Show HN: ClassPager lets teachers send reminders and run live Q&A over SMS.

First - the site: I love the simplicity. The concept is clear immediately.<p>Second - the service itself: it's a great angle. Kids love SMS messages and this embraces the use of technology/cell phones in a positive way. It creates a more personal connection between teachers and kids without breaching privacy. We had something similar, though far more basic, when we were working on an LMS and that was a highlight we often overlooked but got the most vibrant response.<p>Great work so far!

Nice Concept. We're just starting the school process (4yr old), and I'm amazed to see all the use of tech in schools these days. When I was in school, we were lucky to have an Apple ][ in the library!<p>*Question: On your business model, are you hedging that paid classes ($9.99 / month) will just stay under 1,000 texts (Based on twilio .01/per rate) in aggregate and thus leave a little profit for you, or is there more to it?<p>If there is not more to it, it seems like the 'unlimited' could be risky (unless your unlimited is really like AT&#38;T's 'unlimited' data plan :-) ).<p>A class of 25 students might encompass 35-40 devices (including parents). @ 40 devices 1 broadcast per school day is $8.20 cost to you. This does not include for responses, multiple sends per day, etc..<p>I know you've thought through all this, and probably have great answers, I'm just always interested to hear how others think about their price models. Thanks for sharing.

Nice site. Since I'm currently viewing this on IE7 (shoot me now), I can see that you have an error in you conditional IE comment so I can see it at the top of the page:<p><pre><code> &#60;!--[if IE lt 9 ]&#62; &#60;![endif]--&#62; </code></pre> should be:<p><pre><code> &#60;!--[if lt IE 9]&#62; css &#60;![endif]--&#62;</code></pre>

This is really neat. A few of my relatives are high school teachers that I'm sure will love this. I'll forward it to tem.<p>Also, great name. I've seen others in this space with names that aren't quite as clear as yours, which is important for the demographics you're targeting – teachers and parents.

This is exactly how you sell this kind of services. No fancy web design, no over complex messagin, no geek speak. Just straight to the point communication. (I say this as a designer)

I think this is really awesome and definitely headed in the right direction as far as getting teachers more involved with technology, however from my experience in several different schools, most have been really strict on cell phone use during school and teacher/student communication outside of school.<p>It was quite a hassle really because teachers wanted to do more but were restricted by school policy. I hope schools start to utilize technology in the classroom.

Do you have any traction yet?<p>My friend does the same thing <a href="http://www.tophatmonocle.com/" rel="nofollow">http://www.tophatmonocle.com/</a>

My wife is a middle school teacher and created a system similar to this using a Gmail account. She creates groups for each class, then emails to their SMS address (phonenumber@att.net or similar).<p>This looks so much nicer than jacking around with all the various carrier email addresses manually.<p>I'll have her pass this along to her district. Best of luck!

I like the clear, easy to understand site. Sounds like a useful product.<p>Are you marketing this to teachers or the schools?

Really awesome application! I passed it along to a couple of my teacher/professor friends.<p>Hopefully this can replace a lot of those awful RF-based polling systems that come packaged a lot of college level textbooks. Physics II in college was really painful because of our 'clickers'.

Great UI, and I love the signup interface. Just emailed it out to a bunch of my teacher friends.

Teachers are looking for stuff like this so the key to success is spreading the word. There certainly are competitors in your space (ClassParrot etc)<p>Just curious. Why did you choose to use Twilo as your SMS provider?

Here's what I think:<p>1. Great idea, especially considering the attention span of a student can be somewhat diluted with so much modern technology - incorporating that same technology is a great hook.<p>2. Color scheme is good, and so is simplicity, but while erring on the side of simplicity is better than erring on the side of a very busy screen, it's still erring. While your concept is clear and concise on the home page, I personally feel as though there is too much white space (again, this is not a color scheme issue, but an issue of not enough going on).<p>3. What is the stated problem that you are trying to solve with this technology? In other words, what is the hook you can use to relate to your audience and persuade them to use the product?

This would be a great feature to integrate with ClassCloud, which is a cloud based classroom management system. I hope the class pager guys release an API! Would make my life easier.
