Helpful app

Clean interface, and the explanations of why apps go online are really helpful. Makes it easier to stay focused. Would love a quick way to disable all messengers during work hours.

Great App

I’ve been a happy Little Snitch user for a while, but I’m always eager to try Nektony’s apps they consistently deliver top quality solutions. When they released this new firewall, I knew I had to give it a shot, and I’m incredibly impressed. This app does everything I ever wanted from Little Snitch, and more. It’s wonderfully simple, It’s also much more efficient, using considerably less RAM – a great benefit if you’re running multiple apps! A really nice feature is being able to access blocked apps directly from within the app. I’m honestly blown away, I’ve already decided to discontinue my Little Snitch paid version. If I could add one feature, it would be the ability to block an app before it even opens. Highly recommended!

Thank you for your kind words! Your support and feedback are greatly appreciated. 💙
Could it be any better?

I really like this app. It has everything I wanted. The most important thing about it, compared to its counterparts, is how easy it is on CPU and RAM. It basically uses nothing. The fact that it is free shows the developers’ generosity. I appreciate all your hard work, my friend.Just a suggestion: I think there’s no need to have three separate columns 'real-time', 'hour', and 'today'. There could be just one column, perhaps called 'today', showing all the current processes.

Great review, thank you! 🤩 I’ll share your suggestion with the rest of the team.
Not seeing the app I want to filter
FranklinTankin
iOS simulator app doesn’t appear in this app’s interface, but I can see it connecting to the network. It would be nice if the app at least showed this traffic in an “uncategorized” field, but it doesn’t show up at all. Nice looking interface, wish it worked for my purposes.
