Everyday Use

Feelmo isn't an app you have to work hard at. Wear your Apple Watch to sleep at night, and gently open the app in the morning — that's all it takes for your daily balance to quietly build up, day after day.

What Feelmo does is not "guess your emotions," but watch over how balanced your autonomic nervous system is (the principle of watching over your balance). So there's no need to search for the "right answer," or to brace yourself trying to raise a score. Here, we'll walk through a relaxed way of using Feelmo that follows the flow of a single day.

Morning — Receiving today's balance

When you wake up, open the app and take a look at the Home tab. At the center of the screen is the balance gauge, and beside it, one of your six companions stands ready to tell you about last night's bodily balance in gentle words.

How is it created? Your Balance score (Balance score) is calculated from the HRV (heart rate variability — the fluctuation in the intervals between heartbeats) that your Apple Watch reads. At the core are multiple HRV-derived clues, measurement quality, and movement from your own baseline, and from these we bring everything together into a continuous value from 0–100. The steady beats during sleep make the best material, so wearing the watch at night becomes the single morning snapshot.

How to read it?

• Please don't fixate on the number. To begin with, it's enough to simply, lightly receive which companion is here today
• Whether it's "Energized" or "Tired," that isn't good or bad — it's just a note about how you are right now
• The gauge carries an aura that shows how far you are from your own baseline. High or low isn't something to compare with others; read it as the difference from your usual self (What is a baseline)
• Home also lines up the vital signs cards (the latest values for HRV, resting heart rate, and sleep), the stress level, and the HRV trend. All of these are "daily signs," not diagnoses (more detailed vitals such as wrist temperature, respiratory rate, and blood oxygen (SpO₂) live on the Well-being tab; the colorful look-back at your recent moods lives on the Trends tab and in your Heart Record, not on Home)

Daytime — Your mood log fills itself in

Your Mood Log builds up on its own. Each day you wear the watch, that day's balance and mood are recorded automatically — there's no need to tap or type to keep it going.

• When something stirs in your heart, you can add a short note to the day. Your entry can be short, and it's completely fine to add nothing at all
• The balance and mood themselves are auto-judged and final — you can't change them, but a note is always yours to add
• Later, when laid over your body's balance, these records take on meaning as patterns unique to you
• From the calendar, charts, and recent logs, you can look back anytime

The trick is to keep your "how it felt" and your "body's fluctuations" as separate threads. Feelmo later lays the two over each other and gently brings to the surface "in what kinds of moments do I tend to become balanced, or to waver."

When you want to settle — Breathing

Feeling restless, shoulders tense — at times like these, head to the Breathing tab.

• Depending on your goal, you can choose a breath for calming down or a breath for lifting up, and follow the on-screen breathing pacer at your own rhythm. If you're unsure, start with a single calming session
• It doesn't guarantee an effect, but breathing is the simplest means of balance you can use to act on your autonomic nervous system right here, right now (Breathing sessions)

Looking back — Seeing trends by week and month

Rather than rejoicing or despairing over a single day's score, stepping back a little to take it in is the Feelmo way.

• With the Mood Log graphs, you can follow the shifts across week, month, and year
• In the Well-being tab, you can see habits like sun exposure, steps, respiratory rate, and sleep, along with the details of sleep and sun exposure
• "Lower-than-usual days have continued," "it tends to recover on weekends" — the trends themselves are the clues
• When you lay your behavior (sleep, sunlight, activity) over your balance, "what balances me" gradually comes into view (Connections with behavior)

Tips for keeping it up

• Don't aim for perfect. The record keeps itself; if some days carry no note of yours, that's perfectly fine. Feelmo affirms the "ordinary."
• Make wearing it at night a habit. Your balance is born from your heartbeat during sleep. The wrist is weak to body movement, so during sleep or a seated pause makes the most stable material. Charge during a short window in the daytime (Connecting with Apple Watch).
• Compare with yourself. Compare not with the person next to you, but with your usual self.
