Sky MET (free) funktioniert nicht

Unlike most other weather apps, Sky MET presents you with the full range of international Sigmets and airmets required when preparing for your next trip, and when moving the time slider Sky MET will also provide a sigmet outlook.  Sure you can get TAFs and METARs everywhere, but you'd be hard pressed to find a map based over overview that provides you instant insight in how the weather will develop over time, just by moving a slider.  Urgent pilot reports, for instance when reporting low level wind shear or heavy icing conditions, are clearly marked in red.  These areas are displayed in on the map where blue and yellow coloration's indicate the likelihood of icing conditions.  For your convenience the reports have been categorised in Turbulence, Icing and other PIREPs.  By sliding the altitude bar you can pick an altitude that is less affected by icing conditions.  A quick glance in the left hand top corner of the screen show you the forecasted ambient temperature, wind and relative humidity.  The latter you determine weather or not clouds will be likely at that position and altitude.  Affected regions are drawn on the map along with the station summaries.  Sky MET calculates the areas with relatively high cloud density.  Use Sky MET to quickly see all PIREPs for the last hour.  Satellite images and significant weather charts are provided to complete the weather picture.
