Daylio tracks your mood. Hyperfix tracks what's causing it.
Daylio is a well-designed micro-journal. You log your mood, you pick your activities, you build a streak. Over time it shows you patterns — what activities correlate with which moods, which days are harder, where your energy goes. For what it's designed to do, it does it well.
But when you're on day 47 of a hyperfixation and you log "unwell" as your mood and "reading fanfic" as your activity, Daylio doesn't know what that means. It doesn't know that this specific fic is the thing. It doesn't have a counter. It doesn't have an intensity meter. It can't write the eulogy when it ends. It just logs the data point and moves on.
A mood journal logs the symptom. Hyperfix tracks the cause.
Daylio's model is: you were here, you felt this, you did these things. It's a record of states and activities. The insight is in the aggregate — patterns over weeks and months. It works by accumulating data points until trends emerge.
A hyperfixation isn't a data point. It's an era. Day 47 isn't a mood entry — it's a number that means something. The intensity meter isn't a mood rating — it's a live reading of something that's still happening. Hyperfix is built for the specificity of one thing consuming you, not the aggregate of many things happening.
What Daylio Does Well
Mood tracking
Daylio's mood correlation over time is genuinely useful. If you want to understand the relationship between your activities and your emotional state across months, Daylio's charts and patterns are built for that.
The streak
Daylio's daily logging streak is a real behaviour design win. The habit of checking in, logging the day, maintaining the streak — it works for people who respond well to streaks, and many do.
Simplicity
Daylio's logging flow is fast. Tap mood, tap activities, done. For people who want a minimal check-in that doesn't take more than thirty seconds, it's hard to beat.

Daylio is a good mood journal. Hyperfix is for the specific, consuming, named thing that's running your life right now.
Your mood was 'good'.
What you didn't log was why.
Daylio has 847 entries. You've been consistent. The charts show that you're happier on weekends and that "reading" correlates with better mood. What the charts don't show is that "reading" for eleven weeks was one specific fic. That the mood was good because of it. That when it ended, the mood dipped for four days and you didn't know why until you realised you'd finished the thing and there wasn't another one. None of that is in Daylio. The data is there. The meaning isn't.
Log the thing. Not just the mood.
