The app offers the possibility to use different tools mobile and promptly directly at the place of departure.

Checklist: Did we really think of everything? The checklist is the ultimate control system, so you're guaranteed to make no mistake during the excitement on the launch day. Helium Calculator: How much helium / balloon gas does my weather balloon need? Calculate the required amount of helium / balloon gas directly at the launch site or adjust the ascent rate / maximum ascent in the last second, for example. Flight route prediction: Where does my probe land if I start the weather balloon in the next two minutes? Use the mobility of the app to accurately predict your flight path to within a few miles and, if necessary, to adapt to changes in the amount of helium / balloon gas.
