Support

If you have questions about Feelmo, want to report a bug, or have a request, please reach out to us here. We'll reply to each message, carefully, one at a time.

Feelmo is your everyday companion that gently watches over the balance of your autonomic nervous system. Our guiding principle is that we don't try to guess your feelings — we watch over how settled you are. That's exactly why we want to be a place you can turn to easily whenever it feels like that watching-over isn't quite working. Even if you find yourself wondering "is it okay to ask this?", please don't hold back — we'd love to hear from you.

Things worth trying first

Many questions are resolved by the "Common Issues and How to Fix Them" section below, or by the guide page On mornings when your balance doesn't arrive. If you're in a hurry, take a peek there first. And if something still lingers, the contact window below is always open.

How to Reach Us

  • Email: hello@feelmo.jp (it helps if you put "Feelmo" in the subject line)
  • Typical reply time: usually within 2 business days (Japanese / English)

When weekends or holidays fall in between, it may take us a little longer, but we read every message we receive. Please rest assured and wait for us.

When Reporting a Bug

To help us investigate smoothly, please include the following details where you can. You don't need to have all of them — whatever you know, even a single line, is perfectly fine.

  1. Your device (e.g., iPhone 15 Pro / Apple Watch Series 9)
  2. Your iOS / watchOS / Feelmo version
  3. What happened, and what you were doing at the time (steps to reproduce)
  4. Which tab it happened on (Home / Heart Journal / Breathing / Trends / Well-being)
  5. When it happened (a rough time is fine)
  6. A screenshot (if you're comfortable sharing one)

You don't need to send us the data itself

We don't need the contents of your HRV, sleep, or anything like that to investigate a bug. Feelmo's HRV-derived data and scores are, as a rule, handled inside your iPhone, and are never sent anywhere automatically. When you contact us, a glimpse of the screen (a screenshot) is usually more than enough.

Common Issues and How to Fix Them

My Balance score isn't showing

Your Balance score (0–100) is calculated from the HRV (heart rate variability — the subtle fluctuation between one heartbeat and the next) that your Apple Watch measures. At its core are multiple HRV-derived clues, measurement quality, and movement from your own baseline, indicators that reflect how settled your autonomic nervous system is. In other words, for it to appear, "HRV must be readable from your Watch" is a prerequisite. Please check, in this order, that the ingredients are in place.

  1. Are you sleeping while wearing your Apple Watch? — The score is born mainly from your heart rate and HRV during sleep. While you sleep there is little body movement, so the wrist sensor can read steadily. On a night you charge your Watch overnight, there's no data for that night. We recommend a rhythm of charging in the evening before bed, then keeping it on as you sleep. A loose band tends to miss beats, so try adjusting it to fit your wrist gently and snugly.
  2. Have you granted HealthKit permissions? — In iOS, go to "Settings → Privacy & Security → Health → Feelmo" and check that reading of Heart Rate Variability (HRV), Heart Rate, and Sleep is allowed. In particular, if Heart Rate Variability (HRV) is off, the Balance score itself can't be created.
  3. Is your sleep data being recorded? — In the Health app, check that not only your bedtime but also your sleep stages (the actual record of your sleep) remain. Also watch out for your Watch running out of battery.
  4. Have you opened the app once? — Even on a morning when the overnight processing didn't run, opening Feelmo will re-read on the spot and rebuild your Balance score. Open Home and wait a few dozen seconds; if it still says "waiting for data," try fully quitting the app and reopening it.

Even on a morning with no overnight data

If you make a little time during the day to "sit quietly," it becomes easier to read your HRV right then. Wrist measurement is sensitive to body movement, so a calm, seated state (on-demand measurement) gives the most honest reading.

By the way, the Balance score is meant to be read not against other people, but against your own baseline (your usual self). Low = wavering, high = settled — it's no more than a gentle guide. Rather than the number itself, we recommend gazing at the faces of the six companions placed beside it (Lively, Calm, Steady, Anxious, Frazzled, and Weary). For more on how to read it, please also see How to read your Balance, How your Balance grows, and On mornings when your balance doesn't arrive.

The numbers feel unsettled when I'm just starting out

When you first begin, your Balance score starts from a provisional display that borrows standard values, and the more your own data accumulates, the more it settles into your own baseline. It's completely natural for the numbers to feel unsteady for the first few days to about two weeks. It isn't a malfunction. For more, see How your Balance grows.

I want to change my HealthKit permissions

You can change them anytime, by data type, from iOS "Settings → Privacy & Security → Health → Feelmo." After turning a permission back on, just to be safe, open Feelmo once and let it re-read. The initial setup steps are explained in detail in Apple Watch and HealthKit.

Sleep, daylight, step count, and so on aren't showing

Your Well-being vital signs and habits (sleep, time in daylight, steps, respiratory rate) appear when each item is turned on in your Health sharing settings. In "Settings → Privacy & Security → Health → Feelmo," please check that reading is allowed for the relevant items.

  • Time in daylight is recorded on the Apple Watch side, and syncs to the iPhone a few times a day. It may show 0 during the day yet be reflected in the evening or at night (an Apple Watch running watchOS 10 or later is required).
  • These vital signs are daily signs, not a diagnosis. Don't let a single day's number decide things — look at the flow over time.

Premium features won't unlock / I want to carry over my purchase

Long-term trends (the whole Trends tab), the habit-impact analysis (Which habits help you), tomorrow's condition forecast, your autonomic trajectory, the Kokoro Report and its clinical-style PDF, habit trends over past days, the yearly (12-month) sleep view and the way back to past nights, and looking back at past days for daylight, steps, and respiratory rate are unlocked with Feelmo Premium. Today's Balance score and state, the six faces, basic breathing, today's habits, the weekly/monthly/yearly look-backs in your Heart Journal (all free), and the weekly and monthly sleep views stay free forever. Tapping a locked view — long-term trends, the yearly sleep view, a past-day look-back, and so on — brings up the purchase information (Paywall). For restoring a purchase, canceling, or refunds, see the FAQ section About purchases and restoring; for what the features include, see About Feelmo Premium.

Can I carry over my data when I change devices?

Feelmo's records (your Heart Journal, sleep, breathing, and the learned baseline values) are stored only on your device and are not saved to iCloud (our policy is to keep health-related data inside your device). Because of this, the records can't be moved directly to a new device, and after a device change your records start fresh on the new device.

  • Carrying over settings … When you turn on iCloud sync for settings, only your "settings" — notifications, display, reminders, and so on — sync with other devices on the same Apple ID (health data is not synced).
  • Source data … Source data like HRV and sleep accumulates in Apple's "Health" app. If you carry Health over to your new device, Feelmo will re-read from there on the new device and resume its calculations.
  • Premium purchases … As long as it's the same Apple ID, you can carry over your purchase by tapping "Restore" on the Feelmo Premium screen.

Notifications aren't arriving

In iOS "Settings → Notifications → Feelmo," check that notifications are allowed, and also check your Focus (Do Not Disturb) settings. On by default are the morning Balance score note (once a day), the daily reminder, the weekly report, and awareness alerts; only bedtime reminders and habit nudges are opt-in. The toggles for each type are explained in Notifications and reminders.

Requests & Feedback

"I'd love this feature," "this part is hard to use," "this wording doesn't quite sit right with me" — every voice is welcome. Feelmo cares deeply about staying close to each person's "usual rhythm." Our development team reads every piece of feedback we receive and uses it to nourish the balance we build going forward.

About Medical Consultations

Warning

Feelmo is not a medical device, and it does not diagnose or treat anything. The Balance score and vital sign displays are, after all, daily signs. We're unable to respond to consultations about your physical condition or symptoms, so if you have symptoms that concern you, please don't decide on your own — always consult a medical professional.
