How to track your mood
A daily check-in can stay simple: name the feeling, locate its energy and pleasantness, add one line of context, then wait for a weekly review before drawing conclusions.
The short version
- Check in once a dayUse a reliable cue, not a perfect time.
- Name the closest feelingStart with energy and pleasantness.
- Add only useful detailIntensity is optional; one context line is enough.
- Review mood patterns laterCompare several entries once a week.

When to check in
Attach a daily mood check-in to a cue that already happens: after dinner, when you close your laptop, or before you plug in your phone. A repeatable cue is more useful than chasing the exact same minute.
Answer for the moment you are in, rather than trying to calculate an average for the entire day. If you miss a day, continue with the next one. The mood log is still useful even when a streak changes.
Name a precise feeling
Start with two questions: how much energy is present, and how pleasant or unpleasant does the moment feel? High energy can be anxious or excited; low energy can be drained or peaceful. The combination narrows the vocabulary without asking you to know the right word first.
Use the closest phrase, not the perfect one. Mental’s interactive emotion grid places 49 everyday phrases across those two dimensions, so you can compare neighbouring choices.
Intensity and context are optional
An intensity score can help distinguish “present in the background” from “hard to ignore,” but it is not a grade and you do not need one every day. If numbers make the check-in feel rigid, leave them out.
Add only enough context to make the entry recognisable later: “slept badly,” “quiet afternoon with friends,” or “deadline moved.” Record what happened, not a complete explanation of why you felt it. If one factor matters to you, tag it consistently instead of tracking everything at once.
Worked example

- Feeling
- Anxious, tense
- Energy and pleasantness
- High energy, unpleasant
- Intensity
- 7/10 (optional)
- Context
- Sent the proposal after three hours of revisions.
This entry describes one moment. During the weekly review, it can be compared with other entries instead of being interpreted on its own.
Entries can also be a few words, a corrected label, or a note added later. See eight finished fictional entries and what each leaves unknown for a wider range.
What one day cannot tell you
A single entry is a snapshot, not a verdict about your personality, week, relationship, or health. It cannot show a trend, establish that one event caused a feeling, or tell you what will happen next.
A gap in the mood log is also not evidence of a “bad” week. Treat missing entries as missing information and resume without filling them from memory.
Review mood patterns once a week
Set aside two minutes after several entries have accumulated. Look for repeated feelings, energy levels, and context — then write one question, not one conclusion. For example: “Three high-energy unpleasant entries followed long uninterrupted work sessions. Would a short break change anything next week?”
Keep alternative explanations open. Sleep, timing, expectations, and what you chose to record can all shape the pattern. Review again after another week before deciding it is stable.
See how a daily label can hide an earlier feeling in the fictional mood-chart reading lab. Compare individual check-ins, a daily summary, and context notes from the same fortnight.
When tracking becomes unhelpful
Simplify or pause if you repeatedly check for the “right” answer, judge yourself for a score, or spend more time measuring the day than living it. Try fewer fields, less frequent reviews, or a break from tracking.
If recording your mood increases distress, or you need help interpreting persistent changes, speak with an appropriately qualified health professional. A consumer mood tracker does not diagnose a condition or replace care.
Privacy, sharing, and export
Mood notes can contain sensitive details about you and other people. Record the least context you need. Before choosing any app, check where entries are stored, whether analytics include journal content, and what happens when optional cloud or AI features are enabled.
If you export or share a journal, review the file first, choose only the useful date range when possible, and remove names or details the recipient does not need. Mental lets you export your journal from the app. See how Mental handles journal data, then use the privacy policy for the exact terms.
Evidence and limitations
The energy-and-pleasantness frame follows James A. Russell’s circumplex model of affect. Repeated in-the-moment self-reports are related to ecological momentary assessment, a research method that records current states and context in everyday life; a systematic review of EMA validity research describes both its uses and the limits of self-report.
This guide is a low-burden personal practice, not a clinical EMA protocol. Research schedules often ask more frequently and are designed around specific questions. Once-daily entries are easier to sustain but capture fewer moments, and every self-report can be shaped by attention, memory, wording, and context.
The methodology and educational wording are maintained by Mental and reviewed when the product or underlying evidence changes.
Use the tool you will reopen
Paper works if you enjoy writing. A spreadsheet works if you want to design your own view. An app is useful when a quick check-in, reminders, and a visual history matter more than customisation.
Mental’s private iPhone mood tracker turns the method above into a short check-in: choose a feeling on the grid, add an optional note, and review the entries later. Read the privacy details first, then use the Mental App Store page if the method fits you.

If you have a moment in mind but cannot find a starting point, choose a question for the situation you are in, with a fictional first sentence to show one way into it.
For entries that go beyond a mood check-in, compare three ways to begin a journal entry: a sentence, a freewrite, or an observation and a question about the same day.
