Most instant messaging apps market themselves on just how much fun they are, with group chats, location services, media sharing, and of course way more stickers and emojis than everyone else.

Free Android and iOS app Caliber bypasses all this and goes for a different audience entirely: it’s instant messaging for your business contacts.

The key difference is Caliber’s LinkedIn integration. The app starts by importing contacts from your LinkedIn account, rather than your phone, and it keeps them synced afterwards.

Your contact profiles have all their key business details

As a result your contact profiles have the same business-oriented flavour, with details on their skills and the companies where they’ve worked.

You can also search for and try to connect with new professionals, as with LinkedIn, although here that’s even less “instant”. The system won’t hassle you with real-time notifications of any requests, instead sending you weekly summaries, and automatically removing anything you ignore for two weeks in succession.

Caliber for Android and iOS is available now.
