I’ve been testing Readdle’s new mail app, Spark, for the last week or so, and it’s really good. As you might expect with a major new iOS productivity app, Federico Viticci has written one of his epic-length reviews, which you should definitely read.
I’ve been using Spark for the past three weeks, and it’s the most versatile email client for iPhone I’ve ever tried. It’s also fundamentally limited and incomplete, with a vision that isn’t fully realized yet but promising potential for the future.
To me Spark’s biggest missing feature is support for the iPad. It’s hard to rely on one of these “email-plus” clients and only use it on a single device.
