Changelog

Track what's new, improved, and fixed in Echoes.

v3.0.1

Sounding Redesign & Fixes

  • Skew-T soundings have a new design
  • On a phone, the sounding fills the screen with a vertical layout: Skew-T on top, hodograph and key parameters below
  • Rotate to landscape for the full composite with parameter tables and vertical profiles
  • Alert outlines could turn solid black instead of the event color, most often when the radar finished loading after the alerts; outlines now keep their colors
  • Animations could fall behind the live radar; an animation now loads the newest available frames and keeps picking up new frames while it plays
  • River gauges and air quality sites now refresh when you switch radar sites with the coverage mask on (before this fix, they kept the previous site’s coverage)
  • Land Surface Temp no longer shows cold speckle from thin cloud; its color range is now retuned to match
  • LIVE Sweep now handles an uncommon scan pattern that could stop a sweep from loading
v3.0.0

LIVE Sweep

  • LIVE Sweep (Premium): Echoes streams each ray the moment the radar collects it
  • The beam sweeps around and paints the storm arc by arc, at the radar’s real rotation rate
  • Works on any Level 2 product and any tilt
  • Real countdowns: the bottom bar counts down to the next radar frame second by second
  • In LIVE, the countdown follows the radar’s own scan schedule
  • Premium now follows your Apple ID, so one subscription works on all your devices at once
  • Premium settings survive a brief hiccup in subscription status instead of switching layers off
  • Alert polygons, mesoscale discussions, and the location marker now have outlines so they stay readable over bright radar returns
v2.1.0

Air Quality Forecast

  • Air Quality Forecast: tap any AirNow site to see the EPA AQI outlook up to six days out
