Good potential for debugging on iOS

I’m trying to get a setup where I can debug JS on an iPad Pro (I do like a challenge!) and this app is the closest I’ve come so far in finding an app that has a console. My only gripe is that it’s built for an iPhone and I would love it (and happily pay some £/$) if it supported iPad Pro 10.5 screens and had a little more advanced features.

Won’t work on htaccess (or similar) pages

This app would be more useful if it supported the htaccess login protocol. Other than this small issue it is still pretty useful.
