SubnetBuddy vs Socketta

SubnetBuddy is a fast, offline subnet calculator and network planning tool built for IT professionals, network engineers, students, and anyone studying for their CCNA, CompTIA Network+, or just needs to crunch CIDR notation on the fly. No internet required. No ads. No account needed. Just open the app and start calculating. SUBNET CALCULATOR • Enter any IP address and CIDR prefix (e.g. 192.168.1.0/24) • Instantly see network address, broadcast address, first and last usable host • View total hosts, usable hosts, and wildcard mask • Get the next sequential subnet with one tap • Supports all prefix lengths from /0 to /32 MASK CONVERTER • Convert between CIDR notation, dotted decimal, and binary • Enter a prefix length and see all three formats instantly • Quick-reference for common subnet masks • Perfect for exam prep and on-the-job lookups VLAN PLANNER • Plan multiple VLANs with custom names and sizes • Set a base network and SubnetBuddy calculates non-overlapping subnets for each VLAN • See network range, gateway, CIDR, and host count per VLAN • Great for designing office networks, lab environments, and homework assignments IP VISUALIZER • Enter a CIDR block and see a visual map of the IP address space • Color-coded grid shows used vs. available addresses • Instantly understand how big (or small) your subnet really is • Tap any cell to see the full IP address TERMINAL-STYLE DESIGN • Dark theme with VibeCMD's signature hacker-green aesthetic • Monospace fonts and command-line inspired interface • Clean, distraction-free layout built for speed • Easy on the eyes during late-night study sessions WORKS COMPLETELY OFFLINE • Zero network calls — all calculations happen on-device • No account required — open and use immediately • No data collection — your network plans stay on your phone • Lightning fast — results appear as you type BUILT FOR REAL PEOPLE • IT professionals doing quick subnet math on-site • Students studying for CCNA, Network+, or any networking exam • Homelab enthusiasts planning their network segments • DevOps engineers carving up VPC address spaces • Anyone who's tired of Googling "what is /22 in dotted decimal" SubnetBuddy is a utility tool for network address calculations. It does not connect to or scan any networks.

One app instead of a dozen. Socketta is a professional network bench for iPhone and iPad: Wi-Fi speed test, LAN scanner, port scanner, ping, HTTP/REST client, WebSocket, MQTT, BLE tools, traceroute and on-device network diagnosis — 25+ tools in a single, focused instrument. WHY SOCKETTA • Replaces a stack of single-purpose apps (network scanner + API tester + MQTT client + BLE scanner + speed test) • No ads. No account. No data collection — everything runs on your device • Fair pricing: a genuinely useful free tier, subscriptions, and a one-time lifetime purchase (no forced subscription) MEASURE • Wi-Fi speed test with an instrument-grade analog gauge (download / upload / latency / jitter / packet loss) • Ping (TCP, custom port), batch ping, traceroute with per-hop latency • Network quality score for gaming, VoIP, video calls and streaming • On-device diagnosis engine: find out why the connection is slow — no cloud, nothing leaves your phone SCAN • LAN device scanner: see every device on your network with vendor and type • Port scanner (parallel), DNS & reverse DNS, mDNS browser • Wake-on-LAN, UPnP/SSDP browser, network topology map, scan diff (spot new devices) • SSL certificate viewer, WHOIS lookup, HTTP header analysis, subnet calculator DEVELOPER BENCH • Full HTTP/REST client: methods, headers, auth, cURL import/export, Postman import, code generation (Swift, Python, JavaScript, Kotlin, PHP, cURL) • WebSocket client, MQTT client, UDP/TCP send & listen, millisecond precision send engine • BLE central & peripheral: scan, connect, read/write/notify, beacons, RSSI radar • Cross-protocol macros, profiles, scheduled tasks, JSON/CSV/TXT export HONEST NOTES • iOS does not expose MAC addresses of other devices to any app; Socketta identifies devices by vendor, hostname and mDNS data instead. • Local-network features require the Local Network permission. FREE & PRO The free tier includes unlimited ping, speed test, Wi-Fi info, LAN scan, DNS, Wake-on-LAN and lightweight utilities, plus trial uses of the advanced tools and a daily message allowance. Socketta Pro unlocks everything with a weekly, monthly or annual subscription (7-day free trial on annual) — or a single lifetime purchase with no subscription at all.
