Introducing Simon 5!

Simon version 5 is now available. It is a massive update, introducing a much-requested feature: syncing the Simon data between multiple Macs, plus a Simon Status service, a Link Checker filter, improved Find filter, iMessage and Speak Error notifiers, a new app icon, and much more.

Important: please note that Simon 5 requires a minimum of macOS 10.12 (Sierra), and is a paid upgrade from Simon 4. Purchasers since September 1, 2020 automatically get a version 5 license (that also works in previous versions).

Read the Simon What's New page for details.

Is there a shortcut to enter URLs for Web (HTTP) tests?

Yes, you can enter URLs with very minimal text, and Simon will fill in the rest when you click OK. It automatically adds the default protocol ("http://") and the "www." and ".com" if necessary.

For example, typing "apple" (without the quotes) will be saved as "". Similarly, entering "dejal/simon" will end up as "".
