Getting Started

Feelmo is an iOS app for viewing Balance, a proprietary wellness summary based on available Apple Watch/HealthKit HRV-derived information and patterns in your own past records. It does not directly measure autonomic state, emotion, fatigue, recovery, or health. Six companion faces are product interface characters; their display rules are not public, and they do not infer how you actually feel.

This page walks you through setup and how to read the screens. At its core, you simply wear your Apple Watch and go about your day. Detailed display and update conditions are not public, and neither record availability nor time using the app guarantees an accurate Balance or forecast.

How Feelmo thinks

Feelmo compares a proprietary display with your own past rather than presenting a population cutoff. The processing details are not public. Your actual feelings, symptoms, and circumstances remain more important than a single score.

Requirements

  • An iPhone running iOS 17.0 or later
  • Reading your Balance score requires an Apple Watch and permitted compatible records in HealthKit
  • 11 languages are supported: Japanese, English, German, French, Spanish, Italian, Korean, Portuguese (Brazil), Thai, Simplified Chinese, and Traditional Chinese. The display language follows your device's settings (for details, see Supported Languages)

You can start without an Apple Watch

Some features work with just your iPhone, such as breathing exercises and reviewing the log. Balance uses available Apple Watch data. Processing and character-display rules are not public, and the product character is not an inferred mood.

Setup at a glance

1. Download Feelmo from the App Store

Get Feelmo from the App Store. After installing, open the app and follow the on-screen guidance. You can start without registering an account.

2. Allow access to HealthKit

The first time you launch the app, Feelmo explains and requests the HealthKit (Health app) access needed for core features such as Balance. If you later turn on an optional feature, it may explain and request an additional HealthKit item needed by that feature.

  • You can choose permissions item by item. It's fine to leave out only the ones you'd rather not share (the card for that item simply won't appear)
  • You can revoke or change permissions at any time from your iPhone, in "Settings → Privacy & Security → Health → Feelmo"
  • For details, see Connecting Apple Watch and HealthKit

Processing, sharing, and syncing are different

Feelmo processes HRV-derived data and Balance on device and does not automatically send them to Provider servers. If you start an export or share, selected content goes to your chosen destination. Apple Health and iCloud storage and syncing follow your Apple settings. See Data and Privacy.

3. At night, just wear your Apple Watch to sleep

Wrist readings may be easier to compare during sleep or while sitting still because large movement can interfere with measurement. These conditions do not guarantee an error-free or complete record.

When compatible HRV-derived information is available through Apple Watch / HealthKit, Feelmo can show its proprietary Balance display. Detailed processing and display rules are not public.

Your first morning

In the morning, the Home (Today) tab may show one of six product characters—Genki, Odayaka, Futsuu, Fuan, Panku, or Tsukare. Its display rules are not public, and it does not tell you how your body or mind actually was last night.

On Home, you can see things like:

  • The Balance gauge … an in-product reference for reviewing your record; its display rules are not public
  • Vital sign cards … available records for HRV, resting heart rate, and sleep. Consumer-wearable values can contain error or missing data and are not diagnoses (more detailed records such as wrist temperature, respiratory rate, and blood oxygen (SpO₂) appear on the Well-being tab)
  • A proprietary stress label, current HRV, and other app displays. The stress label does not directly measure perceived stress

There is no need to chase the number or interpret the character as your condition. Start with how you actually feel and use the screen as secondary information.

Read the score against "your own baseline"

Balance is not a number to compare with other people. Review your own records collected under reasonably similar conditions. “Learning” is an in-product state and does not mean that medical accuracy is being established. See Your Balance score and How baselines work.

How your Balance score works (in brief)

Balance (0–100) summarizes available HRV-derived information and patterns in your own past records with proprietary processing. Processing and display details are not public. It is not a measure of health, emotion, fatigue, stress, recovery, or medical normality. The six faces are product interface characters, not detected states.

What you can do in the first few days

Once setup is done, we recommend getting comfortable with Feelmo along the following flow. The bottom bar has four tabs (for a detailed map, see How to read the screens).

  • Home … today's Balance gauge, available wearable records, and product-specific reference displays. Guided breathing also opens full-screen from Home (Breathing Sessions)
  • Journal … Balance and a product character display may be saved for review. Their relationship and display rules are not public; your actual mood can be described in an optional note
  • Trends … the flow of Balance, HRV, and proprietary in-app labels from days to years; it is not an autonomic-function test
  • Well-being … sleep, sunlight, activity, and their association patterns with Balance on one screen; it does not prove an effect or causation

When you want to watch over yourself more deeply

On the current Free plan, today's Balance and face label, the six faces, the Mood Log (calendar), breathing (all six techniques), today's habits, and the weekly view are available at no charge.

When you want a longer look-back, Feelmo Premium adds the Condition Forecast, long-term trends, Habit Association Patterns that do not prove causation, a Kokoro Report for reference in conversations, a yearly review, and up to one year of history. Forecast processing and display conditions are not public, and it does not predict condition or symptoms.

This is not a medical diagnosis

Feelmo is not a medical device, and it is not intended for diagnosis or treatment decisions. Vital signs and your balance are "everyday signals" and do not determine the presence or absence of illness. If you have symptoms that concern you, always consult a medical professional.
