On Mornings When Your Balance Doesn't Arrive
In the morning, your heart's balance score isn't showing up, or your companion (character) is still stuck as the "waiting for data" one — when that happens, here are the things we'd like you to check, gently and in order.
In most cases, this isn't a malfunction; it just means "the ingredients aren't ready yet." Feelmo is designed not to force a number out of a night that comes up short, so please don't worry if you have a blank morning now and then. Working down the list below usually turns up the cause.
How the balance score is made (a little about the mechanism first)
Your heart's balance score (0–100) is calculated from the HRV (heart rate variability — the fluctuation in the gaps between one heartbeat and the next) that your Apple Watch measures. At its center are multiple HRV-derived clues, measurement quality, and movement from your own baseline, indicators that reflect how settled your autonomic nervous system is.
- Low = a little unsettled, high = settled — a gentle rule of thumb.
- What matters is not comparing yourself to others. We read it as the difference from your own baseline (your usual self).
- Rather than the number itself, we translate it into the expressions of your 6 companions (Lively, Calm, Neutral, Anxious, Frazzled, and Tired) and place them alongside. We never make definitive claims.
In other words, the morning display assumes that "HRV can be read from your Watch." The checks below are the steps for confirming that those ingredients are in place.
First Things to Check
1. Were you wearing your Apple Watch while you slept?
The balance score is mainly calculated from your heart rate and HRV during sleep. While you're asleep there's little body movement, so the wrist sensor can read steadily (wrist measurement is vulnerable to body movement, and it's most stable when you're sitting still or in bed).
- If your Watch was charging overnight, there's no data for that night.
- We recommend a rhythm of finishing charging in the evening, before bed, and then sleeping with it on.
- A loose band makes it easier to miss beats. Try adjusting it so it fits your wrist gently.
When you want to check partway through the day too
Even on a morning with no nighttime data, if you make a little "sitting quietly" time during the day, Feelmo can read your HRV right then more easily. A calm, seated state (on-demand measurement) gives the most honest reading.
2. Is Health access enabled?
Settings → Privacy & Security → Health → Feelmo
Please check that the read access (permission for Feelmo to read the data) for the following items is turned on.
- Heart Rate Variability (HRV) — the core ingredient of the balance score. If this is off, the number can't be made.
- Heart Rate — used as a guide for resting heart rate and stress.
- Sleep — used to know "when you were asleep" so we can extract your nighttime HRV.
If even one is off, the morning display may be incomplete. After turning the permissions back on, please open Feelmo once just to be safe so it can re-read the data. For detailed first-time setup, head to Apple Watch and HealthKit.
3. Have you opened the app once?
Even on a morning when the overnight processing didn't run, opening Feelmo will re-read the data on the spot and reassemble your balance score.
- Open the home screen and try waiting for a few dozen seconds.
- If it's still stuck on "waiting for data," fully quit the app (swipe up in the app switcher) and reopen it — loading will start again.
- Toggling Airplane Mode on and off, and confirming that your Watch and iPhone are paired with the same Apple ID, are also worth checking just to be safe.
When There's a Display, but It's Different from Usual
A "low confidence" indicator appears
This is an honest sign that the data that night was a little sparse or scattered. It's not a malfunction.
- When tossing and turning or a loose fit keeps beats from being picked up well, the data becomes scattered, and HRV sometimes can't be calculated steadily.
- Please take the number from a low-confidence night as a rough reference only. For that day, reading your companion's expression a little more lightly is just about right.
- If you're wearing it snugly the next morning, things usually return to the normal display.
Some nights have no number
Feelmo won't force a number out of a night with too little data. Having nights with no number is proof that it's working honestly, without faking anything.
- A gap of a day or two might be a sign that your rhythm was thrown off, or it might just be that the fit was loose. Either way, there's no need to blame yourself.
- Only when there's no number for several days in a row, please retrace the "First Things to Check" above.
When it's higher or lower than usual
Even if a number looks like it moved a lot, that isn't necessarily because of how you're feeling. After a night with short sleep, a night you had a drink, or a night with a loose fit, HRV tends to come out differently than usual. Don't decide everything from a single number; when you watch it as a trend over several days, your own rhythm comes into view. For the longer-term flow, please also see Until Your Balance Grows In.
When It Still Doesn't Arrive
- If you record sleep with another app: depending on the format of the sleep data, it may not be readable. Please check whether "sleep stages" (a record of your actual sleep, not just the time you went to bed) remains in the Health app.
- Update your software: try bringing iOS, watchOS, and Feelmo each up to the latest version. With an old combination, HealthKit data sometimes doesn't pass through properly.
- Take the Watch off and put it back on once: wiping away dust or sweat between the sensor face and your wrist can sometimes steady the reading.
- If that still doesn't solve it, please feel free to reach out from Support. No matter how small the issue, it's fine to ask.
The first few days are "growing-in time"
At first, your balance score starts from a provisional display that borrows standard values, and the more your data accumulates, the more it settles into your own baseline. It's natural for the numbers to be unsteady for the first few days. For details, head to Until Your Balance Grows In.
Your data stays on your device
Your balance score and HRV-derived data are, as a rule, handled inside your iPhone, and they aren't sent off somewhere without your knowledge. You can delete them anytime. Please use Feelmo with peace of mind, as a companion for your everyday.
One thing, though
Data not arriving is a separate matter from how you're actually feeling. Feelmo is not a medical device, and it does not diagnose or treat anything. What it shows is only a day-to-day sign. If you have symptoms that concern you, please don't judge on your own — consult a medical professional.
