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.

Math Cards version 1 has been removed from the App Store. Math Cards 2 is now shipping from AbleMac for $1.99.

Thank you to everyone who bought Math Cards version 1 and all of you who reviewed it!

We still have Big Words, and there is more coming soon from DollarApp.

DollarApp is thrilled to announce its support of iPhoneDevCamp 3, taking place at Yahoo! in Sunnyvale. Hundreds of Designers and Developers for iPhone and iPod touch are expected to converge on July 31 through August 2nd – check out the Agenda!

The event is inspired by BarCamp, SuperHappyDevHouse, and MacHack, to develop Cocoa Touch and Web-based applications for iPhone and iPod touch. This follows the previous iPhoneDevCamp events held at Adobe Systems in San Francisco, July 2007 and August 2008. Out-of-town guests are welcome.

Attendees will include Cocoa Touch developers, web developers, UI designers, and testers, all working together over the weekend. Development projects will include both solo and team efforts. While some attendees will wish to work solo during the event, we encourage attendees to team up, based on expertise, to work in ad-hoc project development teams. All attendees should be prepared to work on a development project during the event.

Registration is now open.

Attendees will be able to:

• Create new applications for iPhone and iPod touch.
• Migrate Mac OS X applications to iPhone and iPod touch.
• Test and optimize applications for iPhone and iPod touch.

The event will feature:

• Simultaneous Events Worldwide
• Meetup Time on Friday with Refreshments
• Catered Breakfast, Lunch, and Dinner on Saturday and Sunday
• Saturday Keynote (TBA)
• Open Mic for Questions
• Ad Hoc Sessions by Participants
• Late Saturday Gaming
• Sunday Keynote (TBA)
• Hackathon Contest

Last year was an incredible success: the winners went on to do righteous things, and the sponsors saw tremendous growth. We doubled the previous year’s attendance:

We expect this year to more than double the size and scope of the event. In order to cover the additional overhead, we may need to charge a small fee (up to $50) for folks to book a spot at the event.

We are committed to staying not-for-profit; all charges will go toward the production of iPhoneDevCamp, and the founders don’t make a cent. The founders are Raven Zachary (who had the original idea), Dom Sagolla, Christopher Allen, William Hurley, and Blake Burris, with the honorable Chris Messina presiding. We are currently seeking:

• Sponsors
• Donations
• Volunteers

To get involved with the above, please email Raven and Dom: info@iphonedevcamp.org.

We can’t wait to see what awaits us this year! For now, we’ll leave you with That Phone Guy:

The folks at FITC Mobile have invited me to deliver an update to the speech that launched DollarApp, entitled “Why A Dollar“. I’ll be talking about the strategy behind “140 Characters“, the hypertext book app coming this Fall.

By all accounts, this conference is not only action-packed, but also a huge party. Check out the highlight reel from the last one:

FITC Toronto 2009 – Highlight Reel from FITC on Vimeo.

If you have the means, I highly recommend attending, September 12-14, 2009 in Toronto, Canada.

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!

To activate a new layout, just add a space at the end of your multi-word message. This will add an extra line break. Here’s “Help me!” without the space:

Adding a space to the end of “Check please” really changes the layout. See without space:

Here we see how the touch-and-hold feature works to provide additional feedback to the learner.

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!
