Great app but iPad version has a bug...

The app does everything you could want for a dns debugging app (except quic support). But the iPad version has a bug where the + to add custom servers does not appear.

Crash

Works ok, I adde da custom dns server to test out, when trying to delete it the app crashes every time. Since it was only $.99 its not a big deal about it not the best app

Good good…

Scam

Don’t buy this. There is no connection when you run it.

Add but never be able to modify or remove DNS services?

This application comes preloaded with more than a few DNS services (Google, Cloudflare, etc.).

The user can also add additional DNS services with different options such as the IP, Name, Type (HTTPS, TCP,..). Very flexible indeed!

Unfortunately, there is no option to modify a user added service once the add button is pressed. No editable text files with the info could be located either by this user.

But there is an option to delete a user added service, so thats the trick right, just delete it and recreate it with new information = modify, right? Unfortunately this doesn't work and bombs the program immediately and brings up the ole 'crash report window' that gets sent to Apple, the developer, and all thier uncles of course. This was confirmed about 6/6 times on my M1 Macbook Pro. At least the 'reopen' button on the crash report window quickly reopened it each time. Bummer, but what did I expect? I got about 15 minutes out of this $0.99 app.
