Cert Recon vs Pingly

Cert Recon reads the TLS certificate chain a server presents and explains it in plain language: who issued it, when it expires, which names it covers, and whether this device trusts it. It also answers a question most computers cannot. Your phone holds two independent paths to the internet at once. Cert Recon asks the same host over Wi-Fi and over cellular and compares the answers, because a network that intercepts TLS has to re-sign the connection with its own certificate authority. The cellular path shows you what the certificate should have been. Hotel, airport, conference and corporate guest networks do this routinely. On a device with one path, it still catches the common case: a certificate that this device trusts yet carries no Certificate Transparency timestamps is being vouched for by an authority installed on the device rather than a public one. That is how a filtering proxy works, and Cert Recon names the authority doing it. WHAT YOU GET • The full chain, leaf to root, exactly as the server presented it • Every field: subject, issuer, validity, key type and size, signature algorithm, serial, SANs with their types, key usage, extended key usage, basic constraints, certificate policies, OCSP and CRL URLs, CT timestamps • SHA-256, SHA-1 and public-key (SPKI) fingerprints • Trust evaluated against this device's store, with the reason it failed rather than a red cross • Expiry countdown, weak-key and weak-signature flags, hostname mismatch and self-signed detection • Interception check: Wi-Fi against cellular, issuer sanity, transparency timestamps, captive-portal awareness • Pin a host's key and be told if it changes • History of what you have inspected, one tap to run again • Export the chain as PEM or the finding as a text report • Configurable port and SNI • iPhone and iPad, dark-first PRIVACY Nothing leaves your device. No account, no analytics, no tracking, no third-party frameworks. Hostnames you inspect are not transmitted anywhere. Pinned hosts and history stay on the device. Cert Recon is a certificate inspector: it completes the TLS handshake, reads the certificate, and closes. It sends no request body and no HTTP to the host you name. FREE No in-app purchases, no subscription, no gated features. Part of the 404 Tools Recon suite; hand any host straight to the other Recon apps you have installed.

Pingly is a small, fast network tool for people who want to know what their connection is actually doing. Type in a host or IP, watch the ICMP replies come back in real time, and keep a running score on your Internet quality. If you chase latency for work, hunt down lag before a match, or just have a Wi-Fi connection you don't trust, Pingly gives you the real numbers as they happen. PING ANY HOST • Real ICMP echo requests, the same kind the ping command sends • A live reply stream with sequence number, packet size and round-trip time • Running stats: sent, received, lost, loss %, min, avg, max and jitter • Quick-pick hosts, and switching targets starts a fresh session • Color-coded latency, so a slow reply is easy to spot INTERNET QUALITY MONITOR • A running 0-100 connection score with a letter grade from A+ to F • A live breakdown of latency, jitter, packet loss and stability • A scrolling signal graph and a one-line, plain-English read on how things look • Pause, resume, or switch targets whenever you want SONAR · AUDIBLE PING • A tone for every reply, pitched by round-trip time - fast replies ring high, slow ones drop low • A healthy connection sounds like a steady, high chime, so a latency spike is a note you can hear fall • Timeouts and dropped packets get their own distinct downward thud • A live tone-bar strip that scrolls along with the stream • Four voices to choose from sine, triangle, square or pluck • Leave it running with the screen off; it respects the mute switch SESSION HISTORY • Every ping run is saved automatically • A latency chart and full stats for each one • Save the hosts you use most for one-tap pinging • Recent sessions with small sparklines so you can scan them fast SETTINGS • Set the ping interval, packet size and timeout • System, Light or Dark appearance • Monospaced, tabular numbers that hold steady as they update PRIVACY • No account, no ads • Nothing leaves your phone. Pingly only pings the hosts you point it at. That's the whole app. It just tells you how your connection is doing.
