Constellation at Starlight provides off-grid messages and live location, together at last. Bring the app and you're a node: together we weave people into a locally-operated network, alive only inside the venue. No internet. No default world. Works in airplane mode — install before you arrive to stay connected despite network congestion. EVERY SOUL A STAR • See your friends on the live star chart of the event — every WYA ping, every art marker, every "walk me home" draws another line between stars • Step-by-step directions to a person or a point of interest • Share your pin, or go dark — you're always in control MESSAGE OFF GRID • Airplane mode, dead zone, dust storm: your words still find your people, phone to phone • The mesh is a living reflection of the community that raises it — every person on Constellation makes the network stronger • Private by nature: what's spoken on the mesh stays on the mesh A NETWORK BUILT OF PEOPLE • No SIM, no bars, no setup ritual — open Constellation and you're on • Each node reflects its person, each person connects the community • The crowd is the signal SOVEREIGN DATA • Nothing stored, nothing sold — your history lives and vanishes in your own two hands • No account, email, or phone number required — your identity stays on your device • Location sharing is opt-in per friend and requires manual check-in each session

HamTraqr puts every volunteer at a public-service event on one live map — hikers, bikes, sweeps, SAGs, aid stations, net control — and keeps them in touch. Built for the people who work races, parades, marathons, rides and emergency exercises: the operators who need to know where everyone is, who just called, and what was said, usually all at once. REQUIRES A SERVER HamTraqr is not a service we operate. Your club installs the free, open-source HamTraqr Server on its own hardware, and this app connects to it. You will need your club's server address before the app can do anything. There is no account to create and no sign-up. ON THE MAP • Live positions for APRS trackers and for phones running this app • Courses, aid stations and iGates, drawn from your event's configuration • Tracker names, callsigns and how long since each was last heard SHARE YOUR POSITION • Become a tracker with just your phone — no radio hardware required • Support for an APRS-capable radio if you have one • Reports continue with the screen off, with a notification shown the whole time • Turn it on for your shift and off afterwards; nothing is sent until you do MESSAGING • Message net control or other trackers directly, and receive event-wide broadcasts • Attach a photo when a description is not enough • Spoken alerts for incoming messages, so you can keep your eyes on the road • Option to hear the live radio transmissions on the event's primary frequency ON YOUR WRIST The Apple Watch companion is for when the phone is in a pocket and your hands are busy: incoming messages on the wrist, and a reply dictated by voice. YOUR DATA STAYS WITH YOUR CLUB Everything you share goes to the server you connected to and no further. We operate no service that receives it, and the app contains no analytics or advertising of any kind. Whoever runs your club's server holds that data and answers for it — their policy is published on the same address you enter into the app. Note that APRS is an open radio system. Positions transmitted over the air can be received by anyone in range and appear on public sites such as aprs.fi, independently of this app. LICENSING No amateur radio licencs is needed to use the app as a tracker; position sharing goes over the internet. A license is required to transmit on amateur frequencies, and your club will tell you which parts of an event need one. Free, with no in-app purchases.
