NodeScope vs CairnOS

NodeScope is an unofficial, read-only companion for CoreScope and Beacon, the mesh network analyzers used by MeshTexas and other MeshCore communities. It connects directly to a selected analyzer’s public API to present nodes, packets, channels, routes, observers, and analytics on iPhone and iPad, with adaptive layouts for iPhone Duo. Beacon support is in beta. Available features and history may vary by server. EXPLORE YOUR NETWORK View active nodes, online observers, recent packets, and signal information. Search across nodes, observers, channels, public keys, and packets, then save favorites for quick access. NODE ANALYTICS Evaluate nodes across multiple time ranges using native charts and summaries. Depending on the analyzer, NodeScope can display availability, signal quality, packet or observation activity, relay behavior, observer coverage, packet types, hop counts, peer interactions, and neighboring nodes. Beacon observation history is limited to the history retained by the server, currently up to seven days. Unavailable metrics are clearly identified rather than estimated. Export supported analytics as CSV or JSON. LIVE MESH MAP See known nodes on the map, distinguished by role. Live packet traffic animates hop-by-hop across the mesh. Filter by region, node role, activity, or observer. Inspect confirmed route hops, observations, packet metadata, and public text content. Replay supported routes on the map or share route details as structured text. Adaptive layouts can show the map alongside the live packet feed on supported devices. LIVE PACKETS Follow mesh traffic as it arrives. NodeScope groups observations of the same transmission so you can distinguish unique packets from the observers that received them. Filter the feed, inspect packet details, replay supported routes, or pause while exploring and return with Resume Live. CHANNELS Browse available group-channel traffic as a conversation feed and load older messages retained by the analyzer. CoreScope supports public channel history and locally monitored key-protected channels. Keys are stored in your device’s Keychain and are never sent to the analyzer. Beacon can provide server-decrypted channels whose keys are known by that server. On-device monitored-channel decryption is not currently available for Beacon. OBSERVERS Inspect devices feeding the analyzer, including available hardware information, firmware, activity, packet or observation statistics, and signal measurements. Supported Beacon servers can also provide battery voltage, noise floor, airtime, uptime, and receive errors. Missing measurements are shown as unavailable rather than zero. SEARCH, FAVORITES, SHARING, AND EXPORTS Search the network and save important channels, nodes, and observers to your Explore dashboard. Customize dashboard statistics, export supported data, and share direct links to nodes, observers, channels, and packets. Add supported nodes to MeshCore with a contact QR code, or open, copy, and share their MeshCore contact links. DIAGNOSTICS AND STORAGE Check analyzer connectivity, compatibility, live-update status, and available capabilities. Review cache usage and safely clear downloaded data without removing favorites, channel keys, or preferences. COMMUNITY ANALYZERS Choose from supported community CoreScope and Beacon sources, or enter a compatible analyzer hostname. Beacon sources are marked as beta. NodeScope has no backend of its own. It connects directly from your device to the selected analyzer. No NodeScope account or sign-in is required. PRIVACY BY DESIGN NodeScope contains no advertising, tracking, or third-party analytics SDKs. Location access is used only to show your position and center the map. Your location and locally stored channel keys are never transmitted by NodeScope. NodeScope is an independent project and is not affiliated with CoreScope, Beacon, MeshTexas, or MeshCore.

Cairn is a companion app for MeshCore LoRa mesh radios. Pair your radio over Bluetooth or WiFi and send messages through a community-built network of radios and repeaters, with no cell service, no internet and no account. MESSAGING - Direct messages, channels and room servers in one inbox, with filters - Public, private and hashtag channels; share or join a channel by QR code - Delivery status, with retry for failed sends - Emoji reactions, @mentions, forwarding, search and text selection - Path details for each message: every hop on a list and a map - On-device translation of incoming messages - Chats kept on a Cairn touch radio come over to the app when you pair - Block contacts or channel senders, filter keywords and mute conversations - Optional link previews, with a warning for known malware links DASHBOARD - Battery, network, radio, GPS, contacts and chats at a glance - Sunrise and sunset for your position and the radio's temperature sensor - Radio presets by region, or set frequency, bandwidth, spreading factor, coding rate and TX power yourself NODES & REPEATERS - Saved and heard nodes, with search, sort, filters and a card or list layout - A page for every node, with a map, readings and quick actions - Log in to your repeaters and room servers to see status, telemetry, neighbors and an SNR map, then change settings, access lists and regions or use the remote CLI - Send commands to your own companion radios over the mesh (MeshCore 1.18 firmware) - Telemetry history charts kept on your phone - Contact groups, QR sharing and a manual path editor SPECTRUM - Live noise floor and packet traffic on your frequency - Signal margin, airtime share and packets per minute - With a Cairn radio: the radio's own Channel view, with its trace, density heat map and 24-hour noise floor MAPS & GPS - Mesh map with standard, satellite and topographic layers - Live traffic layer: the links packets crossed lately, and each new packet as it arrives - Download map regions for offline use - Radio and phone GPS side by side, with a compass and a navigation HUD that points the way to any node TOOLS - Network Health, Scan for Nodes, Trace Path, Line of Sight with terrain and Fresnel zone, RX Log and a CLI terminal - Sign and verify messages with your radio's identity IN THE CAR & AROUND iOS - CarPlay: a dashboard of your radio, mesh, messages and location, a GPS page, and messages you hear and answer with Siri - Siri and Shortcuts: check radio status, send a message or send an advert - Live Activity and Dynamic Island with connection, battery and unread count - Multiple windows on iPad MAKE IT YOURS - Choose a color, gradient or photo background with glass cards over it - Give any node a photo or a color: its type's color, one of twelve shades or any color you pick - Backup and restore, plus CSV and GPX export PRIVACY Your messages travel radio to radio. Cairn has no accounts, no analytics and no developer server. Nothing is sent to the developer. REQUIREMENTS Requires a LoRa radio running MeshCore companion firmware, connected over Bluetooth or WiFi. Maps, link previews and Line of Sight elevation use the internet when it is available. Requires iOS 18 or later. Cairn is free and open source software under the GNU GPL v3, built on the work of the open-source MeshCore app community. Source code is linked from our support page.
