Mobile Apps

While most of our work is done as private-labeled apps for others, we do have a few apps available under the Portable Knowledge name in the Apple App Store, Google Play Store, and Amazon Appstore.  Check them out today!

KnowledgeBook: Cooking

posted Mar 22, 2012, 9:23 AM by Jeff Hay   [ updated Mar 22, 2012, 9:54 PM ]



KnowledgeBook: Cooking doesn't contain any recipes, but cooks will find this app indispensable. Instead of recipes, KnowledgeBook: Cooking has all the tidbits of information that anyone putting together a recipe really needs. This app's handy reference guide includes ingredient substitutes, a comprehensive culinary glossary, measurement conversions, and temperature information.

Discover what can be substituted for buttermilk, how many bananas it takes to make one cup of slices, how many cups are in a pint, and what temperature an oven should be set to if the recipe calls for a "moderately hot" oven. This app also helps you decipher arcane kitchen terms such as "papillote" and "chiffonade." KnowledgeBook: Cooking also includes cooking instructions for high altitude as well as a comprehensive yield list of fruits, vegetables, and other ingredients, from apples to yeast.

This app features a measurement calculator that makes unit conversion a snap. When you are on the measurement screen, select which measurement you wish to convert, and a calculator will come up. You simply tap in a number, and viola! Your measurement is automatically converted in every relevant unit. For example, if you enter in "3" for tablespoons, your 3 tablespoons will be converted in general, US, Imperial, Australian, metric, informal, and even ancient measurements.

Dedicated to the honor of the Flag of the United States.

When should the flag be flown at home? Where should the flag be placed on stage in relation to a speaker? Should the flag be draped over a podium? How was the US Flag of WWII different from today's flag? What are the words to the second verse of the Star Spangled Banner? What are the only two states to be admitted to the union (thus adding stars to the flag) on the exact same day? What RGB color values should be used when drawing the flag on a computer screen? How should the flag be folded for display?

KnowledgeBook: US Flag answers all these questions and many more.

"Crosstalk is a simple, powerful XMPP client that is easy to set up and just works. Using it with Google Talk is a wonderful way to go. I love its support of background messaging on the iPhone 4, and as a universal app, I can have it on my iPad, where it is awesome....I've also been using it for Facebook chat, and it's great for that."

"Best XMPP app out there! I've got it logging me into Google talk, my company's IM server, and my own OpenFire XMPP server. Works great, even when you're logged in from your desktop too."
