One score a slot, until your sharpest hours show themselves.
Log your energy from 1 to 10 in four time slots a day, then see your peak windows and plan demanding work when you are sharp.
-
Four slots, one number eachMorning, Afternoon, Evening and Night each take a single score from 1 to 10 and a note if something explains it. Logging a slot again replaces its score, so a day never fills with duplicates.
-
Peak windows by weekdayEight weeks of entries, grouped by weekday and slot, name your two strongest windows and your lowest, such as “Sat AM” and “Thu PM”, and say where to put deep work.
-
A week, a month, a yearHistory colours this week’s slots, October’s days and every day of the year by score, beside your logging streak and how often each slot gets a score.
Your first score
-
Tap a slot under “TODAY”
Or tap “+”. “Log energy” opens on the slot you are in now, which you can change under “TIME SLOT”.
-
Pick a number from 1 to 10
Add a note under “NOTE (OPTIONAL)” if one thing explains it, such as short sleep or a long walk.
-
Tap “Save”
The score becomes “RIGHT NOW”, with a name for the state, such as “Steady but limited”, and joins “RECENT HISTORY”.
Every step, in detail
- 1 Open Energy and tap a slot under "TODAY", such as "Morning", or tap "+".
- 2 In "Log energy", check the "TIME SLOT", pick a score from 1 to 10, and add a note if something explains it, like sleep or a workout.
- 3 Tap "Save". The score appears under "RIGHT NOW" and in "RECENT HISTORY", stamped with the slot's set time.
- 4 Log across different times of day for a week, then open "Insights" from the "..." menu.
One score a slot
Energy splits the day into four slots, Morning until 11:00, Afternoon until 17:00, Evening until 21:00, then Night, and asks for one number from 1 to 10 in each. RIGHT NOW is your latest; TODAY holds one row per slot. Log a slot again and its score is replaced, stamped at the slot’s set time rather than the minute you saved.
Sample · Tuesday, Oct 20 at 20:10, with Morning and Afternoon logged · tap a row, pick a score and save
The “+” and an empty row open Log energy at the slot the clock is in: Evening, at 20:10.

Where each entry lands
This morning’s 7 sits at 07:12 because it came from Start day, which keeps its own time, as Evening close does. RIGHT NOW is the latest entry by time, so a Night score saved now lands at 22:30 and takes over RIGHT NOW before the evening is out. A row with a score opens Log energy on that slot, with its score and note. Under TODAY, RECENT HISTORY charts the last fourteen entries and lists them as “N/10”; press and hold one there to delete it.
Where your peaks are
PEAK WINDOWS, in Insights, sorts the last eight weeks by weekday and slot, so every Wednesday morning is one group and every Thursday afternoon another, and averages each. A group needs two logs to count, and Night never does. The two highest and the lowest are your windows. Add scores and watch them move.
Sample · 110 logs from Aug 25 to Oct 20 · pick a score, then tap a cell to log it on that cell’s latest open day
Eight weeks, by weekday and slot
Night has 5 logs in these eight weeks. They count everywhere else, but never here.
PEAK WINDOWS
- Wed AM8.0peak
- Sat AM7.9strong
- Thu PM2.3lowest
Schedule deep work on Wed AM. Keep Thu PM for low-cognitive tasks.
The weekday bars average every log you have, 418 here, not just the eight weeks.
Sunday evening shows a 9 from a single log, the highest number on the grid, and it is not a window: one good evening can’t make a peak. Until some group has two logs, the card reads “Log one full week to unlock your strongest and weakest windows.”
The week, the month, the year
History reads the same entries back four ways: this week as a grid of slots, how steadily you log, the month as a calendar, and the year as one square a day. A day’s colour is its day score, the day’s entries averaged and rounded; the grid shows each slot on its own.
Sample · 418 entries from Mar 2 to Tuesday, Oct 20 · tap a day of October

2026 - YEAR IN PIXELS
THIS WEEK and SLOT COVERAGE leave Night out, as Peak windows do; the month, the year and the streak count it. Weeks start on Monday. Each card can be hidden in Energy Settings, and with all four off History reads “History view hidden”.
What Insights says at each score
Insights reads your latest entry and answers in two places: RIGHT NOW names the state and what it suits, and TODAY’S RECOMMENDATION gives one next step. Between 4 and 8 the step points at your best peak window, so it changes as your weeks fill in.
Sample · the latest entry is Afternoon 5 · drag to try another score

ENERGY DRIVERS
Log context tags with entries to see what lifts and drains your energy.
Log energy doesn’t take context tags yet, so Boosters and Drainers stay empty for now.
PEAK WINDOWS, from the section above, sits between the two cards at the top. The rhythm averages every entry by slot, Night included, and needs two slots logged. A week counts Monday to Sunday, so this week’s bar is two days in.
Outside the Energy page
Most scores never start on the Energy page. Today, Start day and Close day each ask for one, and Calendar shows them back beside the rest of your day.
-
Today’s ENERGY card
Shows today’s latest score, or “-”. A tap opens Log energy already set to the slot you are in; nothing is logged until you save. The ENERGY label opens the Energy page.
SLEEPAn optional row reads last night’s sleep from Apple Health. It shows in the Full and Minimal modes, and in Custom when you turn it on. -
Start day
Morning mode asks “How are you arriving today?” and saves your answer as a Morning entry, stamped with the time you answer. Once today has any energy entry, it reads “Energy already logged today” instead.
-
Close day
The evening close asks for a score too, and saves it as an Evening entry stamped with the time you close, alongside the rest of what you write there.
-
Calendar
The day timeline carries each entry as a card reading “ENERGY” and its score out of 10. In the week view, each day’s dot takes the colour of that day’s highest score.

Tips
- A peak window needs at least two entries for the same weekday and slot within 8 weeks, and Night is not counted. Log the same daytime slots for two weeks or more before you trust it.
- Use the note for the one thing that explains a score. A week later, "short sleep" or "long walk" tells you more than the number.
- Tap the "ENERGY" card on Today to open "Log energy" already set to the slot you are in, without opening the module.
Questions
About Energy day to day.
-
Why does my Night entry say 22:30?
An entry saved from “Log energy” is stamped with its slot’s set time, 8:30, 14:30, 19:30 or 22:30, not the minute you saved it. Scores from Start day and Close day keep the time you gave them.
-
When do peak windows appear?
Once a weekday and slot has at least two entries in the last 8 weeks. Until then, Insights reads “Log one full week to unlock your strongest and weakest windows.” Logging the same slots for two weeks or more gives it enough to compare.
-
Does Night count?
Not in peak windows, the weekly heat map or slot coverage, which cover the morning, afternoon and evening. Night scores still count in a day’s score, the month, the year in pixels and your streak.
-
Can I log the same slot twice in a day?
Logging a slot again from “Log energy” replaces that slot’s score and note. To remove an entry, press and hold it in “RECENT HISTORY” and tap “Delete entry”.
-
Does Energy use Apple Health?
Only for the optional Sleep row on Today, which reads last night’s sleep. Your energy scores are your own entries, and Energy does not write anything to Health.
-
Does it sync between my devices?
Your entries sync through iCloud with the rest of HourLife. Which cards Energy Settings shows is kept per device.

Today
The "ENERGY" card on Today shows your latest score, and a tap opens "Log energy" set to the current slot. Morning mode asks "How are you arriving today?", and the evening close saves an evening score.
-
Habits
Today's habits area carries an "ENERGY" row where you can log a slot, next to last night's sleep from Apple Health.
-
Calendar
Each energy entry appears as a card on that day in Calendar, and the week view tints each day's dot with its highest score.
