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.

How can I check that a Notifier is set up correctly?

You can quickly test any notifier by clicking the Notify Now toolbar button in the Notifiers window. It will perform the notification with placeholder variable values, so for the E-mail notifer, it will send the message, if set up correctly.
