VisualMath 4D is a professional graphical calculator. It allows you to browse through a collection of built-in functions like trigonometrical, rounding, and sum and product or you can compute your own. Functions can be drawn in 2D, 3D, and 4D all with a time variable. You’re also able to save your functions, rotate and zoom in on the graph in three dimensions, and display multiple graphs at once.

Captain Cowboy is pure nostalgia. You’re able to explore a massive handcrafted world with only the swipe of your finger. Dig through debris in search of diamonds, push unbreakable boulders out of your way, and cross paths with friendly Snorkhogs and dangerous Gnurfs. Whatever you do, avoid getting sucked out into the abyss and smashed by avalanches of boulders. There’s so much to see that you’ll need to access your handy auto-map from time to time in order to stay on track.

War of Eclipse is unabashedly retro. Its pixel art graphics are sharp and its gameplay brutally difficult. You’re able to choose from seven powerful battleships, each of which can be customized in a variety of ways. Blast away all kinds of alien invaders by perfectly timing your shots. The game includes 35 enemy types to take on, random equipment drops, and seven different endings to discover.
