Semester Check-in Project

Track your semester mental health

A lightweight mood and wellness tracker that surfaces what actually affects your wellbeing.

6.1average mood (out of 10)

Over 28 days of check-ins, your average mood settled at 6.1/10, with 7.2 hours of sleep and an average stress of 5.0/10. But the averages only tell part of the story.

The semester began with a solid baseline. By the first week of check-ins, mood held steady at 6.6 and stress remained manageable at 4.7. Sleep averaged 7.5 hours — respectable for a college student. But the second week brought midterm preparations, and the numbers shifted.

By Week 2, stress had climbed to 5.6, while sleep dropped to 6.7 hours. The data showed beginning to emerge: by calculating the day-of-week averages, Tuesday stress averaged 8.5, the highest of any day.

The most striking pattern? . On days you went to the gym, mood averaged 7.0 — compared to just 5.6 on sedentary days. That is a 25% improvement. Social time showed a similar sweet spot: days with three or more hours of social interaction correlated with the highest mood scores.

By Week 4, the trend line was unmistakable. Mood climbed to 6.9, stress dropped to 4.4, and sleep recovered to 7.7 hours. The formula was simple but data-backed: gym, sleep, and social connection formed the triad of better mental health weeks.

“Better mental health weeks correlate with gym visits.” — a pattern your own data confirmed.
