How to see which apps eat your day on a Mac
· 6 min read
macOS already has a per-app usage report in System Settings under Screen Time, and for a first look it is enough: turn on App & Website Activity today and read the list tomorrow. If you want a record that covers only the working day and arrives on its own at closing time rather than one you have to go and find, a menu bar app like Punchcard prints a daily receipt itemized by app. Both methods are described below, with the limits of each.
Method one: Screen Time
Screen Time on the Mac is the same feature as on the iPhone, and it reports app usage per day and per week. Nothing is recorded until you switch it on, so do that first.
- Open System Settings from the Apple menu.
- Choose Screen Time in the sidebar.
- Turn on App & Website Activity. If it is already on, you will have data from whenever it was enabled.
- Wait a day, then come back to Screen Time and open App & Website Activity.
- The top of the view shows a bar chart of the day, with the day total above it. Below is the list of apps, ranked by time, with a bar for each.
- Use the control at the top to switch between Today and This Week. The week view shows the same list totaled across seven days.
That is the whole procedure. If you use more than one Apple device with the same account, the report may combine them; look for the device selector if the numbers seem higher than your Mac alone would explain.
Reading the Screen Time list
The list is ranked by time, so the top three entries are your answer to “which apps eat my day”. A few things to keep in mind while reading.
Websites appear as their own entries under the browser, which is useful if the browser is at the top and you want to know why. It also means the report knows which sites you visited, which some people would rather it did not; that is a trade you are making for the detail.
The totals run around the clock. A Mac used in the evening will show evening apps in the same list as daytime ones, and the week view includes the weekend. If you want the workday only, read the Today view at the same time each day, just before you stop, and write the top three down. That gives you a rough workday snapshot without the evening mixed in.
Categories (Productivity, Social, and so on) are assigned by Apple and are not always how you would sort things. Ignore the category totals and read the app list directly.
Where Screen Time falls short for work
Screen Time answers “how much did I use this Mac” well and “where did my workday go” less well, for four reasons.
It has no idea when your day starts or ends, so every total needs mental subtraction. It includes everything, work and not, and cannot be told which is which. It has to be visited; there is no moment at which the day’s answer is delivered to you, so most people check twice and then stop. And its history is short, so it is hard to compare this week with a month ago.
None of these are defects; they are the result of the feature being built for a different question. If the question you have is specifically about the working day, there is a more direct tool.

Method two: a daily receipt
Punchcard is a Mac menu bar app from Everyday Mac Tools built around the workday version of this question. It notices which application is in front during the day and, at the closing time you set, prints a receipt: one line per app with its time, a day total, and a stamp, on paper that feeds out of a slot over a couple of seconds. You tear it off by dragging down.
- Download it from the product page, open it, and pick a closing time. There is no setup beyond that: no account, no projects, no timers to start.
- Work the day as usual. The app records which app is in front, by name only.
- At the closing time, the receipt prints. Read the top three lines. That is your answer for today.
- Tear it off. Export as a PNG if you want to keep it, or copy the plain text into a note.
- On Sunday, read the week roll for the same list totaled over the week.
The receipt is delivered rather than visited, which is the practical difference from Screen Time. It is scoped to your working day because it stops at the closing time. And it sees considerably less than Screen Time does: app names only, never window titles, document names, URLs or sites. It asks for no macOS permissions, and it contains no networking code, so the record stays in a single SQLite file in your Library folder where you can export it as CSV or delete it entirely.
The first seven receipts are free, and tracking never stops being free. After seven, a license is a one-time nine dollars for two Macs.
What “the app in front” does and does not mean
Both methods measure the same thing: which app had the front window, and for how long. It helps to be precise about what that includes.
It includes time the app was in front while you were reading, thinking, or away. If you leave a document open and go to lunch, the document is credited with lunch. Punchcard has no idle settings to adjust, so this is simply something to read around. A line that seems too long for what you remember usually has a break inside it.
It does not include what you were doing inside the app. A browser at three hours could be research or news. An editor at four hours could be writing or rereading. Neither method knows, and neither claims to.
It does not distinguish projects. If two clients live in the same app, they share a line. Punchcard has no project or client tracking, so if per-client hours are what you need, you want a tracker with projects, and this is not the right tool.
What to do with the top three
Once you have the top three, by whichever method, the useful move is to check them against what you would have guessed.
If the top app is the one you think of as your real work, good; the day is shaped the way you intended, and the question becomes whether the second and third lines are too long. If the top app is communication, mail or chat or video, your day is shaped by other people’s requests, which may be the job or may be the problem. And if the top app is a surprise, something you did not think you used much, that is the finding, and the one most worth a week of watching.
Do not act on a single day. Run either method for five working days and read the top three across all of them; what is consistently at the top is the shape of your week. For reading a week of receipts together, what-a-week-of-workdays-looks-like-as-receipts.html goes into detail.
Questions
Does Screen Time cost anything or need installing?
No. It is part of macOS. You only need to switch on App & Website Activity, and data starts from that moment, not retroactively.
Can either method tell me which websites I was on?
Screen Time can; it lists sites under the browser. Punchcard cannot and does not try; it records the browser’s name and the time, nothing about what was in it. Which you prefer depends on whether you want that detail recorded on your Mac.
What if I use two Macs?
Screen Time may combine devices signed into the same account; check the device selector. Punchcard keeps a separate record on each Mac with no sync between them, so you would read two receipts. A license covers two Macs, but the records do not merge.
