NoRoot Firewall

Love this app. it works great. The only EFE I have is a little more flexibility. The app sees all the IP addresses othe apps are trying to connect to and yoi can manually ad custom rules to allow acces to some IPs and deny others, but that can de tedious. When you review the IP addresses an app is trying to connect to your only option is to delete it. I wish there was a way to deny or allow individual ones in addition to just deleting them.

Does what it says and does it well. Some features that would help: 1. More precise notifications and the ability to disable them. 2. A way to label a server. It's hard to remember servers based on IP or even which aws server you meant to block (eg. to stop background stuff over true content) 3. A way to import block lists, through copy and paste or some other method.

Works very well overall. It says it may not work on LTE, but from what I've seen it does. Occasionally gets shut down at random on Android 5.1, but ironically it works flawlessly on Android 8.0. Has no ads. The only real disadvantage is since it uses the built-in VPN data channeling function, you cannot use an actual VPN at the same time as this firewall.

First off... awesome app. Thank you for providing it. But I can't ignore the stability issues. Sometimes all data flow seems to stop. I've found that it's due to NoRoot Firewall becoming unresponsive. Once I stop and restart the firewall, traffic resumes. That can take minutes, though, as NoRoot Firewall is apparently severely bogged down. I also find it frustrating that I can't (I assume) use a VPN service while running NoRoot Firewall. Aside from those issues... amazing app.

I use this to block ads on my games without turning wifi and data off. Works well and doesn't seem to slow things down. You'll have to take the time initially to let all your apps through, but after that it's nothing but useful. There may be an easy way to let everything through and then go and disable the specific apps but I'm too lazy to figure it out.

So far, it seems to work great for blocking ads on apps. However, the VPN is so slow that it won't even load the play store, so it almost puts it into airplane mode. I still need my messages come through when it's on. Def turn it off when not using it. Also, the notifications are constant (I mean every constant) for apps I haven't blocked accessing network, until you turn them off in Android settings. I don't need to know what unblocked apps are doing every second. It works,though.

Great firewall, I kept seeing a pop-up ad and didn't know what app it was coming from, tracked it down from logs and blocked it and don't see it anymore. I'm on a rooted Motorola One Zoom, no issues and only uses 48mb in ram. Would be amazing if the developer(s) can Implement numerous protocols of blocking, see "ProtoWall" for Windows XP which blocks over 30 protocols. Also, would be great if you can add a feature to add custom blocklists.

Does exactly what it says. Super easy (but tedious) control over every single outgoing IP connection. LOTS of room to improve, but I use it every day as-is, it works perfectly well, and I haven't found anything as straightforward that could replace it. After you've set enough custom rules, you barely even notice it's there. Eventually, it just turns into "Let's see how many things this new app is going to try to connect to".

Great app. Provides all of the functionality I need and more, and with a user-friendly and nice looking UI. I have used this app for a significant ammount of time, across 2 phones, and it has worked flawlessly. Unfortunately, I have to uninstall it because it does not function on Android 10. The non-beta version does not allow any connections whatsoever, despite wifi and cellular avalible. I have tried the beta version, but I encountered a strange issue (see my review on that app).

This app, viewed in a line up of all manner of system operation and maintenance applications, in my expert opinion, would be in the top 3 of all apps user installed and, a contender for the No.1 best. What's more it is unique in its operation as a "manually operated firewall." If you want to speed up your system, save wasted data time, free up space in your Ram, control what apps can access internet, quarantine apps to find the pop-up offender and more, this is the one you need. Near 0 adds too!

This app. is a helpful resource allowing the user to selectively filter the data stream of interference from unwelcome sources, screens out and identifies unlisted apps, and allows the user to exercise discretion over network &/or wi-fi usage by everyone (just yes or no, not how much though.) It takes a little thought & practice to use appropriately however, and it needs to be completely turned off while running downloads, uploads, etc. This tool is helpful, but not quite perfect.

Great app, a was searching for this app for a long time. I can easily prevent some apps from accessing the network making my phone more secure. Some apps are having a hidden capability to connect to the internet and do unwanted stuff. They all are pinned now. Adding later: the app doesn't start after phone reboot, although it is configured to start.

Nice app - wish it had a different setting for per app for when in use and when idle - some apps need network access to function but continue to send and collect data when idle. I have to enable permission each time I use those apps. But overall a great product especially the custom filters that you can set up right from the log file - for example you can disable access to the internet but enable network access on your LAN like if you have a NAS.

Used to be a fantastic app. Now it shuts down constantly without notice and doesn't start on boot. Very sad. There switch in the program's settings to "Block Connections without VPN." So theoretically when it shuts down it blocks everything. But since it glitches/shuts down, and Grey Shirts has no interest in the issue, I do not fully believe that I am protected when it shuts down. The only way you know it is shut down is when you try to directly access internet and get denied.

Works pretty well. Good for limiting background data usage and making you more aware of what apps are using the internet (even when you are not using them). However, if you are looking for a robust solution, this is probably not for you. I dig it though. It would be nice if there were a "firewall reset" button to make apps have to ask permission again and a single button (or drop down box) of various custom configurations. As it is, I find myself giving and revoking permissions often. Still, 👍

Recently reinstalled after not using for a while, noticed the top buttons depicting the WiFi and data internet connectivity is no longer clickable on a global scale. Like say if I want to shut all of the access down except for the one app I am using due to poor data speed out in the boonies, leaving all bandwidth available for the single app, I used to be able to just click the mobile data button to off and they all go off, then click the one app I'm using to on. Have to click each app now

Does exactly what I want. Had issues keeping it engaged, but found another app with vpn settings was competing. Set this one in phone settings as always on and mandatory so if it drops everything is blocked. Fixed my issues. I leave notifications off. I don't want nags on apps when they start. I know to go enable something if I'm not already always allowing it. The list is small and my memory is good enough.
