A Windows app that keeps a long-term history of how much CPU, memory, disk and network each application uses, stores it on your own PC, and explains what changed in plain words.
Free during the beta. No account, no sign-up.
Task Manager shows what is happening this second. When your PC felt slow yesterday, or has felt slower all month, that moment has passed. This app keeps the record, so you can look back.
CPU, memory, disk and network use for each application, kept on your PC. A program that runs as many processes, like a web browser, is counted as one application, so its total is not spread over dozens of rows.
By default it keeps per-minute detail for 14 days, hourly history for 90 days and daily history for two years. You can choose to keep less. A live view shows what is using the computer right now, grouped the same way.
What starts with Windows, what has changed in that list, and how long Windows took to start over the last 90 days. Boot times are shown next to startup changes, so you can see whether they happened at the same time. It does not claim that any one program added so many seconds to your boot, because that is not something it can measure.
Which applications used the most CPU, memory, disk and network in a week, and what changed in startup. You can step back to earlier weeks. It reports what was measured; it does not hand out verdicts or scores.
Numbers come with words that say what was measured and over what period. Where something could not be measured, for example a protected system process Windows does not let it read, it says that the data is partial instead of guessing.
What it measures about your PC stays on your PC. The background service that does the measuring never connects to the network. The one connection the app makes is a daily update check, described below and in full on the privacy page.
No "issues found" counts, no red warnings about things that are normal, no countdowns and no fake urgency. If nothing needs your attention, it does not invent something.
It does not clean your registry, it does not promise to make your PC faster, and it does not change your settings. It shows you what has been happening so that you can decide what, if anything, to do about it.
A tool that watches performance should not become a performance problem. The service holds itself to written limits on CPU, memory and disk use, measures itself against them, and shows you the readings. The limits are listed under system requirements.
Everything it measures stays on your PC. No measurements, statistics or lists of programs are uploaded. It does not record file contents, browser history, web addresses, keystrokes or screenshots. For network use it records how many bytes each application sent and received, never where they went.
Once a day it asks its update server whether a newer version exists. The request contains the version number and, unless you turn it off, a random install ID. Nothing else: no hardware details, no usage data, no cookies. You can turn the check off in Settings, and with it off the app makes no network connections at all.
The app has two parts: a background service that takes the measurements, and a dashboard you open when you want to look. The service has to run in the background, because a history can only be kept if something is recording while you are not looking.
The figures in the table are the limits the service is held to, not marketing claims or averages from someone else's PC. The service measures its own use against them, and the dashboard shows those readings, including which of the two modes they were taken in.
| Resource | Limit |
|---|---|
| CPU, in the background | under 0.5% of one CPU core, on average |
| CPU, while the dashboard is open | under 2% of one CPU core, on average |
| Memory | under 80 MB |
| Disk writes | under 120 MB a day |
| History database | under 200 MB with full history kept |
Yes. Nothing in the beta asks for payment or an account.
Only the daily update check. It is one HTTPS request containing the app's version number, for example 1.2.0, and, unless you turned it off, this PC's install ID: a random number created on your PC, not derived from your hardware or your name. Like any request on the internet, it also reveals your IP address and the time.
Nothing about what you run, how your PC performs or what is on it is sent. The privacy page lists exactly what the server keeps and for how long.
Yes. When you install, you choose whether updates install by themselves, and whether the install ID is sent. Both boxes are ticked to start with, and you can untick them. In Settings you can change either at any time, or turn off the update check entirely. With the check off, the app makes no network connections at all.
An administrator can also turn update checks off for the whole PC with a policy setting, described on the privacy page.
An automatic update installs in the background and waits until no dashboard window is open, so it does not close a window you are using. It only installs a file that is exactly the version that was published; anything else is deleted without being run.
Like any other program: in Windows Settings, go to Apps, then Installed apps, find it in the list and choose Uninstall. This removes the program, the background service, the daily update task and the install ID.
Your history is kept on disk, so reinstalling picks up where it left off. If you want it gone too, delete the folder C:\ProgramData\PcHealth after uninstalling. Windows will ask for administrator rights, because the folder is protected so that other accounts on the PC cannot read your history.
It is built not to. The limits it is held to are in the system requirements, and the dashboard shows what the service is actually using on your PC, so you do not have to take our word for it.
It works, but it is not finished. Some numbers may be wrong, some features are still missing, and things will change between versions. Updates arrive through the daily check.
If it crashes, a number looks wrong, or something seems off, the app's Settings page has a "Report a problem" section that says where to write and can copy diagnostics for you to paste into a message. The diagnostics are shown in full before you copy them, and they contain nothing about which programs you run.
