Lake: Coloring Books is an art app for children and adults. Use five tools—acrylic brush, watercolor brush, spray, fill, and an eraser—to add up to 245 colors to your photos. Lake gives you one free drawing per day, but if you choose to subscribe to the app—which helps support the artists that provide the illustrations—you'll receive more outlines, gain access to art from featured artists, and unlock more color palettes. It even works with Apple Pencil if you're using a compatible iPad. Once you are done, you can save, share, and print your masterpieces.
