Zero Network Tools vs Coucou

Zero Network Tools Zero Network Tools turns your Apple Watch into a pocket-sized network administration toolkit for IPv4, IPv6, subnet planning, device setup, troubleshooting, and field work. Calculate IPv4 subnets from your wrist. Enter an IP address, choose a CIDR prefix, and instantly see the network address, subnet mask, usable host range, broadcast address, wildcard mask, host count, suggested gateway, and whether the address is usable, reserved, a network ID, or a broadcast address. Use the This Watch tool to detect your watch’s current Wi-Fi or LTE IPv4 address and calculate the subnet it is connected to. Quickly confirm the network, mask, broadcast address, usable range, and address role without reaching for a laptop. Plan networks with built-in admin tools: • VLSM subnet planner • DHCP scope planner • VLAN planning notes • Previous and next subnet navigation • Second-IP subnet membership checker • Saved subnet plans • Router, switch, static device, and change-ticket templates • Common port reference • Private, loopback, APIPA, multicast, and reserved range reference • IPv6 prefix calculator • DNS A/AAAA lookup • Binary and hexadecimal subnet math logs • TXT, CSV, Markdown, and JSON export sharing Zero Network Tools is useful for network admins, field technicians, homelab builders, IT students, cybersecurity learners, and anyone who works with routers, switches, VLANs, DHCP scopes, servers, printers, cameras, IoT devices, or static IP assignments. Cool things you can do: Check if an IP is safe to assign Find out if an address is a broadcast address Detect the subnet your watch is currently using Build DHCP scopes after reserved infrastructure addresses Plan VLANs and document gateway settings Generate device registration notes Compare binary and hexadecimal subnet math Look up common service ports like SSH, FTP, NFS, NNTP, DNS, DHCP, RDP, VPN, and more Resolve DNS records from your watch Export subnet records for tickets, documentation, or sharing Built for quick checks, real network work, and learning subnet math anywhere.

Coucou is the iPhone companion of Coucou for Mac, the little friend who lives in your MacBook's notch and keeps an eye on your AI coding agents: Claude Code, Cursor and the Claude desktop app. SEE YOUR SESSIONS Every agent session from your Mac, live: what it's doing, its plan step by step, its last message. The most urgent one first. Several sessions in the same project each get their own row, with their real title. ANSWER FROM ANYWHERE When an agent needs your permission, you get a notification with the exact command. Deny it right from the notification, or allow it with Face ID. When several sessions ask at once, each question and request gets its own card, and you answer them one by one. Your Mac only applies a decision meant for the exact request it is waiting on, and requests expire after 2 minutes. MOCHI IN YOUR DYNAMIC ISLAND Lock your Mac while an agent works: Mochi moves to your iPhone's Lock Screen and Dynamic Island, and comes back to the notch when you unlock. WIDGETS Solo, Team and List on the Home Screen, and Mochi on the Lock Screen, in the colours you picked for each Mochi on your Mac. PRIVATE BY DESIGN No account, no analytics, no ads. Your sessions travel through your own private iCloud, with project names, commands and questions encrypted with your iCloud keys. Requires Coucou for Mac with Settings → General → iPhone turned on, and the same Apple Account on both devices.
