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).
Re: Does any of the Dejal applications monitor my Dynamic IP ...
Firstly, sorry for the delay in replying. As mentioned in the site-wide alert this week, I've been on vacation without internet access.
There are a couple of ways you could do this. If your machine is directly connected to the internet, you could use a Script-based service that uses the command:
ifconfig -a
Then use Smart Change Detection to notify you of any changes, perhaps filtering to a portion of the output.
If you're behind a NAT router (e.g. AirPort base station), you could use a Web-based test that checks http://www.whatismyip.com/automation/n09230945.asp — that URL will output just your IP address, so you don't need to use Smart Change Detection. This is probably the best option.
