What's New in 404 Network

1.12.1

October 27, 2026

Diagnostics that are easier to review and share • Export structured PDF reports with measurements, observations, test context and the limits of available results. • Organize site work with site dossiers and comparable measurements. • Pair devices with a guided flow and clearer connection details, including manually entered sensors. • Compare measurements between compatible devices and review available endpoint resource data. Missing data stays explicitly marked rather than being replaced with assumed results. • Improved layouts on iPhone Duo and at larger text sizes. • SSH now uses the background transition time allowed by iOS, without requesting location to stay active in the background. • Clearer privacy information explains private iCloud, optional community sharing and consented requests to your chosen cloud AI provider. Measurement availability depends on the platform, network and paired devices. Measured throughput alone is not a Wi-Fi radio measurement or proof of CPU throttling.

Response from developer

Thanks for being an early user, and for the kind words. The core scanning tools in 404 stay free. 404 Pro is a one-time purchase, not a subscription: you pay once and it stays unlocked on all your devices. Pro+ is an optional extra for the AI features. We can't give Pro automatically to early downloaders, but we really appreciate you sticking with the app since launch.

Surprisingly Amazing

The app works great on iOS and MacOS (the two platforms I tested) with only a couple of little GUI glitches on Mac (like on Mac, if I am using a specific tool, but then I navigate to another section of the app using the side menu, my interface doesn’t actually change to reflect what I v selected unless I manually click the “back arrow” in the top left corner…. OH and if I accidentally select a tool that required the Pro version of the app, there is no way for me to click out of it lol….i have force quit the app using the activity monitor app on Mac….trying to quit the app normally doesn’t even work 😂 but that’s normally an easy fix for the developer) and it’s super handy. Has a ton of tools as well. Might upgrade to pro soon. Also! This app does not ask you to upgrade! Sure some tools will require it, but it’s also not expensive or anything. So for simple troubleshooting, it’s great.
