Ten fast, no-nonsense tools: • SubnetCalc — IPv4 subnetting: network, broadcast, wildcard, host range and binary • Network scan — detect active hosts or TCP ports, with CSV export • Continuous ping — real-time latency, jitter and packet loss • Speed test — latency, download and upload, with a Live Activity • HTTP probe — status, timing, headers, redirects and TLS certificate • WHOIS — registrar, owner, expiry and nameservers via RDAP • NAT detector — router NAT type and VoIP/SIP compatibility • SIP probe — reachability and capabilities of a PBX • Local network info — IP, gateway, DNS, MTU and connectivity test • DNS lookup — A, AAAA, MX, TXT, NS and PTR records over DNS-over-HTTPS Plus: Home Screen widget, speed-test Live Activity, Siri and Shortcuts. Available in 5 languages.

IT電卓+ is a focused calculator for engineers, network administrators, and learners studying for IT certifications. Four common tasks are organized into simple, switchable tabs. [Unit Conversion] Convert between bit, B, KB, MB, GB, TB, and PB. Toggle between SI prefixes (base 1000) and IEC prefixes (base 1024 — KiB, MiB, etc.) so you can match the convention you need for storage, memory, or traffic. [Subnet Mask Calculator] Enter an IPv4 address and a CIDR value to get the network address, broadcast address, first and last usable host, subnet mask, wildcard mask, and host counts. /31 (RFC 3021) and /32 are handled correctly as special cases. [Base Conversion and Bit Operations] Convert between binary, octal, decimal, and hexadecimal. Binary output is grouped every four bits for readability. AND, OR, XOR, left shift, and right shift are available on the same screen. [Link Speed and Transfer Time] Convert across bps, Kbps, Mbps, Gbps, B/s, KB/s, MB/s, and GB/s. Combine a file size with a link rate to estimate how long a transfer will take. [Languages] Japanese and English. [Privacy] Calculations stay on your device. The app does not upload your inputs or results.
