As co-founder of iPhone Developer’s Camp, I maintain contact with developer communities all over the world. One very passionate group has formed in the Netherlands, and has invited me to sponsor, organize, and speak during two great events. The first is a daylong hackathon:

iPhoneDevCamp Amsterdam
November 25th, 2009
11am-4pm (with lunch break)
Westergasfabriek
Attendance Max: 200 people
Also sponsored by One More Thing and PayPal

The second is a two-day conference:

iCE Amsterdam
November 26-27, 2009
Westergasfabriek
Session entitled “The Dollar App” on the 26th
Session entitled “Market Your App Through Social Media” on the 27th

One feature of these events is that we’ll have my book 140 Characters on site for purchase and I’ll be signing them throughout the week. In addition, we are reaching out to the larger iPhoneDevCamp Netherlands community with a special offer:

All students and iPhoneDevCamp.nl attendees who join us at iPhoneDevCamp Amsterdam on the 25th may attend iCE Amsterdam for 75.00€, incl. VAT (a discount of 470.00€). In addition, all qualifying registrants will receive a free copy of 140 Characters: A Style Guide for the Short Form with their purchase. Simply comment here or email the organizers to identify yourself.

I’m very excited to visit Amsterdam for the first time with my wife Meredith, and Hypertext Edition coders Jonathan Wight & Mike Lee, among other excellent presenters. We do hope to broadcast a portion of the proceedings so stay tuned for more information as the date approaches.

It was a thrill to present Big Words at the first ever App Store Showcase at the Apple Store in Downtown San Francisco. I was in august company, where we presented in this order:

Thanks to Seth Socolow who organized this, and everyone who joined us—it was a blast and we hope to do it again soon.

As soon as I can, I’ll include an audio commentary to explain some of these slides.

I’m happy to present this at any iPhone or Mobile Design / Development event near you.

I no longer work at Adobe, but have gone full time with DollarApp and my latest project 140 Characters. Adobe has recently relaunched the site, allowing me to embed this well-produced video here.

Thanks to everyone at Adobe for supporting iPhoneDevCamp and my early efforts with iPhone.

Imagine a new type of book: @BookApp.

We are interested in working with any iPhone Developer to offer 140 Characters as an In-App Purchase within their App. Just email dom@dollarapp.com.

I’d like to thank our agent, Erin Malone, for making this arrangement possible.

Thanks to you if we met at WWDC or elsewhere and you offered your encouragement!

Some comments from reviewers:

This app is great math for young and old (DaveWalter)

This app is great in its simplicity and user interface. The real-time scoring adds to the experiece. It will be a great adjunct for teaching my young homeschoolers. It make math a game, a fun game. Great use of the platform.

Great App for my Kids and Me (GlacierChaser)

I have to say, this is one of the best apps that I have used for education. There are a lot of different flash card programs out there but this is by far the easiest and most intuitive. I purchased this for my 3 boys and they absolutely love it. It has really helped them to improve the speed at which they respond to answers and of course it has helped them in learning the math better. I also use this quite a lot to improve my basic math skills -> the funny thing is that I can do large numbers in my head without blinking an eye but when it comes to simple addition such as 9+6, I actually use my fingers. I don’t really need to use my fingers, it is just a bad habit I developed as a kid. This program, encourages me not to use my fingers to count and it has really helped me with that.

Extremely well executed (ElwoodBlues)

Very well designed. I wish this was around when I was a kid!

“Math Cards” iPhone App Teaches Kids Math and Speeds Up Adult Skills in a Fun Way

San Francisco — February 12, 2009

Flash cards have been around for a long time teaching basic math skills such as addition, subtraction, multiplication and division, but they’re tedious and dull. Turning them into an iPhone App makes learning math an interactive experience that’s fun for kids of all ages. It’s even a great game to challenge adults and create faster response times.

Math Cards was developed by William Janoch of Able Mac (http://www.AbleMac.com) and has been released by DollarApp. It is available for 99¢ from the iTunes App Store at http://www.itunes.com/apps/mathcards and is in the Education category, suitable for grades 3 – 5. Math Cards is rated 4+, and will work for the iPhone and iPod touch.

Imagine math practice so rewarding it’s hard to stop

William Janoch, motivated by the desire to see his children learn whenever possible, developed the Math Cards application for his daughters (ages 8 and 9). This flash card application provides the right combination of challenge and reward to keep kids interested, without being frustrated. Math Cards replaces “I don’t wanna” with “Let me do it some more.”

Students are able to control their learning speed because there is no set pause; pauses between questions are controlled by how long the student holds the answer button. They’re eager to learn and excited to earn A+’s. The variable pace of Math Cards allows adults to be challenged and helps all ages improve fine motor skills.

Features kids and their parents love:

• Colorful cards, simple to operate
• Categories for addition, subtraction, multiplication and division
• Improves Eye-Touch coordination
• Receive grades as they go
• Easy to download and install
• Portable and fun – use it anywhere, anytime

Learning is always fun because it draws on the cutting edge features of iPhone.

DollarApp, located in San Francisco, California, develops fun games, essential utilities, and cool toys for the iPhone. Math Cards is its newest release and an example of the company strategy: one simple idea, developed in one month, and sold for one dollar.

Download Math Cards and see how much fun a dollar’s worth of learning can be!
