It takes about a minute. The app isn’t signed by Apple yet, so macOS warns you once, the first time you open it. Here is every click, with a picture of each.
It’s a Mac app, so it won’t run on a phone or tablet. Open wheredidmytimego.org on your Mac to download it.
Download for MacFree · 58 MB · macOS 11.0 or later · Intel and Apple SiliconOpen your Downloads folder. If the zip is still zipped, double-click it. Then drag Where Did My Time Go onto Applications in the sidebar, so it lives where your other apps do.
Open it from Applications. macOS stops it the first time, because it isn’t signed by Apple yet. Press Done, not Move to Trash. Trying once is what makes the button in the next step appear.
Open the Apple menu › System Settings, then click Privacy & Security in the sidebar on the left. Scroll the right side to the very bottom. Beside the line naming Where Did My Time Go, press Open Anyway. It stays for about an hour after you tried to open the app; if it’s gone, open the app again.
Use Touch ID or type your Mac’s password. If macOS asks once more whether to open it, press Open Anyway again. You only ever do this once.
The clock is up beside your battery. There’s no Dock icon, on purpose: it’s the only way a window can sit over a full-screen app. From now on it opens like any other app.
These are Apple’s own steps. Apple explains them, and why the warning exists, in Open a Mac app from an unknown developer.
Would rather check the file first? Fair enough. This is the SHA-256 of the zip I built, and the app makes no network connections at all, so you can point a firewall at it and watch it never ask.
