What's New in ADFastDNS

4.5.3

July 9, 2026

A few exciting new features: - Who said that a complex security tool like ADFastDNS requires an expert user? Choose your protection level in one tap: Minimum, Medium, or Max right from the Home screen. Minimum enables DNS filtering with curated blocklists. Medium adds Anti-DPI to defeat deep packet inspection. Max adds full on-device intrusion detection (HIDS) for JA4 fingerprinting and threat scoring. No manual configuration required. Prefer full control? Every individual setting is still there for advanced users in the DNS/AD Blocking, Anti DPI, and HIDS tabs. - Adaptive traffic shaping. ADFastDNS now learns and mimics the natural timing patterns of each connection, making proxy traffic statistically harder to detect and throttle. Fully on-device, private by design. No toggle to enable, it is enabled by default. - We have fixed an issue in the TCP/IP state machine that could corrupt packet's retransmission - We have fixed an issue in the stateless TCP/IP 3WH that could have caused the first packet to be lost causing the connection to be corrupted - We have fixed an issue that may required a manual restart of ADFastDNS after reboot as the network could be unreachable. - We have made significant optimisation for performance and energy efficiency.

Nothing but Perfect & Outstanding

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.

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.
