I’m a big fan of simplicity, because it shouldn’t take rocket science to explain a service or product. One of the masters of simplicity is Philip Kaplan aka Pud, who has made some fun products that even your mom can understand.

One of his most recent creations, TinyLetter, allows people to start an email newsletter in just a few clicks. It was purchased by MailChimp in August.

Kaplan’s latest app, Bellbot, might not get acquired, but it’s yet another interesting creation from a guy who has seen it all in Silicon Valley.

The service allows you to drop a single line of code on any page of your site, and a bell will ring when someone hits it. In a TinyLetter email today, Kaplan explains the service:

I came up with the idea a long time ago when I read a story about how Jeff Bezos (Amazon founder) in the early days rigged a bell to play every time Amazon had a new customer. Also I think it’s fairly common for sales people to ring a bell (or smash a gong) every time they have a sale. So this is a virtual version of that.

All you have to do is sign up for Bellbot, and you’ll get a unique code to drop on any page of your site. To go along with the usage Kaplan suggests, you should put the code on a “Thank You” page that happens after someone signs up for your site or buys something.

After you’ve placed the code on your page, just keep your Bellbot page open, sit back and relax. As soon as people start hitting your chosen page, the app will ring. It sounds goofy, but if you’re just getting started, this type of incentive will definitely keep you and your team in the know and pushing forward to keep going.

This could be great for a charity who is having an event and wants to let everyone in attendance know when a new donation is made. As donations come through and Bellbot starts sounding off, more people will be excited to donate too. This one falls under the “Why didn’t I think of that?” category, and Kaplan is a master at churning these types of apps out.
