Readdle's incredibly efficient (and free) email client, Spark for iPhone, has just gotten a whole lot more useful with full support for Microsoft Exchange accounts in the latest update in the App Store.
This was the main feature request from thousands of people who wanted to use Spark with Exchange in the workplace, developers tell me.
Even more exciting than that, the team has confirmed that they're hard at work putting finishing touches on Spark for iPad, which should be released “soon”. In addition, a spokesperson for the company tells me via email that their next step will be “creating the best email client for Mac.”
