F3Analyzer Full Report
Audit fixes, no caps, batch, compare, export
F3Analyzer sends your share link to a remote service that dials the server from its location. This provides evidence of latency, download/upload speeds, and the exit IP address without your phone directly connecting to the server.
Results include 'Working' (all metrics measured), 'Partially working' (some metrics missing), 'Unreachable' (server not found or refused), or 'Not testable' (link format invalid). Badges add context but do not change the main verdict.
Yes, F3Analyzer runs a security audit on your phone, checking 12 parameters of the link's configuration for issues like disabled certificate verification or weak ciphers. Findings are graded Critical, High, Medium, or Minor.
Tested links and their latest results are saved in a library on your phone. You can search, sort, filter, mark favorites, and re-test links. Auto-save can be turned off to prevent storing results.
This tab shows your public IP address, location, network, risk score, DNS server, and whether its answers for common names align with an encrypted resolver. None of this data is stored by the app.
Yes, F3Analyzer contains advertisements. The free version allows for 5 tests per day, resetting at midnight.
F3Analyzer is free to download and use, supported by ads. It offers in-app purchases, likely for removing ads or unlocking additional features or tests.
