Do you know of any Android/iOS app that keeps track of the current device IP and allows the user to send the IP via webhook (or anything alike) to a server? (alien.top)

Reason for my question is the following:
I want to host some services on my public server and while they all have normal password protection, I want to ensure the security a tiny bit more. Therefore I want to limit the access to the specific services through ufw and nginx to specific IP addresses. For my homeaddress I can use DYNDNS to get my current IP. However that will not work for my phone, when I'm on the go.
I don't want to constantly use vpn, as it slows down the speed of the internet connection significantly. Instead I would much prefer to just simply keep my server updated on my phones IP, so I can update the necessary config files through a script and thus allow my phone to access the services, where ever I am.

This is inventing security. Which is generally a bad idea. If you are worried about someone being able to hack you because their up isn't blocked you are saying that your security is wholly hinging on the thing that updates your allowed IP restriction. Which itself has no IP restriction (it can't cause how else would it work). And you are hoping that the security on that endpoint is WAAAAY better than something like a firewall
