Planning a wedding is stressful. After all, it is one of the biggest events of your life, and it doesn't come cheap. You have to pay for a venue, party favors, vendors, decorations, a wedding dress, and a tuxedo.

Instead of hiring a pricey planner to organize your wedding for you, why not take matters into your own hands? The following wedding planner apps can help you in all aspects of planning your big day.

1. The Knot

The Knot is a wedding planner that fits in the palm of your hands. It allows you to plan even the most finite details of your wedding, including a website, budget, and registry.

When you first open the app, The Knot will ask you several questions to help personalize your experience. Add a wedding location, the day you got engaged, and the expected wedding date.

From there, The Knot directs you to a dashboard that provides you with a checklist and suggested reception venues (if you haven't chosen one yet). Want to make sure your wedding stays on track? Take advantage of the app's built-in schedule to ensure your wedding goes smoothly.

You can also access The Knot from your computer's browser, making it one of the best stress-free wedding planning sites.

2. LadyMarry

Like The Knot, LadyMarry will ask you a set of preliminary questions once you sign up. It provides a wedding countdown timer to get you even more excited as the big day draws closer. It immediately creates a wedding checklist that encourages you to book a venue, start inviting guests, figure out wedding photographer, purchase outfits, and choose flowers. And don't forget to make a note to create and send out your "Save the Date" cards!

If you opt to book any services through LadyMarry, it will redirect you to a third-party website like Thumbtack or Yelp. As you go through the planning process, the app also provides you with helpful tips and tricks for your wedding.

3. MyWed Wedding Planner

MyWed offers a more straightforward approach to planning your wedding. It doesn't come with a built-in ability to find vendors, but it still allows you to contact them through the app once you input their information. Basically, it functions as a virtual address book.

The app also helps you keep track of your budget. Just input any expenses, along with how much you've already paid and an estimate of the amount you might spend. Additionally, MyWed gives you an easy-to-follow checklist to make sure you plan out your wedding essentials (like a bachelor party and a bridal shower) before the date of the wedding.

4. Wedding Planner

Wedding Planner's user-friendly design makes it simple to add any events you need to get done, along with expenses, vendor contacts, and guests. If you don't feel like adding every single event to your checklist, Wedding Planner adds defaults. Thus you won't have to create events for your engagement party or budget research; you'll just have to adjust the due dates.

Wedding Planner also gives you a rundown of your actual wedding day. While you can always customize it, the schedule comes pre-loaded with events for the whole day, starting from the moment you wake up to the second you cut the cake.

If you've just started planning your wedding, don't fret. WeddingWire provides plenty of inspiration to help you get a running start. You can check out creative wedding invitation ideas, flowers, cakes, and rings. The app even gives you the opportunity to talk with other engaged couples in the process of planning.

When you're ready to start making a budget, WeddingWire allows you to set up an estimated cost, as well as the prices of any services you're using. You can even add guests, establish a registry, keep track of vendors, create a wedding website, and invite your fiancé to the app in order to help you plan.

6. Bridebook

Bridebook helps you plan your wedding months in advance. It automatically gives you detailed tasks to complete each month before the wedding date. Bridebook prompts you to check off assignments like inviting guests, picking a venue, and choosing bridesmaid dresses. This way, you won't forget about any wedding essentials.

You can also use Bridebook as a budgeting tool. Once you add your target budget, input the number of guests, determine the season of your wedding, and decide whether to purchase extra wedding services, Bridebook will generate the amount you should spend on each aspect. This tool can definitely help you prevent overspending or underspending on certain items, all while maintaining your budget.

You can also use Zola to add gifts to your registry. The app lets you shop around for kitchen goods, home essentials, travel accessories, gift cards, furniture, and bathroom basics. Once you find an item you like, you can add that specific product directly to your registry.

Like the other apps on this list, Zola allows you to plan out your entire wedding. You can add events, view a wedding to-do list, and even plan your honeymoon.
