Energy Forecast - KIRYOKU
Spot energy dips early
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Notice dips before they hit. First observations in 3 days, a measured hit rate that grows with your evening check-backs — your energy, read gently.
Read your energy like the weather.
KIRYOKU gently records your daily energy and shows you
today's forecast and the week's rhythm — quietly drawn from
your own notes.
Days when you tend to dip. Days when easing off helps.
How last night's sleep colored today. KIRYOKU helps you
notice your own waves when they're hard to see.
■ Today's forecast
A soft read of today's energy, based on your past entries.
"More likely to bounce back today" or "Today might be worth easing
into" — never a diagnosis, just a gentle morning hint.
■ Weekly rhythm forecast
A 7-day outlook by day of week. Notice that Tuesdays tend
to feel stronger, or Fridays tend to dip. Patterns surface,
gently.
■ First observations in 3 days
Three recorded days bring your first observations. Seven bring your week's wave, ten bring the forecast. No empty waiting.
■ Forecast check-backs
One evening tap: "How did today's forecast turn out?" As answers gather, reliability is shown as your real, measured hit rate.
■ Sleep signal (optional)
With Apple Health permission, last night's sleep is folded
into the forecast. "After shorter nights, energy tends to
slip" — drawn from your own records.
Processed entirely on this device. Nothing leaves your phone.
■ A gentle check-in
Log your energy with a soft slider — morning, afternoon,
night. Add a tag or a single line of note. "Rest Days" live
as their own kind of entry, so days you can't push through
still belong here.
■ Rest rhythm
See "rest days this month" and quiet signs when you haven't
paused in a while. A gentle brake for the part of you that
overdoes it.
■ Check-in feedback
Every time you log, the forecast grows a little. "Forecast
grew a little" or "Today looks a little easier to bounce back" — the input
immediately gives something back.
■ The month as a constellation
Your kept days line up beautifully. Rest days stay there, too.

The forecast is not a diagnosis or prediction — just a soft
tendency drawn from your own records.
Days you can't push through still belong here.
