The Week in iOS Apps: Keepin’ it 1600

This week’s roundup includes a new and creative way to learn about how the White House works. Read on!

1600 (free, iPhone and iPad) is a playful way for people to learn about American democracy, even if American democracy doesn’t feel so playful these days. Point your phone’s camera at George Washington on the $1 bill, and you’ll be swept away on a virtual  tour of the White House.

We keep thinking that there’s no new way to do a weather app, and we keep being proven wrong. Brella (free, iPhone) reminds us a little bit of the Quartz news app, which delivers headlines SMS-style. You’ll get personalized forecasts—addressed to you—suggesting how to dress and what kind of weather to expect. It’s weather with a friendly touch.

Dawn of Titans (freemium, iPhone and iPad) boasts that it has the best graphics of any mobile game. You can be the judge of that, but we can’t deny that what we’ve seen of the game—involving battles between armies and kingdoms—looks pretty darn cool.

NerdWallet (free, iPhone and iPad) tries to help you maximize your credit. The app “uses your TransUnion credit score to determine which credit cards are right for you. Then, we’ll match you with the cards that are best for what matters to you.” And, NerdWallet promises that using that app won’t hurt your credit score.

Procreate ($6, iPad) was already pretty cool—winning an Apple Design Award earlier this year—but now it’s received a massive update that includes the abilities to group layers, import PSD files, record your Procreate screen for later video sharing, create “giant” brushes, and replace the color choices with a color wheel.

Sletters (freemium, iPhone, iPad, and iMessage) is like a mixture of crossword puzzle, Tetris, and Scrabble: “Slide letters in any direction however many times you need in order to form the words that appear on a predefined list.” The makers say this game is the perfect workout for your mind.

Space by Tinybop ($3, iPhone and iPad) lets your child explore the solar system, discovering the characteristics of each planet with the help of a “friendly snowman,” while playing games and running experiments to learn even more about life in space.

Twitterrific now includes “Center Stage” to let users view only the tweets with photos, movies, and animated GIFs … Fete (pictured) has upated its invitation-sending app … Purely Vegan offers recipes that are, uh, purely vegan.
