When someone sits down, it takes their photo.

Someone uses your Mac after it's been idle, tries the lock screen, or unlocks it. A second later there's a photo of them, with the time, how they got in, and how long they stayed.

A Mac desktop with the Someone Was Here panel open from its name-tag icon in the menu bar: the latest visit's photo of a man, marked Someone else, with a HELLO sticker reading 2:52 pm, and a list of earlier visits.

When it's you, it stays quiet.

It learns your face in a two-minute setup with a few head turns, and checks every photo right on your Mac. You won't get an alert about yourself.

The Someone Was Here panel open from the menu bar on a visit marked You, with a HELLO sticker reading You were here at 9:03 am, and Recognition: Matched your photos.

Then it tells you.

The photo reaches your iPhone within seconds, in the free Someone Was Here app. Nothing changes on screen while they're at your Mac. When it sees you again, your Mac tells you who came by.

The Someone Was Here iPhone app on its Visits screen: the latest photo, of a man at the Mac, marked Someone else with a HELLO sticker reading 4:05 pm, and earlier visits listed below.

It isn't hiding anything.

It sits in your menu bar where you can see it, and it's made for protecting your own Mac. If you share your space, tell people it's there.

The photo arrives in the free Someone Was Here app for iPhone, through your own iCloud. It also works with Pushover, ntfy, Telegram or a webhook.
