How to track your mood, and why it's worth doing
Tracking your mood means giving it a number from one to ten and a word once a day, since a short, consistent check-in reveals patterns a memory alone misses. In a 2026 JMIR Mental Health review of 8 randomized trials and 1,230 participants, Astill Wright and colleagues found mood monitoring alone did not reliably shift depression or bipolar symptoms, so its real value is the pattern it reveals, not a treatment effect.
Ask someone how they've been feeling lately and most people give one of three answers: fine, stressed, or tired. Not because that's the full picture, but because they genuinely haven't been paying close enough attention to know.
We move through our days reacting to things, but rarely pausing to notice the pattern underneath. What's actually affecting our mood? Is it getting better or worse over time? Are there particular times of day, particular situations, particular kinds of contact that reliably shift how we feel?
Mood tracking is simply the practice of checking in with yourself regularly enough to answer those questions.
Why tracking your mood matters more than it sounds
Mood tracking touches on a real strand of psychology research called interoception: your capacity to sense what's happening inside your own body, things like your heartbeat, breath and muscle tension. Neuroscientist Sarah Garfinkel, working with Hugo Critchley at the University of Sussex, has studied this in detail, including a narrower, related measure called interoceptive awareness: how well your confidence in reading your body matches how accurate you actually are (Garfinkel, Seth, Barrett, Suzuki and Critchley, Biological Psychology, 2015). In one striking study from the same research group, how accurately 18 male traders could count their own heartbeats predicted both their trading profitability and how many years they survived on a London trading floor (Kandasamy et al., Scientific Reports, 2016). It's a small, correlational, all-male sample, so it points to a link between body-awareness and performance under pressure, not proof that one causes the other.
Whether a daily mood check-in itself builds interoceptive awareness hasn't been tested directly, so we won't claim it does. What it does, more simply, is make you pause once a day and put a number or a word on how you feel, which is itself an act of attention you might otherwise skip.
Over time, patterns can emerge: connections between sleep and mood, between certain situations and your energy, between particular kinds of days and how you feel by evening. That's a different claim from saying tracking treats a mood problem on its own. A 2026 review of 8 randomized trials and 1,230 participants found that mood monitoring by itself did not reliably reduce symptoms of depression or bipolar disorder, and in one of those trials, 3 of 120 participants found the monitoring itself stressful (Astill Wright et al., JMIR Mental Health, 2026). Tracking is a way of gathering information about yourself, not a treatment, and it's worth knowing that going in.
How to track your mood simply
The simplest way to track your mood is once a day: give it a number from one to ten and one word that captures the quality of it. That's it. The whole thing takes thirty seconds.
Complexity is the enemy of consistency: a mood-tracking practice that asks a lot of you each time is easy to abandon, while a thirty-second check-in is easy to keep up. Signing up for something is its own kind of friction, which is why it's worth knowing you can use Solace's Mood Tracker with no account at all and start in the next thirty seconds.
The number gives you a trend line over time. The word gives you the texture: anxious and sad are both low numbers but they're different experiences that respond to different things.
If you're not sure which word fits, Solace's Feelings Wheel can help you find it, start broad and move outward until something lands, then bring that word here.
What to do with what you find
The point of tracking isn't the data itself. It's what you do with it. Once you can see a pattern, you can work with it.
If your mood is consistently lower on Sunday evenings, that's useful to know. If you notice that exercise reliably lifts your score by two points, that's something you can adjust for. If you see that a particular relationship or situation correlates with your worst days, that's something worth examining.
You don't need to track forever. Once a pattern is visible, whether that takes days or weeks depends on how variable your life is, you already have what you need to test a change. And once you know what you're working with, you can start making adjustments that are actually grounded in how you work, not how you think you should work.

Common questions
How do you track your mood simply?
Once a day, give your mood a number between one and ten plus a single word that captures its flavour, like flat, wired or content. No signup is needed: Solace's Mood Tracker works anonymously in about thirty seconds. If you're stuck on the word, the Feelings Wheel tool can help you land on one.
Why is tracking your mood worth doing?
Not as a stand-alone treatment: a 2026 meta-analysis of eight trials and over twelve hundred participants found mood monitoring alone doesn't move depression or bipolar symptoms by itself. What it does do is turn a vague sense of how you've been into something concrete, patterns in sleep, energy or certain situations worth adjusting for.
How long do you need to track your mood to see patterns?
There's no fixed timeline, and consistency matters more than duration. Regular, honest check-ins are what let a pattern surface at all, a repeating low point or a lift from a certain habit, and once you see one, you can test a small change and watch whether your numbers move.
This is what Mood Tracker was built for.
