What Acompli's recent roll out to the public and its highlighted features include simplifying email so that users can check their email easily on the move.

Accompli, regarded as the best email app for iPhone 2014 supports Gmail and Microsoft, accounts that are mostly used on smartphones like the iPhone 5. Accompli enables exchange of email accounts and features faster search functions, an in-built calendar and file discovery.

Acompli CEO and cofounder, Javier Soltero says apps like Mailbox, which emphasize deferring messages, don't actually improve the experience of using email on a mobile device.

"Email is what ties these two worlds of personal IT and corporate IT together," Soltero told Mashable. "Email, particularly when it comes to mobile professionals, is pretty limited. It's almost like we've given up on building a truly innovative experience that leverages the capabilities unique to smartphones."

According to Soltero, Accompli's objective is to solve the most common issues users experience when using email on their smartphones. Perhaps the worst problem associated with mobile is app switching.

In order to solve this, the company built a full-fledged calendar into Accompli so that users can check their calendar without exiting their email.

The app also enables faster attachment discovery by putting emails with attachments in a separate section of the app. This allows users to quickly find files that have been emailed to them, even if they aren't stored locally on their device.

Similarly, the app also has a separate section for people, where users can see a list of all their recent contacts and any files or meetings shared between them. Acompli also includes predictive search to cut down on the amount of touch screen typing necessary to find what users are looking for.

Accompli is currently iPhone only but Android and iPad versions are in the works for later this year. Acompli is available in the App store.
