What's the sitch?
Mankerl is the marmot in your weather app. It tells you not just what the weather will be, but when to go for a run, fire up the grill, head to the lake or hang out the washing. Coming soon for iPhone and Android, first in Germany, Austria and Switzerland.
Weather that tells you what's possible
Windows, not just numbers
Mankerl scores every 15 minutes for your activities and tells you the best time: run at 17:30, grill from 18:00, do the garden once the wind drops.
Just ask
"Can I dry my laundry outside today?" Mankerl answers in your tone: matter-of-fact, cheeky or caring like your gran. And sticks strictly to the forecast.
Weather worth sharing
Photo or video, with the temperature, the place and a cheeky one-liner on top. Ready for Instagram, TikTok and WhatsApp. Your photos stay on your phone.
Mankerl shows you the sitch
When it gets dangerous, Mankerl gets serious: official warnings from DWD, GeoSphere Austria and MeteoSwiss come straight, with no jokes.
