone.
- Surprisingly, I learned that I spend more time on my phone in the morning compared to the evening when I’m not in classes. I think that this is due to my early sleep schedule and also because I tend to spend more time with friends in the evening.
- Next time, I plan to set restrictions on certain apps to see how that impacts my overall screen time. I also plan to do more intervals (twice in the morning, twice in the afternoon, and twice in the evening) to gain a clearer understanding of my screen time habits and identify areas for improvement.
