Well done! Brilliant on the much needed update!

I slammed this developer for not updating this app. His response was to make it into this brilliant thing that actually live reads the network, to put it simply. So it doesn't just inspect the chain- it verifies all the magic!

Response from developer

Thank you so much for coming back and updating your review! I appreciated your honest feedback before, and I’m really glad you’re enjoying the update. Thanks for giving the app another chance

App works great, when I scan YouTube or YouTubekids.com it shows a bad cert. but iCloud is okay

More for apple in general but we need to do better and protect our kids. Again good functional app, I think there could be more features but with due time hopefully haha thank you for reading

UPDATE OR PULL! 😤

This app *used* to be handy- 4 years ago. Does NOT work with iOS 16. Come on devs, put this thing down.

MITM

The app worked great for a while now the MITM icon is greyed out even though the switch is green indicating it is active. I emailed the developer and after a few days no reply seems they are not interested in responding to paid subscribers.
