Simon 5.0b2 released

Here is a second beta release of Simon, my website and server monitoring app for macOS.

Simon version 5 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, an iMessage notifier, and much more.

Version 5.0b2 includes an updated app icon in the Big Sur style:

New app icon

Plus other changes for improved Big Sur compatibility, a new Speak Error notifier, and sync improvements.

Please Note

  • This is an early beta release, with significant changes. Probably best to wait for the general release, unless you're keen. Use with caution!
  • If you find any issues with this beta release, please let me know!
  • Simon 5 requires a minimum of macOS 10.12 (Sierra).
  • Simon 5 will be a paid upgrade from Simon 4 after the beta period.
  • Purchasers since September 1, 2020 are eligible for a free upgrade; contact Dejal for details.

Read on for the full release notes:

Big Sur

  • Simon is now a universal app for Apple M1 silicon and Intel on Big Sur; it also supports back to Sierra (10.12).
  • Updated the app icon for the Big Sur squircle style.
  • Improved compatibility.

Added a new Speak Error notifier

  • This new notifier will read out loud the text of the last error that occurred.
  • Especially useful when a failure or recovery occurs, though can be used with any test result.


  • Improved the efficiency and reliability of syncing.

More coming later

  • I wanted to get a beta release out so brave people can begin kicking the tires. There is more planned for version 5.
  • Don't expect rapid updates; it will slowly improve over the next few months, and go into general release when deemed ready.
  • Please let me know of any issues you find via the contact form or the Dejal Subreddit.
