Simon 5 is coming soon!

Simon version 5 is currently in beta testing. 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 will be a paid upgrade from Simon 4 after the beta. Purchasers since September 1, 2020 automatically get a version 5 license (that also works in previous versions).

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 "http://www.apple.com/". Similarly, entering "dejal/simon" will end up as "http://www.dejal.com/simon/".
