I just took this photo. I’ll tell you about it later.

I tested an idea that aims to change that practice: Appy Couple. It functions as a couple’s official wedding app and guides guests through a wedding. They can use it to track information about the bachelorette party or other pre-wedding events, and on the wedding day to find their way to the venue and post photos that they take. While many existing wedding apps help brides and grooms plan things like seating arrangements, dress selections and registry creation, this app is a mobile aid for guests.

Appy Couple comes from a New York City-based start-up called AppeProPo Inc., and it has a couple of rough edges. For example, users can’t crop uploaded images and it is difficult to navigate the section where virtual Champagne toasts can be posted. The company plans to fix these issues soon.

Appy Couple has features tailored for guests, who can upload photos, get travel and weather information and vote in polls.

Last year, I spent weeks making my own wedding website, and very few of my tech-savvy guests used it or visited it more than once—if at all. I only wish Appy Couple had been available for my wedding, where most guests carried iPhones or Android phones.

This app-creating website is currently free to use, and it will always be free for guests to download; they follow an email link or use a provided code to access their couple’s wedding app. Readers of this column can create their own wedding apps on AppyCouple.com using their email addresses and “AppyPreview” as a code, since it is currently usable by invitation-only. In the fall, AppeProPo will start charging couples to make apps: Some designs will cost $49, while limited-edition and designer-series app templates will cost $99 to $200 each. One hundred designs are available now, and 50 more are coming by fall.

Appy Couple works on iPhones, Android phones, iPads, Web browsers and via email invitations.

Couples begin on AppyCouple.com, where a stylish, simple user interface walks them through seven steps for making their wedding app. Each app also comes with a wedding website that will display the same content for relatives or friends who don’t have smartphones.

One of my favorite parts about creating a wedding app was that I could change its design at any time. I started with a yellow-and-gray bubble design and later changed the design to a completely different black-and-gold pattern. With one click, the entire app was updated.

Another useful feature is the Events section. Only guests who are invited to certain events will see those events appear in their apps. So if only 15 friends are invited to the bachelorette party, only they—and not the rest of the guests—will see it. Couples can customize Events to add songs, guest polls, information on dress code, child care, weather, travel and hotels.

Appy Couple connects to Facebook, but only for the purpose of pulling images and names of friends into a section called Key People. It will never display any Appy Couple activity in your Facebook timeline. It also links to Yahoo, Google, Windows Live, AOL, Plaxo, Outlook and Apple’s Address Book for finding friends’ email addresses.

Judging from the many weddings I’ve attended, Appy Couple’s Gallery will be the most-used section on the app. In the test app I created, friends uploaded photos that can be viewed by the couple and other guests, and the app grew richer with their contributions. Images can be uploaded without pre-approval from the host couple, though any image can be deleted by the hosts on the AppyCouple.com website. A “moderation” option will be added to the app to give the couple more control over content.

A guest list can be uploaded to the app, but it must be saved as a CSV (comma separated values) file with columns for each guest’s first name, last name, email address and phone number. Couples who use traditional response cards will likely not also digitally invite guests to their wedding, but casual wedding events might merit a digital invitation.

Appy Couple’s CEO and co-founder, Sharmeen Mitha-Sehgal, wants couples to use personalized apps long after their wedding day. Next up is Appy Life, where people can create apps for events like births, birthdays, new homes and anniversaries.

This app brings useful wedding website content on the go with guests as they attend weddings. If nothing else, they’ll know how to get to the church and when the ceremony starts—even if they forget to bring the paper invitation.

Here’s a delicious juxtaposition you don’t get often: Various reports indicate that reality show empress Kim Kardashian’s upcoming wedding to New Jersey Nets basketball player Kris Humphries will be held at the Montecito estate of Google’s Executive Chairman and former CEO Eric Schmidt.

And, according to another report, if not there, then at a house owned by one of Silicon Valley’s most famous VC legends.

Schmidt won’t be a guest at what is sure to be a heavily chronicled event — which the New York Post said will have a $20,000 cake, three dresses and 500 guests.

You know, simple nuptials.

Instead, it appears Schmidt rents out the lush house, which he bought from talk show host Ellen DeGeneres in 2007 for $20 million.

Fun fact: It is the same spot where Jennifer Lopez and Ben Affleck — or Bennifer, as I like to call them — were set to be hitched in 2003, before they called off their engagement.

According to blog site The Real Estalker, who also wrote about the possible rental:

The privately situated and heavily secured luxury compound’s architectural heart and soul is a 5,000-plus square foot main house with 4 bedrooms and 4 full and 2 half bathrooms designed by beloved Santa Barbara architect George Washington Smith. Staff and/or guests can be comfortably accommodated in a detached 1-bedroom guest house with kitchen and an additional studio space tucked into a quiet corner provides private respite from family members and all the full-time staff people required to maintain an estate of this magnitude.

At the time Mister Schmidt snatched up the property, the extensively and meticulously landscaped grounds included a long winding drive, massive motor court, championship grade tennis court, extra-long swimming pool with raised spa area, wide terraces, broad lawns, and a stunning allée with colorful tiled fountain that screams out for a highly stylized celebrity wedding designed — we presume — by an efficient, innovative and extremely well-paid event planner.

[UPDATE:] Later, The Real Estalker changed its report and said the wedding might not be held at Schmidt’s place, but at another over-the-top estate owned by Silicon Valley venture legend Frank Caufield, one of the founders of Kleiner Perkins Caufield & Byers.

I have a call in to the Kardashians, who are usually so shy with the press, so I will update as soon as I hear or a camera crew arrives at my house.

Until the I-dos are done, below are some pretty pix of Schmidt’s fancy spread from back in 2006:

A Google spokesman had no comment, obviously.

As part of the save-the-date cards they sent out earlier this month, the couple included specialized bar codes, known as QR codes. The two-dimensional bar codes, which can be scanned in with any smartphone, have become popular in advertisements, products and even as markers at points of interest.

But Chalaban, a PR consultant for tech companies, thought the codes might also serve a useful function in preparing for their special day. One code on the card takes guests to the wedding Web site, while a second QR code adds the ceremony to their guests’ calendar.

“We’re both kind of geeky, and, since we knew we couldn’t go as far as sending all communications digitally (for those guests who aren’t tech-savvy), the QR code printed onto the traditional save-the-date seemed like a good bridge,” Chalaban said. “We like the QR code because it gives you immediate information and/or something beyond what’s just on the save-the-date card.”

The couple isn’t stopping there, though. Chalaban said they are also thinking of including a code on the invitation itself, in an effort to automate the RSVP process.

The one downside, Chalaban said, is that the codes are, well, a bit ugly.

“We tried to make it more aesthetically appealing by changing the color to purple rather than the plain black,” she said. “This is why we put the QR code on the back of the save-the-date, rather than the front.”

Chalaban may be a bit dismayed to learn she isn’t the first to think of incorporating QR codes into wedding invitations. Los Angeles-based Paperspring, for example, incorporates the codes into everything from wedding invitations to baby announcements, while a number of wedding forums also buzz about the approach as the latest thing since replacing the DJ with an iPod.

Update: I even found someone who tried to integrate a QR code into the wedding cake. I think that might be taking things a bit too far.
