I wanted to report that my climbing partner and I got #Covid but the German and Austrian #CovidApp have ceased tracking and the Dutch app has never worked for me anyways. But I wonder why the apps have been phased out. Wasn’t there a huge potential for tracking future virulent strains once a large part of the population endorsed the use of the apps? Wouldn’t this data be still useful today? Is this not a wasted effort to develop and promote the app and not maintain its use?
