What is ImageTracker?
ImageTracker turns changing web images into widgets. Add a JPEG or PNG image URL for a webcam, satellite view, or live chart, and your widget refreshes periodically with the latest image. Keep a favorite view on your iPhone or iPad Home Screen, or use widgets on a Mac with Apple Silicon.
Custom widget titles and image sharing are available with the paid upgrade.
It’s the spiritual successor to SlothCam, with all the features of the original and more.

The story behind ImageTracker
From Dashboard to your Home Screen.
ImageTracker’s story starts with SlothCam. I released it in 2005, in the early days of Mac OS X 10.4 Tiger, as one of the first Dashboard widgets. The idea was simple: bring a live webcam from somewhere in the world onto your Mac’s Dashboard.
A little widget on Apple’s front page.
Then SlothCam made it onto Apple.com. The June 2, 2005 snapshot below shows it at #3 in Apple’s “Top Widget Downloads,” just below My Yahoo! I remember it reaching #2 at one point. Seeing something I’d made on Apple’s homepage is still one of my favorite moments as a developer.

A window on the world, in Dashboard.
SlothCam let you choose a built-in webcam or enter your own image URL. Dashboard is now gone, but that simple idea has stayed with me. The SlothCam listing on MacUpdate preserves another piece of its history.
The SlothCam apps
From a widget to iOS, Mac, and Apple TV.
SlothCam grew into an iOS app and a native Mac app, with features along the way including iCloud sync and tvOS support. I built the Mac and iOS apps in Objective-C with Interface Builder. They were products of their time, and I learned a lot making them.
The iOS app is still available but has reached the end of its development. I removed the Mac app from the App Store when I could no longer support it.
ImageTracker · The next chapter
A fresh start in Swift.
I started ImageTracker to learn Swift and build a modern iOS Home Screen widget. That project grew into SlothCam’s spiritual successor: everything I loved about the original, with a modern foundation and new ways to enjoy the view.
Today that includes widgets on Apple Silicon Macs, a gallery of webcams, saved image histories, and time lapse videos you can share. The same curiosity that started SlothCam is still behind it.
