Event planning is a notoriously complex process that involves hundreds of tiny details and decisions. Whether you're brainstorming theme ideas, organizing volunteers or checking in guests, the right events app can help you manage your workflow and keep track of moving parts. Since each mobile event app is available virtually anywhere on your smartphone or tablet, they can eliminate the need to carry around cumbersome spreadsheets and printed pages. With a wealth of information at your fingertips, you can make faster decisions, avoid missing key items, and promote your event

Evernote

You can keep your event-planning team on the same page with Evernote. This app can make it easy to capture and organize information in seconds from virtually any device. Consider creating a "notebook" for the event and use it to collect everything from your running to-do list to vendor contracts. You can take a photo of a receipt immediately after you buy cups and plates, and send it to Evernote; that way, you don't have to hunt for it later. You can allow everyone on your team to access the notebook so they can contribute notes from venue research, travel documentation, relevant news articles, or inspiration photos. Evernote also enables you to delegate tasks directly in the app and monitor when each one is completed. With the app's advanced sharing permissions, you can control exactly what each team member sees. A powerful tagging and search tool makes it easy to find any email, photo, scanned item or note in seconds. Evernote offers both free and paid plans.

Pinterest

Pinterest is a free visual bookmarking tool that enables you to save items from the internet to photo-based boards. When you're planning an event, the Pinterest app is a good way to collect ideas for themes, decorations, party favors, invitation designs and venue options. Pinterest itself is a good search resource; simply enter a term, such as "office holiday party," into the app to see a huge collection of related pins that you can save to your own boards. If you find an item or a photo online, enter the URL into the Pinterest app to save the image. The link is automatically saved for easy access in the future. The app also enables you to upload photos from your phone to a Pinterest board, so you can collect inspiration while you're at another event or if you see a beautiful banner on display. When you're in charge of an event-planning team, you can allow other employees to contribute ideas by adding them as collaborators on your event's Pinterest board.

Events XD

Events XD is a desktop and mobile conference app that streamlines the event-planning process. You can use it to build and customize a free website, promote your event and sell tickets. The app also enables you to organize individual sessions into color-coded tracks, so attendees can find what they need faster. When your attendees download the app, they can add sessions to their personalized agenda -- and since you can add digital floor plans to the app, guests can always find their way around. During the conference, the Events XD app allows you to send notifications and updates directly to attendees, share news, and post to social media accounts. Events XD is a free events app; paid add-ons are available for customized branding to match your marketing materials, ad-free sessions, and more.

Eventbrite Organizer

When it comes to tracking participants, the free Eventbrite Organizer app can be an easy-to-use option. You can simply connect the app to an event you've set up in Eventbrite to get real-time data access from any location. Consider using live ticket-sale tracking before the event to decide when to put out an extra marketing push or deploy a special discount code. One of the app's most useful facets is its check-in feature -- simply tap on an attendee's name to check him in. If you have a long guest list, you can use the built-in scanner to read the guest's ticket barcode and bring up his details immediately. A payment-processing feature enables you to make ticket and merchandise sales on site. As your front-of-house staff checks in each person and sells additional tickets, the app provides live attendance stats. You can access that information from anywhere in the venue and make on-the-spot decisions about catering and security, all without racing back and forth from the check-in station.

Eventful

Eventful is an app dedicated to showing users what events are going on. To use this app, simply create an account and add an event. The app prompts you to enter all the pertinent details, from the description of the event to the location of the venue. You can also tag your event with categories, such as film, technology and conferences. When a user is looking for things to do locally in your category, your event pops up as a possibility. This enables potential attendees to find out about your event even if they don't see any of your other marketing efforts. Listing an event with Eventful is free.

With the right apps, you can power through the event planning and promotion process with minimal hassle. From coming up with a theme to monitoring guest levels at the door, a mobile event app can help your party go off without a hitch.
