Pulse: Network Toolbox

Pulse is a network toolbox for iPhone and iPad, built for the people who get asked why the network is slow. It measures a network and tells you what the numbers mean — and opens a terminal on the machine at the other end. PULSE — CONTINUOUS PATH MONITORING Re-walks the path to a host every few seconds and keeps a window per hop, so a router losing one packet in twenty becomes visible. It tells a hop dropping your traffic from one merely rate-limiting its own replies; most tools paint both red. When a host has both, choose IPv4 or IPv6, or watch the two side by side. HEALTH CHECK Eight checks and a plain verdict in about ten seconds — the link, this device's address, the router, the neighbours, DNS, the internet, your public address, any VPN — naming the earliest failure, the one that explains the others. SERVICES Sixteen everyday services — video calls, files, sign-in and mail, remote desktop — checked against their real endpoints in about fifteen seconds, with a plain verdict and one tap to a Pulse on the worst one. DEVICES Everything else on this network: named by what each device advertises, with an opt-in check for open ports on the ones you pick. ON THE LOCK SCREEN AND HOME SCREEN A running Pulse is a Live Activity on the Lock Screen, in the Dynamic Island and on your Apple Watch, and it alerts you when the path turns bad. A widget answers "is this network OK right now?" from Pulse's last check, with how long ago, refreshed in the background. AI DIAGNOSIS A reading of any run, written for a ticket: what is wrong, where, why, and what to try next, with the evidence it used. You are asked before anything is sent, and told exactly what goes. TERMINAL SSH and telnet for the hosts the other tools point at, with passwords and keys in this device's Keychain and a key row above the keyboard. Open one straight from a traceroute hop or a device on your network. Every command you ran, per host, searchable, with anything irreversible marked. And SFTP over the same connection, in two panes. AND THE REST Certificate checks, with whether the server sent its intermediates. Ping with RFC 3550 jitter. Traceroute over ICMP, UDP or TCP. Path MTU. DNS with every record type. WHOIS over RDAP or port 43. Interfaces, routes, VPN and proxy state. EVERY RUN IS KEPT And judged again, against today's thresholds, each time you open it. Pin any tool to one interface to measure Wi-Fi and cellular separately. PULSE PRO Every measuring tool is free, and so are the terminal, the Live Activity, the widget and seven days of history. Pro adds the AI diagnosis, each service's endpoints and your organisation's own, device names that stick and what is new on your network, a link test between your own devices, two interfaces or IPv4 and IPv6 side by side, up to six Pulses at once, session comparison, picture and CSV export, full history synced through your own iCloud, sessions that stay open, command history and suggestions, file transfer, and a terminal on any hop or neighbour. Pulse Pro is an auto-renewing subscription, monthly or yearly. Payment is charged to your Apple Account at confirmation of purchase and renews unless cancelled at least 24 hours before the period ends. Manage it in Settings. Privacy: https://peltriaux.com/pulse/privacy Terms: https://peltriaux.com/pulse/terms PRIVACY No accounts, no analytics, no advertising, no trackers. Your runs stay on this device, and sync through your own iCloud — which the developer cannot read — only if you turn that on. A terminal session runs between you and the host you named: keys and passwords stay in the Keychain, and nothing you type there reaches the developer or an AI diagnosis. Only the AI diagnosis sends anything to a service the developer runs, and only when you ask.
