Radar opens with one map and a timeline. Its short menu separates Radar, Overlays, Alerts, and Tools. The fixed header keeps Radar, Analyst, search, and Settings within reach even when the menu is closed.
Analyst adds linked panes, presets, an active-pane label, and an optional inspector. Choose Radar again to restore the single map you left; return to Analyst to resume its arrangement. Save a workspace to keep it across restarts.

The Clearview desktop layout uses a compact Context bar for Radar, Layers, Alerts, Tools, Search and Settings. Focused menus open below it; All controls retains the full catalog and advanced options. Priority dock and playback share a 330-point width in the bottom-right corner, keeping the radar center clear. It shows the most relevant nearby bulletin, with the full alert list, storm tracks, and display rules one click away. Graphite Silver is the default; choose Midnight Blue, Deep Pine, Smoked Plum, or Warm Ember in Settings → Appearance. Advanced radar tools remain in the Layers panel.
Priority display rules use separate advisory, watch, warning, and high-impact distance limits around your saved home (or selected radar site). Warnings containing that point remain visible through these thresholds. Track filters use actual SCIT forecast error and scan age, with a configurable 15–60 minute projection; they do not infer official warnings or change notification delivery. Settings → Alerts → On the radar exposes the same dock and track controls.
Settings opens with six home cards. Alerts uses three tabs: On the radar for map visibility and display rules, Notify me for sound, severity and quiet hours, and Delivery for phone, chat, radio and background options. Close and Done remain accessible above and below the scrolling page.

Everyday controls stay simple. The deeper weather tools remain available without crowding the main map.
For everyday use: open the map, see whether rain is coming, and read warnings without learning radar terms.
For outdoor plans: save home, work, events, or travel stops and watch the weather near each place.
For weather enthusiasts: compare radar products, split the screen, inspect storm structure, use forecast layers, and replay historic events. These tools stay tucked away until you ask for them.
HookEcho can warn you when official weather alerts approach a saved place. Depending on your device, alerts can appear in the app, browser, phone notification, email, Discord, Telegram, or another service you connect.
The app explains what the warning is, where it is, and when it expires. It can read warnings in the visible map area through the bundled Piper voice; emergency speech interrupts routine notices.
HookEcho has no user accounts, ads, or app tracking. Radar, forecasts, and warnings come from public weather services. Your saved places and preferences stay on your device unless you choose to connect a syncing or alert service.
Questions are welcome in GitHub Issues or on Discord.
