&gt; On August 31st, we’ll officially shut down the app and it will stop working all together.<p>So based on this, I assume that all access to your calendar server (iCloud, Exchange, Google Apps, etc) was managed through a centralised server(s) that Sunrise used... for something.<p>Maybe the next time someone claims to be a funky new take on &lt;boring office task&gt; just do a little checking. We&#x27;ve had desktop and mobile device clients for mail, calendaring, contacts etc for literally decades. Why <i>now</i>, when we have more computing power available to us than ever before, do we need <i>another</i> server (operated by a company that&#x27;s more likely to disappear than not) between us and our mail&#x2F;calendar&#x2F;contacts?
