Display Fronts and radar
With the wonderful “Storm” application gone and replaced by the woefully inadequate “Strom Radar,” i look for a suitable replacement. You have the best isobars combined with wind display, period.
If you add na overlay display of fronts (in common/standard representation) and the latest composite radar, Windy would become the best application for depiction of current weather plus how it developed and how it is forecasted to progress.
Radar overlay (for USA) already exists!
About fronts, please read my answer to the same question, here
