  • 3No. 3: Intro to Letters

    Cost: $4.99

    Who: Bobby George, co-founder of Montessorium

    What it offers: George runs the first accredited Montessori school in South Dakota, and wanted to translate the classroom experience to an app in order to bring it to a wider audience. “It was an unprecedented opportunity to reach kids on a scale we had never seen and democratize Montessori,” he says.” Intro to Letters teaches children the basics of the alphabet, while Montessorium’s newest app, the self-explanatory Intro to Cursive, will launch this week.

    Entrepreneur story: George says Montessori traditionalists were originally opposed to the apps, as they don’t believe in technology. But soon after launch, George received an encouraging email from none other than Steve Jobs, who told him not to get discouraged, and that the parents and kids would prove his app’s worth. Since then, Montessorium’s apps have been featured in iPad commercials, and on an international iPad billboard campaign.

    Cost: Free

    Who: Jeremy Olson, founder of Tapity, Inc.

Olson originally designed it for college students but says it’s widely used by students in middle school and high school as well. Grades version 3 will be released this week, and will help students remember due dates and set reminders.

    Entrepreneur story: “I got a D on a fateful statistics test and wanted to know how to recover back to an A,” says Olson. After doing the calculations on pen and paper, he realized it would make a great app for students. Olson’s other educational apps, including Languages, a translation dictionary, have also made an impact in the app community.

    What it offers: Endless Alphabet offers kids the opportunity to learn their ABC’s and build vocabulary, with over 50 words to learn through animations. With 25+ years’ experience in Silicon Valley, Ishibashi says the app is designed to add value in short sessions, since most kids use devices that are passed back to them for brief periods of times by parents or older siblings.

    Entrepreneur story: “We knew we had to entertain and educate to feel good about the app experience,” says Ishibashi.
