F3Analyzer - Share Link Tester app analytics for October 8

F3Analyzer hands a Shadowsocks, Trojan, VLESS or VMess share link to our service, which dials that server from its testing location. At no point does your phone reach the server under test. You get evidence, not a promise: a verdict, plus whichever of latency, download, upload and exit address could be measured. How a test works Bring a link in by pasting it, scanning its QR code with the camera, picking a photo of that code, or opening a text file. Your phone decodes and checks it first: a link with no server address, a private or reserved IP address written into it, or a transport the service can't dial is refused there, and no test is spent. Before the first test the app asks, and says our service receives the link as pasted, with the password or key the server needs. A test takes up to about a minute, and canceling spends nothing. What comes back Working: the server answered, and download, upload and the exit address were all measured. Partially working: the server answered, but one or more of those measurements is missing. Unreachable: the server name didn't resolve, or the server didn't answer or refused the connection. Not testable: the link can't be dialed as written, or its format isn't one the service dials. Badges such as Exit flagged add context but never change the verdict. Latency is the median of up to 5 HTTP round-trips via the server; upload is marked approximate. Figures are measured from the testing location, not from your phone. Reports other than Not testable give the test's duration and that location when known. Where available, the exit profile shows the exit address with its location, network, flags and a 0–100 risk score from an outside reputation service, banded Low, Elevated or High. The score reflects the address type and attacks seen from it, not the server itself. A tested report also shows the decoded configuration, with passwords and keys hidden until you reveal them, and a security audit run on your phone: 12 checks on the link's parameters, such as certificate verification turned off or a weak Shadowsocks cipher, with findings graded Critical, High, Medium or Minor. The audit reads how a link is set up, not who runs the server. Your library Tested links stay in a library on your phone with their latest result. Search, sort by last tested, latency, download or exit country, filter by verdict, mark favorites and re-test with a swipe. Turning off Auto-save results deletes stored results, and later reports are shown but not kept. My connection After a one-time prompt, this tab shows how your connection looks from outside: your public address (masked until you reveal it), location, network and risk score, which DNS server answers for you, and whether its answers for 8 well-known names agree with an encrypted resolver. Nothing from this tab is stored in the app. Free, and Full Report Free, with ads: 5 tests per day, reset at midnight. A test counts only when the service dialed the server; a refused link, a name that didn't resolve, a canceled test or a busy service costs nothing. The free tier holds 20 servers and 5 favorites, shows each audit finding's severity and title, and lets Batch decode a pasted list and test one link from it. Full Report, a one-time in-app purchase, adds: The explanation and fix for every audit finding. No daily test limit, and no library or favorite caps. Tests still run one at a time. Batch runs of up to 50 pasted links. Compare: two tested servers from your library side by side. Export: chosen library entries as a JSON or plain-text file, with passwords and keys masked unless you include them. No ads. Restore purchase is always in Settings. What it doesn't do F3Analyzer does not connect you to the servers it tests: it creates no tunnel, routes no traffic and installs no profile. There is nothing to sign in to and no analytics of its own. Beyond purchases and ads, only tests you run and the My connection tab use the network, and each asks the first time.
