About hookecho

Advanced NEXRAD weather radar viewer — an open-source homage to supercell-wx, built from scratch in Rust with wgpu + egui. Deep per-site Level 2 / Level 3 analysis plus national situational awareness, forecast environment overlays, and warning intelligence — on Windows, Linux, and Android.

What's new in 0.12.0-beta.2

Second R18 checkpoint. The phone gets the same chrome the desktop got in
alpha.1, onboarding stops asking questions, and the data lanes land. Still a
prerelease: a few lanes (RRFS, the remaining store submissions) come at 0.12.0.
The phone
- The persistent bottom sheet and the five-slot toolbar are gone. The phone
draws the same floating chrome the desktop does — search pill, control
column, scrubber — with content in Material modal sheets instead of a
drawer. Predictive back still works.
- Long-press the map to inspect what is under your finger, double-tap and drag
to zoom with one hand, swipe sideways between panes.
- Haptics: ticks as the scrubber crosses a frame, a buzz when a warning lands
on you, a bump when a sheet snaps.
- Tablets and landscape phones get a side rail and a docked drawer instead of
sheets.
- Widgets show how far the nearest storm is. A battery-saver mode stretches
the poll cadence and throttles repaints. On a chase, the next radar down the
road is prefetched before you need it, and a chase can be replayed against
the archive afterwards.

Getting started
- The setup wizard is gone. First run finds you, picks the nearest radar and
draws it — about ten seconds, no questions.
- Notification permission is asked for when you turn on something that
notifies, or when a warning lands near you. Never at install.
- One help hub behind ?: glossary, hotkeys, the tour and what's new, all
searchable in one place. Labels across the app read in plain language, with
the abbreviation kept in parentheses for anyone who wants it.
- Text products — area forecast discussions, tropical advisories — render in a
real webview with real typography, on both desktop and Android.

Weather
- GOES loops run over archive dates alongside the radar timeline, and the
mid-level water vapor bands are selectable.
- MRMS rotation tracks (30/60/120 minutes) are field layers now, and hail
swaths accumulate locally over a window you choose.
- Snow squalls and banding get their own emphasis in winter.
- An alert rule can trigger on a lightning jump — the rate of change of flash
density inside a cell.
- NAM nest and NBM join the model list. Synoptic mesonets join the surface
obs, with your own API key.
- Cells are ranked by a composite severity score, and tapping one opens the 3D
volume already centered on it.
- Panes remember their own thresholds and field layers. Events can be saved as …
