How to keep a mood journal: a step by step guide for beginners

A mood journal, often called a mood tracker or emotion diary, is a regular record of the emotional tone of your days. Each entry is small: one value on a scale, and if you want, a tag or a single word next to it. Some people keep it as a table in a notebook, others in an app on their phone.

The goal is not to force yourself to feel good, it is to see what is actually there. Good days and bad days are equally valid entries, and both help you understand the week ahead.

The two are not rivals. Many people keep a short mood entry every day and save long writing for the days they feel like it. To compare digital methods, see our guide to the best way to keep a journal online.

Two lines of research support the habit. The first is about naming feelings. In an fMRI study published in Psychological Science in 2007, when participants put the emotion in negative images into words, the response of the amygdala and other limbic regions went down. Researchers call this affect labeling. Choosing a mood is exactly that, on a small scale: giving what you feel a name.

The second is about self-monitoring. In a 2018 study in the Journal of Affective Disorders, how much people engaged with a mood self-monitoring app predicted improvements in their mental health, and for depressed or anxious users the effect was explained by greater emotional self-awareness. It is a single study, so it is not proof, but it fits the idea that regular tracking builds awareness.

For a wider summary of the research, read our guide to the benefits of journaling.

1. 1Pick a moment. Make it the same time every day; for most people that is the evening, when the day is done. A fixed moment is more reliable than motivation.
2. 2Use a five level scale. For example Great, Good, Calm, Low, Rough. More levels make the choice harder and blur the comparison between entries.
3. 3Look at the whole day. Choose the overall tone, not a single moment. On a mixed day, mark what outweighed the rest.
4. 4Add context if you want. A one word tag such as sleep, work, exercise, a social day or your cycle is what explains the patterns later.
5. 5Leave a one word note. “Tired”, “meeting”, “beach”. A year from now it is enough to bring the day back.
6. 6Look back once a week. Spend five minutes on the past week's entries. Recording is half the work, looking is the other half.

If you prefer a notebook, this table is all you need. Each row is one day, and filling it in takes less than a minute.

Once a few weeks of entries have built up, ask these questions:

• Are weekdays different from weekends? If they are, you are seeing how the pace of work or school affects your mood.
• Which tags line up with which levels? Are exercise days brighter, are short sleep days heavier?
• Do hard days come in a row? An occasional hard day is normal; a run of them is a signal worth paying attention to.
• How does it change month to month? Seasons, holidays and busy periods suddenly stand out in a year view.

• Trying to measure everything. Tracking ten different things is exciting in week one and a burden by week three. Start with mood plus one or two pieces of context.
• Judging your entries. Marking a hard day is not a failure, it is honest data. The journal is there to help you see, not to grade you.
• Quitting after a missed day. A missed day stays empty, that is all. Pick up where you left off the next day.
• Only writing on bad days. If you only record the hard days, the picture looks darker than it is. Good days count too.

Pixmood brings this method to your phone. You mark your day by tapping one of five moods: Great, Good, Calm, Low or Rough. Each mood has its own color plus a second icon, so the scale works for color blind users too. If you want, you can add a one word tag of up to 20 characters, a note of up to 1,000 characters, a photo or a voice note of up to two minutes, all for free.

Insights are calculated on your phone. The free version shows basic insights for the last 30 days; Pixmood Pro adds 90, 180 and 365 day ranges, tag correlation and sleep, energy and productivity correlations. There is no account and no server; your journal lives in a local database on your phone.

You should know the limits too. Pixmood only lets you log today, so you cannot fill in a past day later. The daily entry has no writing prompts, and there are no AI features and no web version. If you are looking for long, guided writing, another tool may suit you better.

A mood journal is a self-observation tool; it does not diagnose anything and it does not replace treatment. If your entries have shown a heavy picture for a long time, take that seriously. The UK's National Health Service advises seeing a doctor if you have had symptoms of depression for most of the day, every day, for more than two weeks.

If you are having thoughts of harming yourself or you are in an emergency, ask for help right away by calling your local emergency number (112 in Türkiye and across the EU). Your journal entries can also make it easier to describe your recent weeks when you talk to a professional.
