There is however you need to modify your adguard home / glinet router as there isn't actually any user on the custom integration. By modifying the adguard home installation you also will lose any insights you see from the glinet GUI, unless you visit the adguard home settings directly.
The app in question is this
And you will need to follow this guide
Also note, if you upgrade the firmware you will need to re-apply your adguard modifications.
I have tested the app and it works and you can manage lists etc however the adguard home gui is actually pretty responsive on mobile so I just create a shortcut to http://routerip:3000 and when prompted I login to my glinet gui which then redirects me to port 3000
Although I do think the app is a great addition I don't like the fact it makes some parts of glinet gui / glinet android not function correctly (displaying some stats) granted the 3rd party android app can display the stats and do more so for your usecase you might prefer it.
