Socketta: Ping & SSL Checker

See who's on your Wi‑Fi, check your network's security and keep a speed history — plus a full network bench. Everything is worked out on your device. No ads, no account, no tracking.

WHO'S ON YOUR WI‑FI
• Finds the devices on your network and names them from what they announce (Bonjour, UPnP, NetBIOS, web pages) and from your router's DNS: name, maker, model and type. A device that announces nothing is shown by its address
• Changes since the last scan: devices that appeared and devices no longer seen

SECURITY CHECK
• A read-only check of your router and devices: reachable remote-login, file-sharing, screen-sharing and camera services, ports forwarded from the internet (UPnP), an admin page without HTTPS, DNS that answers for names that don't exist, and certificate validation
• A score and grade, what each finding means, and what was and wasn't checked. It checks network settings — it is not a virus scan, and it never logs in or changes anything

MEASURE
• Speed test (Cloudflare): download, upload, latency, jitter and loss, kept with your provider's name, looked up on your device
• TCP ping to any host and port (not ICMP), batch ping, a path check showing the destination's network operator, quality score and network diagnosis

SCAN & DEVELOPER BENCH
• LAN scanner (every host that answers a TCP probe), topology map, port scanner, DNS lookup, mDNS and UPnP browsers, scan diff, SSL viewer, WHOIS, HTTP headers, subnet calculator
• HTTP/REST client with cURL/Postman import and code generation, WebSocket, MQTT, UDP/TCP, precision send, BLE central & peripheral, macros, profiles, schedules (while Socketta is open), export

HONEST NOTES
• iOS doesn't let apps read MAC addresses; devices are recognized by name, UPnP identity or address. Devices that answer nothing (phones asleep, firewalled PCs) can be missed
• Socketta doesn't have Apple's multicast permission, so the UPnP browser asks each address directly and Wake-on-LAN sends to the device's IP address; some devices can't be found or woken this way
• Ping is TCP: a closed port counts as loss. Local-network features need the Local Network permission. The speed test and the certificate check contact Cloudflare, and the DNS check asks your network's own DNS about two made-up names; nothing is sent to us

FREE & PRO
Free: unlimited device identification, changes since the last scan, 20 remembered devices on one network, the security score with every finding explained, speed test with the last 10 results, and the scanning and network tools; advanced tools have trial uses and a daily send allowance.
Pro adds: alerts when a device never seen on that network before joins (while Socketta is open, or from the "Check This Network" Shortcuts action), a trusted list, device names and history, unlimited devices on every network, the device, port and step-by-step fix for each finding, re-check history and a report, the full speed history with a time-of-day chart and CSV export, and the advanced tools without limits.
Weekly, monthly or annual subscription (free trial for new subscribers: 7 days on annual, 3 days on monthly and weekly) or a one-time lifetime purchase, charged to your Apple ID.
