6. CamScanner. Got a homework assignment or drawing you want to post or share? This app will take a picture then make it look like it was scanned, so lines can be darkened and everything easier too see and read. It really beats the hell out of bad lighting and blurryness. All without a scanner.
7. Anylist. Basically an app my wife and I use primarily for shopping. Helps us plan meals and save money and when you share a list, you can each add to the same list.
8. Sleep Cycle. It tracks your sleep quality and the alarm clock wakes you up in a period you set when it determines it will be easy for you to wake up. Works like a charm, makes mornings easy.
