This is my first question here and my first experience with iOS. As a long-time Windows and Linux user, I have been asked to install a client (updater) for the dynamic DNS service nsupdate.info on a phone with iOS (current version).
I have researched the situation and came across RealDNS and some others, but none of them seems to be intended to work with nsupdate.info.
On Windows, it is the same, but I solved the problem there just by writing a script which performs the updates and which is triggered by the task scheduler on a regular basis.
But unfortunately, I don't have Apple's development tools, and I have no clue whether I could run a script on iOS at all, so I can't develop something myself. Plus, I have no knowledge of how to develop software for iOS (including scripts).
Could somebody help me out there? As a last resort, I could look into the list of providers RealDNS supports, and use one of these services. However, I'd like to know of other options (if any) before I do this.

nsupdate.info should work with any dyndns2-compatible client
You also can do quite a lot of scripting with the Shortcuts app (https://support.apple.com/guide/shortcuts/welcome/ios) which is part of iOS (you may need to download it from the Store in case you removed it in the past). There are actions to call any URL and to process JSON results.
