According to Business Insider, the wearable computing market will reach 148 million units by 2019, and each day more companies are throwing more devices throw into the proverbial ring. Apple, Google (or rather, Google's army of OEMs) and Microsoft are all fighting a battle for your wrist, and one of the most important fronts of that battle is the workplace.\n\n\nEnterprise technology isn't just big business: it's HUGE business. And while smartwatches may not have had their watershed moment in the workplace just yet, there are already several apps out there that can have an impact on your professional life if you've already taken the plunge on a smartwatch.\n\n\nHere are 5 smartwatch apps you should definitely be using at work:\n\n\n1)\u00a0\u00a0\u00a0\u00a0 Todoist\n\n\nTodoist is a cloud-based task management application that allows you to create and manage your to-do's across various projects either alone or collaboratively with a team.

For those juggling a lot of tasks, the Todoist smartwatch app gives you one more tool to help you stay organized and productive.\n\n\n2)\u00a0\u00a0\u00a0\u00a0 Evernote\n\n\nI'm guessing I probably don't have to tell you what Evernote is, as the cloud-based note application has been around for basically forever in Internet terms. Evernote's smartwatch integration is a prime example of developers having to dramatically rethink their functionality for this new interaction paradigm. The Evernote team knew that trying to recreate the experience wholesale on a watch would be impossibly cumbersome, so instead they focused on creating hyper-productive 3-5 second interactions for their Apple Watch application. You can quickly dictate ideas as they come to you, voice search across all of your notes for that key piece of information or simply check off items from a checklist, all from your wrist.\n\n\n3)\u00a0\u00a0\u00a0\u00a0 iMeet Agenday\n\n\niMeet Agenday by PGi is a smart calendar application that aggregates all of your various personal and professional calendars into a single streamlined interface.

For smartwatches, iMeet Agenday features apps for both Apple Watch and Android Wear, with features like notifications, a countdown to your next meeting and the ability to send \u201cRunning Late\u201d messages to all of your attendees directly from the watch.\n\n\n4)\u00a0\u00a0\u00a0\u00a0 Salesforce\n\n\nThe CRM juggernaut Salesforce has an entire suite of wearable applications designed to bring its analytics and notifications to the next generation of mobile sales and marketing professionals. For Apple Watch users, Salesforce provides integration with both its Analytics Cloud and its Salesforce1 Mobile App, providing at-a-glance access to insights and dashboards, critical notifications to stay on top of business priorities and the ability to easily \u201chand-off\u201d from your watch to your iPhone.\n\n\n5)\u00a0\u00a0\u00a0\u00a0 Trello\n\n\nTrello is another application designed to help you organize your tasks and projects, however Trello is based around a card interface not unlike that you'd see on a physical scrum board.
