Fussball im TV 2.0 für iOS erschienen
Heute ist es endlich soweit: Die App Fussball im TV ist seit heute in Version 2.0 im iOS AppStore erhältlich!
Insgesamt erreichten wir ja auch mit der ersten Version bereits über 200.000 Downloads, aber während sowohl die Android-(135.000 Downloads) als auch die Windows-Version (50.000 Downloads) sehr erfolgreich waren, dümpelte die iPhone-Version mit nur 15.000 Downloads nur so vor sich hin. Das ist eigentlich auch gar nicht so verwunderlich, denn gerade die iOS-Version beschränkte sich wirklich nur auf das Wesentlichste. Was lag als näher als die App für iPhone und iPad komplett neu zu entwicklen? Diesmal natürlich direkt mit Xamarin Forms.
