In their own words:

The Tip Card is a mobile app built for the iPhone that allows users to rate their server experience at a restaurant.

Have you ever left a tip for a server, but also wanted to express your happiness, or unhappiness, at the service they provided? Well now you can. The Tip Card is a vehicle to provide your rating of a server and let others know about it, helping your friends steer clear of a restaurant or a particular server, or encourage them.

The restaurant experience is based on six major interactions with your server. At each of these points we ask you to rate your server’s performance, which results in a total score, which you can then use to calculate tip.

Login through your existing foursquare account, or create a new account through Tip Card.
Locate the restaurant you dined at using GPS in your iPhone.
Enter the date, time and server’s name.
Rate your server based on six major contact points with your server.
Add any comments.
Your rating is uploaded to our database for other users to view.
We also provide a helpful tip calculator which can guide your tipping procedure.

Other features include:

Share your ratings with your friends.
Automatically checkin through foursquare when you rate a server.
Share your rating on Twitter or Facebook.
Share your comments through foursquare’s “to do.”
Search for a restaurant in your are by proximity or cuisine.

Zack’s take:

First things first…you need a Foursquare account. I didn’t have one so it was a bit of a nuisance to get one…but I probably should have done that years ago anyway. Once you download the app, the foursquare integration is kind of funky…if you don’t know about authorizing apps, you won’t know to scroll down the login page on the app to click the button. Anyway, once I got through that the app crashed once. No problem though…that happens to a lot of good apps. Since I didn’t have a foursquare app I didn’t have any dining history to rate and test the app so my review won’t be completely informed. Anyway, the site is pretty straight forward…I don’t like the logo but that’s my problem. As far as the idea goes, I have to be honest, I just wouldn’t bet a lot of money on it. This should be something that Foursquare integrates out of the box in order for it to work. That may be just what the owners are going for but they’ll need a bigger following to get to that stage. I’d like to wish the creators good luck nevertheless.
