Condition Forecast

The Condition Forecast ("tomorrow's prep") in Feelmo Premium weaves in tonight's sleep to gently look ahead at the next morning you'll wake into, and estimate its balance. It appears on Home as the "Tomorrow's forecast" card. After the overview in "Your morning balance and getting ready for tomorrow," this page unpacks how to read that card.

In one line

The Condition Forecast is a "weather forecast for your condition." Once tonight's measurements are in, it gently shows tomorrow morning's balance as a guide, with a range. It isn't a fortune-teller — it's a single card to help you prepare, just a little, for the day ahead.

What's shown

The "Tomorrow's forecast" card lays out the following.

Target-day chip (e.g. Tomorrow · Sun, Jun 29) — which morning this forecast is for
Tomorrow morning's Balance (forecast) — a rough 0–100 guide, with a likely range (e.g. 72, around 64–80)
A one-line read — the morning's mood in gentle words: "a calm outlook," "within your usual range," "a day that may waver a little," and so on
Five fragility bars — fatigue, focus, stress tolerance, mood swings, recovery
What it's based on, and the next update — e.g. "based on the Sat, Jul 5, 3:26 PM measurement · updates after tonight's measurement"

"Tomorrow" gradually becomes "Today"

The Condition Forecast always points at the next morning you'll wake into. That's why the card is headed "Tomorrow's forecast," and the chip reads "Tomorrow · Sun, Jun 29." Think of it as separate from today's balance (the big gauge on Home) — a card that looks ahead to the morning still to come.

And once midnight passes, the "tomorrow" you were looking at last night simply dawns as "today." The card even adds a soft note: "past midnight, 'tomorrow' quietly becomes 'today.'" You see "tomorrow's you" in advance, then live it as "today's you" once that morning arrives — that's how it's built.

Numbers refresh only "after tonight's measurement"

Even when the date rolls over and "tomorrow" grows into "today," that alone doesn't change the forecast numbers themselves. They refresh only after you wear your Apple Watch to sleep tonight and that measurement comes in (by tomorrow morning).

"Based on" and "Next update"

Below the card, the date and time of the measurement it rests on and roughly when it will refresh next are written together on one line (e.g. "based on the Sat, Jul 5, 3:26 PM measurement · updates after tonight's measurement"), so you can see at a glance which night's state it's reading.

On thin-data days, it quietly rests

On days when the data is thin — from a late night or interrupted measurement — Feelmo deliberately holds back the forecast. On days like that, the "Tomorrow's forecast" card may not appear, or may be more muted. That's because we value being able to say "today, I don't know" over forcing a verdict out of vague data. Wear your Apple Watch to sleep tonight, and a fresh forecast arrives again.

Reading the fragility bars

For five facets (fatigue, focus, stress tolerance, mood swings, recovery), the bar length is a gentle guide to where you may be more likely to slip on the day ahead. The longer the bar, the more it's worth taking it easy — a note to self, not a fortune. On higher-fragility days, use it to prepare: don't over-pack the day, slip in a breathing session, rest earlier.

Whether a habit actually moves your own balance can be checked in the habit-impact analysis — Which habits help you, in the Kokoro Report's "This week's insight" (Premium).

Your tendency calendar, ahead

Where the Condition Forecast looks ahead to the very next morning, the tendency calendar gently lights up the days beyond that. It's the weekday-tendency band shown inside the Premium condition forecast card — part of Feelmo Premium, not a separate free screen.

The tendency calendar isn't a guessing game. It lays out bands that rise from your day-of-week rhythm and your own baseline.

What's drawn isn't a score but a band — "around here you tend to be balanced, or to waver." It never declares "on day N you'll be N points"
The farther out the day, the wider and fainter the band grows — an honest sign that the further ahead we look, the less certain anything is
This is a tendency, not a prediction. It's only there to gently sketch "your tendency," ahead
It's drawn only once enough nights (about 15 nights over ~3 weeks) have gathered. Until then, it won't force a line

Forecast vs. tendency calendar

"Getting ready for tomorrow" (the Condition Forecast) gives you the very next morning's outlook, in Feelmo Premium. The "tendency calendar" — folded into that same Premium forecast card — shows the gentle tendency of the days beyond. Close in, in detail; far out, held back — that's how Feelmo looks ahead.

Please note

The Condition Forecast is a forecast of your own within-person (N-of-1) tendency, not a medical prediction or diagnosis. Feelmo is not a medical device and does not diagnose or treat. If you have any concern about your health, please consult a medical professional, regardless of the forecast or the numbers.
