It’s not an Android app but ServerCat is the best multi device monitoring/ssh software for mobile that I’ve come across. Sadly none of the alternatives on iOS or Android compare. Totally room for a proper competitor that fits a lot of information in an intuitive and clean ui.
If you like 1.1.1.1 the. You should try 9.9.9.9. Or better yet host unbound pihole if you’re up to the challenge. Best dns experience I’ve had.
