Taking a break from the bubbly and colorful tones of Beat Sneak Bandit and Bumpy Road, Simogo's latest iOS game veers off into much darker territory, offering a completely different yet equally rewarding experience. While it starts off innocently enough, Year Walk quickly spirals out into an enthralling puzzle adventure steeped in haunting imagery and supernatural mystery. It keeps you guessing at every turn, but locks you in its grasp with smart challenges and heavy atmosphere. The best part is that your detective work doesn't stop once the end credits roll.

We have dozens of ways to take notes on our iPhones, and while some have exquisite, minimal interfaces, others are feature-rich powerhouses that try to mimic desktop functionality on a mobile device. Write for Dropbox wants to be everything at once, and it comes as close to succeeding as any app we've ever used. By utilizing a nifty three-panel interface – with a tool bar, document list, and main writing window – Write deftly uses every inch of real estate at its disposal, with oodles of sharing options and one of the most powerful virtual keyboards we've ever used.

You don't have to be a great artist to have a good time fiddling around with DrawQuest. This goofy little social art app for iPad encourages you to draw something new everyday by giving you a prompt to follow, and then pitting you against other artists to see who can come up with the most clever sketches. It's a cool way to jump-start your creative spirit, but the real fun comes from sharing your creations with the game's thriving community and voting on your favorite doodles.

When you think about it, the calendars on our iPhones aren't all that different than the ones that hang on our walls. Sure, we can set alerts for 2037 and fit much more than we can on those impossibly small squares, but for the most part, digital calendars haven't brought much new to the game. Horizon Calendar might not be a revolutionary change to mobile calendaring, but it's a good start. Its fresh, clean interface puts your events front and center with color-coded appointments and locations, and best of all, weather reports.
