App crashed/won’t open nor show in foreground but still running after going to Statistics after HIDS… turning it off/on as well as device shutdown didn’t fix it. iPhone 16 Pro up-to-date while Voice Over & Screen Curtain active. wanted to wait until next month, but since I’m here, was wondering if bootstrapping for destination DNS server addresses would be possible or in the works for the future, thanks and appreciate it and as always lightweight and the best app thus far and I have tested so many of them, cheers
[2026.08.11] Avg-Rating: 98.8. Great feature -had been in the back of my mind for months; I just turn off the proxy just to access those websites but this is very nice!

Didn‘t try out new features but Statistics finally working again, though a nightmare to navigate with Apple VoiceOver; having issues with external blocklist + mal/spy download but will continue testing.
[2026.02.15] Avg-Rating: 97.6. Have never rated an App this high before; surprised it doesn’t cost more for its simply designed eefectiveness… I am not always connected to any of my VPNs so this is a super easy setup when/where VPNs not necessary yet retaining DNS servers/profiles (HTTPS). Still having issues with the statistics and scroll boundary with iOS VoiceOver.
[2026.01.31] Avg-Rating: 97.2. Not fond of biometrics but cannot find the option and denying view access.
[2026.01.26] Avg-Rating: 97.2. v3.0 update is a tremendous improvement with many features, some I may not quite understand but explanations are supplied, thanks; and still lightweight as always.
[2026.01.15] Avg-Rating: 96.1 Fully blind user and after using for some time, this just is a great powerful tool..! Not sure if intentional design or not but one little annoyance is lack of go-back button in the view all blocked listing; I can use the screen gesture (but really dislike to unless necessary.)

Dear valued customer, I’m delighted you’re enjoying your journey with the app. Please stay tuned for many exciting new features coming soon! We take your constructive feedback very seriously and will work to improve the user experience as you’ve reported. [updated version 5.2] Dear valued customer, thanks for the suggestion about implementing bootstrapping for the destination DNS server. Could you describe what you're running into? For example: the upstream fails to connect on some networks, you want the hostname lookup not to use your local DNS, or you want to specify the upstream's IP manually? A concrete example of your setup would help me design it properly. Moreover I would love to know more about the crash you described in your comment as our duty is to continuously improve our app . Please let’s continue this conversation using our support email ADFastDNS@libero.it

Dear valued customer, I’m delighted you’re enjoying your journey with the app. Please stay tuned for many exciting new features coming soon! We take your constructive feedback very seriously and will work to improve the user experience as you’ve reported.

Fantastic

I was looking for something that would block direct IP connections to any IP address that didn’t result from a valid DNS response. This app does exactly that.

The anti-DPI and TLS Client Hello Fragmentation also totally bypass video throttling on both of my carriers. HIDS works exactly as expected too.

My only complaints are as follows:

1. Statistics are pretty limited. I can see how many Direct IP blocks there have been, but I can’t see the IP addresses. The statistics reset whenever you restart the proxy, which is a bit inconvenient. It’d be nice if they could carry over across sessions.

2. DNS cache does carry over between sessions. If you enable Direct IP blocking, it’ll basically cut off all most internet activity until the TTL of prior DNS records expire. But you can manually clear the cache though so it’s not a big deal.

Anyway I love the app. It’s in a league of its own. I hope y’all will consider making a Mac app in the future. Also this a big ask but it’d be really cool if you could add a socks5 proxy server similar to PairVPN where devices connected to the phone hotspot are routed through the proxy and their traffic is filtered by the the anti-DPI and HIDS system.

Dear valuable customer, Thank you so much for your kind words and for taking the time to share your experience with us! We are thrilled to hear that the app is meeting your expectation, especially regarding the anti-DPI features and Direct IP blocking. Knowing that the app is "in a league of its own" for you means a lot to our team. We also want to thank you for your constructive feedback. We take user suggestions very seriously as we continuously work to improve the experience: • Statistics & Persistence: We hear you on the need for more detailed IP logging and session persistence. We are currently looking into ways to expose more statistics data without compromising performance and energy usage. Regarding your request for a Mac version, we have some great news! The app is already available on the Mac App Store for all Apple Silicon (M1/M2/M3) devices. You can download it today to enjoy the same level of protection on your computer.
