What Review answers
Use Review when Overview tells you something changed and you need to know where the time went. It keeps the same active date range and filters, then gives you multiple ways to compare the same underlying data.
Which apps dominated?
Group by Apps to rank individual applications by duration, sessions, and share of time.
Which kind of work dominated?
Group by Categories to roll apps into buckets such as Development, Communication, Design, or Entertainment.
When did it happen?
Use the trend chart and heatmap to see whether time clustered on specific days or hours.
Choose app or category grouping
The first segmented control switches the Review screen between app-level and category-level analysis.
| Grouping | Shows | Use when |
|---|---|---|
| Apps | Individual apps such as Xcode, Safari, Slack, or Figma. | You want exact culprits, session counts, or a direct comparison between tools. |
| Categories | Your mapped category totals from Projects and Rules. | You want to compare types of activity instead of individual app names. |
If a category looks wrong, fix the app mapping in Projects + Rules. Review will update after the category mappings refresh.
Switch between Bar, Pie, and Trend
The second segmented control changes how the breakdown is drawn. The numbers are the same; the view changes the question you can answer fastest.
Bar
A ranked horizontal bar chart for the top apps or categories. Use it to compare duration quickly and spot large gaps between the first few rows.
Pie
A share-of-time donut for the biggest items, with remaining time folded into Other. Use it when proportion matters more than raw hours.
Trend
An area and line chart across the selected period. Use it to see whether usage rose steadily, spiked once, or stayed consistent.
Range label
The header repeats the active range and total time, so screenshots and exported notes stay understandable later.
Read the activity heatmap
The heatmap is a 7-by-24 grid: weekdays down the side, hours across the top. Darker or more saturated cells mean more recorded time in that weekday-hour slot.
Find the hot cells
Look for the darkest blocks first. These are the recurring hours where your Mac activity concentrates.
Compare weekday patterns
A bright Monday morning row says something different from a bright Saturday evening row. Use the row position as context.
Validate with Details
If a heatmap cell surprises you, open Details for the same range to inspect the exact sessions around that time.
Use the detailed breakdown table
The table is the source of truth for the chart above it. It includes every loaded app or category row, sorted by time.
| Field | How to interpret it |
|---|---|
| Rank | The row number after sorting by time. Rank changes when filters or granularity change. |
| Time | The total duration for that app or category inside the active period. |
| Sessions | Available on app rows. More sessions can mean more returns to the same app, not necessarily more total time. |
| Percent | The row's share of the current total. Percentages are best for comparing periods with different total durations. |
Thirty percent on a two-hour day is very different from thirty percent on a twelve-hour week. Always read the percent next to the total time in the header.
A practical Review workflow
- Pick Apps if you need specific tools; pick Categories if you need broader work buckets.
- Start with Bar to see the ranking.
- Switch to Pie when you need share of time.
- Switch to Trend when the timing of the change matters.
- Use the heatmap to find the day and hour to inspect in Details.
