2026-09-02	Mi*****	Brilliant app. You can tell it was built by people who actually know what they're doing. If you want finer control than this, you're looking at iptables on a rooted Android - but that's a hassle. This just nails it.

2026-08-27	Ja*****	I agree with other reviews. Since the upgrade it is atrocious. The dns block lists do not work, blocked apps are not logged. Before this the app was flawless, probably the best app I've had.

2026-08-26	Em*****	Hello Developer. Please, is there any process or UID named "unknown" that connects to different IP in Rethink app logs? Please reply me. I want to know if I've got a deep hardware compromise. I have flashed my phone several times but this app named "unknown" keeps connecting to IP's mostly from my chrome browser, and its not even an app that I can uninstall.
