WeddingLan is a complete wedding organization tool. I have never organized a wedding, but I know people who have, and they often end up stressed. A wedding is a big event. This tool lets you manage pretty much all the aspects of a wedding from a single window. You can add guests, manage your budget, vendors, checklists, gifts and invitations.
An important aspect of a wedding is the budget, and WeddingLan is a great way of making sure that you don't go over your budget. In fact, the first thing that the application asks you when you start a project is the wedding's budget. When you enter that information, the app will automatically make estimates on how much you are going to spend in each specific part of the wedding, be it videography, fashion, the reception, flowers, hotels and transportation, the honeymoon, etc. It even seems to prioritize certain things over others, but thankfully you can change those values to anything you like. If you want to go over your budget, you can also do that.
Overall, the application is easy to navigate and use, although it took me a while to understand how to add attendees to the lists. What I figured out is that you first need to set up invitations and then when those are answered, you can add those contacts to your Attendees list.
In short, I think that WeddingLan is a nice tool to organize a wedding. The app seems to have every aspect of a wedding covered.
