State of Mind in Apple Health: a mood you log yourself, shown next to the weather

Not everything Apple Health holds about you comes from a sensor. Heart rate comes from your Watch. Blood oxygen comes from a sensor on your wrist. State of Mind comes from you: it is a record of how you say you feel, entered by you, at the moment you choose to enter it. This article is informational only — it is not medical advice, and nothing here diagnoses anything. The chain is short and worth stating plainly up front: you reflect and log how you're feeling, Apple Health stores that entry, and MeteoHealth reads it from HealthKit and shows it next to that day's weather. The app never decides how you feel. It never even guesses.

State of Mind is something you report, not something a sensor reads

Every other metric in this cluster starts with hardware. Apple Watch measures pulse rate against a plethysmographic signal; it estimates oxygen saturation from red and infrared light. State of Mind starts with nothing but you opening the Health app and choosing to reflect. Apple's own description of the feature makes the authorship explicit: "You can reflect on how you're feeling and log your momentary emotions and daily moods to keep track of your mental wellbeing" (Apple Support). Reflect, feeling, log — the verbs all point back at the user. There is no optical sensor for mood, and Apple doesn't pretend otherwise.

The feature is part of the Mental Wellbeing tools Apple introduced with iOS 17, iPadOS 17, and watchOS 10 in June 2023, and it has remained part of the Health app and the Mindfulness app on Apple Watch through iOS 18 and current releases. Apple's own announcement described it plainly: "New mental health features allow users to log their momentary emotions and daily moods, see valuable insights, and easily access assessments and resources" (Apple Newsroom). It is not a new iOS 18 feature — it has simply kept working, quietly, since 2023.

How you log it

Logging takes two forms. An emotion answers "How you feel right now" — a snapshot. A mood answers "How you've felt overall today" — a summary you can enter at the end of the day. In both cases, the entry starts the same way: you drag a slider from very unpleasant to very pleasant, choosing wherever on that range matches how you feel. Apple's newsroom description captures the interaction well: users "scroll through engaging, multidimensional shapes and choose how they are feeling in a range from Very Pleasant to Very Unpleasant. Then, they can select associations that are having the biggest impact on their feelings, like Travel or Family, and describe their feelings, such as Grateful or Worried" (Apple Newsroom). The words and associations are optional — you can log the slider position alone and stop there. Nothing about the flow infers anything on your behalf; every field is something you actively chose.

Why reflecting is the point

The feature isn't built to produce a number worth optimizing. It's built around the idea that naming a feeling has value on its own. Apple cites this directly in its research framing, quoting Dr. Michelle Craske of UCLA: "Identifying our feelings has been shown to help us manage difficult emotions, appreciate positive moments, and improve wellbeing" (Apple Newsroom). Apple frames the broader research the same way: "Research shows that reflecting on one's own mental state can help build emotional awareness and resilience" (Apple Newsroom).

Once you've logged a few entries, the Health app can also show correlations: "You can also learn how your state of mind may correlate with lifestyle factors like exercise, sleep, time in daylight, and mindful minutes" (Apple Support). Note the word may — a correlation, not a cause, and never framed as a target. There is no "good" mood score to chase and no "bad" one to fix. The value is in noticing your own pattern over time, the same modest, unranked framing this whole cluster has used for sleep, exercise, and heart data: something to observe, not something to win.

The assessments are screeners, not a diagnosis

Alongside logging, the Health app also offers optional standardized assessments. Apple describes them this way: "You can take age-appropriate standardized mental health assessments to answer questions about how you're feeling, and see your current risk for depression or anxiety" (Apple Support). These are the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 (GAD-7), two screeners used widely in clinical practice — but taking them in the Health app does not turn them into a clinical evaluation.

Apple is unambiguous about the limits here. On the results: "The results and resources are provided for informational purposes only and are not a substitute for advice provided by a doctor or other qualified health care professional" (Apple Support). And more directly still: "They are provided in the Health app for informational purposes only and the results are not a medical diagnosis. If you have concerns about your mental health, consult a clinician" (Apple Support). One line settles any ambiguity about what a score can and can't tell you: "The results may indicate whether you are at risk for depression or anxiety, but only a clinician can provide a diagnosis" (Apple Support). MeteoHealth doesn't touch these assessments or their results at all — they live entirely inside Apple's Health app, by design.

What you log, and what the app does

The provenance chain is short enough to say in one breath: you decide how you're feeling, you drag the slider and optionally pick words, Apple Health stores that entry, and MeteoHealth reads it — nothing more — through HealthKit. The app displays your logged state of mind next to that day's weather record. It does not measure your mood. It does not infer it from anything else in Health. It does not diagnose, screen, or score you. It shows you what you already told Apple Health, placed beside the pressure, temperature, or daylight for that same day, so you can look at the two side by side.

Where this fits in MeteoHealth

This is the point of the whole app: putting your own data next to the day's weather so a pattern, if one exists, becomes visible to you. With State of Mind, that means you might notice that your logged mood tends to dip on low-pressure, grey days, or holds steady regardless of forecast — but you are the one making that observation, not the app. Everything happens on your device; nothing about your mood entries leaves your phone. MeteoHealth never promotes a self-report into something more certain than it is — it stays exactly what it was when you logged it: your own word, on your own slider, on that particular day.

Bottom line

Across this cluster, three different levels of certainty sit side by side: Apple Watch measures and estimates certain signals directly from hardware; the app itself estimates others, like pulse, from the camera; and State of Mind belongs to a third category entirely — self-reported. You are the source, not a sensor and not an algorithm. The optional PHQ-9/GAD-7 assessments are informational screeners, not a diagnosis — only a clinician can provide a diagnosis. MeteoHealth's role stays exactly as narrow as it should: it reads what you logged in Apple Health and shows it next to the weather, nothing added, nothing inferred.
