About

RagChew

Features
Read full description

RagChew is a companion app for amateur radio operators who want to follow nets without being at their radio. It connects to NetLogger and shows you what's happening on active nets in real time. EchoLink (Still in Beta and may be buggy): RagChew now includes EchoLink support. You can listen to nets over EchoLink audio directly in the app and transmit using the built-in push-to-talk button. A live audio level bar and connection quality indicator keep you informed while you're connected. Node descriptions are available to help you identify links and repeaters. Notifications: RagChew can send you push notifications so you don't have to keep the app open to stay informed. You can receive alerts when a net you've favorited goes active, when a favorited station checks into any net, and for other activity you choose to follow. Notifications are configurable so you only hear about what's relevant to you. Check-ins: The full check-in roster is displayed as operators join, including callsign, name, and status. You can see who is currently operating, who is mobile, and who has checked out. Tapping a check-in expands additional details and provides a link to the operator's QRZ profile. Net chat: If you monitor a net, you can read and send messages in the net's chat. The full message history is available, and you can react to individual messages. NetLogger-style text formatting is supported. Map: Check-ins are plotted on a map based on their logged positions, giving you a geographic view of who is participating in the net. Favorites and monitors: You can favorite nets and individual callsigns to track activity that matters to you. You can also see which other operators are currently monitoring any given net. Net history: Recently closed nets are available to browse, including their full check-in rosters and session information. Groups: Nets can be browsed by club or group, with group descriptions and associated net listings. iPad and landscape layouts: On iPad, the net detail screen uses a split layout that displays net information, the station map, check-ins, and chat simultaneously. On iPhone, a landscape layout presents check-ins and chat side by side. Both portrait and landscape orientations are supported on all devices. Account: Sign in with your existing NetLogger credentials. No separate account is required. Favorites, monitors, and chat require a login; active net listings and basic check-in information are available without one. The app supports light, dark, and automatic appearance modes and is available on iPhone and iPad.
