LAN scanner: - Fast and reliable detection of all network devices - IP addresses of all discovered devices - MAC addresses and vendor names of discovered devices - NetBIOS, mDNS (Bonjour), LLMNR, DNS, SNMP, and WS-Discovery name where available - Reachability (ping) test of discovered devices - IPv6 availability and discovered IPv6 addresses Ping & traceroute: - Round-trip delay including IP address and hostname for every network node - Country detection of the analyzed server - Support for both IPv4 and IPv6 Port scanner: - Scan common ports, custom port ranges, or the complete port range - Detection of closed, firewalled, and open ports - Description of the known open port services Whois: - Look up domains, IP addresses, and AS numbers - Support for both classic whois and the modern RDAP protocol DNS lookup: - Functionality similar to nslookup or dig - Query all record types at once or one specific type - Support for A, AAAA, CAA, CNAME, HINFO, LOC, MX, NAPTR, NS, PTR, SOA, SPF, SRV, SSHFP, TXT records Network information: - Default gateway, external IP (v4 and v6), DNS server, HTTP proxy - Wi-Fi network information such as SSID, BSSID, router vendor, security type, IP address (v4 and v6), and subnet mask - VPN, USB Ethernet, and personal hotspot connection details - Cell network information such as IP address and network type, with dual SIM support More: - Light and dark theme - Full IPv6 support everywhere - Detailed help - Regular updates

SSL Certificate Checker helps you monitor SSL/TLS certificate health for the websites and services you care about. Add one or more targets (hostname + port, default 443), run a check instantly, or scan your whole list in one tap. The app is designed for a quick daily workflow: open, scan, review risk, and act. What you can check: - Expiry date and days left - Status classification: OK, Expiring, Expired, Failed - Issuer and subject - SAN (Subject Alternative Name) - Serial number and signature details - SHA-256 certificate fingerprint - SHA-256 public key fingerprint - Negotiated TLS protocol and cipher suite Key workflows: - Single target check for immediate troubleshooting - Full list scan for regular maintenance - Saved targets and latest results stored locally on device - Optional periodic background checks (can be turned on/off) Built for practical certificate operations: - Quickly identify certificates close to expiration - Compare protocol/cipher negotiation outcomes - Keep a simple watchlist for internal or public endpoints - Generate and review report-style outputs inside the app Security perspective for connected-device teams: - Includes TLS protocol and cipher suite visibility to support baseline security reviews - Helps teams spot weak or unexpected negotiated ciphers during routine checks - Useful as an evidence aid for internal security discussions and release readiness - Designed as a practical checker, not a complete legal/compliance assessment tool Regulatory context note: - In the EU, RED cybersecurity delegated requirements under Directive 2014/53/EU Article 3(3)(d)(e)(f) apply from August 1, 2025 for covered products - This app can support early HTTPS/TLS posture checks, but it does not certify compliance with RED-DA, EN 18031, or any other regulation/standard on its own Privacy and control: - No account is required to start checking - Targets and recent check results are kept locally for your routine usage - Privacy policy and terms are available from within the app Current release focus: - Core SSL/TLS checking flow and result parsing are available - Batch checking and retry flow are available - iOS background checks are best-effort (system-scheduled) - Multilingual UI foundation is integrated; some languages are still being refined This app is suitable for developers, operators, site owners, and anyone who wants a simple way to track certificate validity and TLS configuration from a mobile device.
