EyeballReadFaster How fast can you read? Fast enough to be successful? An average adult reads ~250-300 words per minute; check your speed here.  Some cool cats over at Spritz have designed a speed reading app! If you flash one word at a time - in the same spot - it can save you time  from moving your eyes around a page. You can even choose different speeds (350, 500, 600, etc). See if you can read faster now.
LungCapacity How healthy are your lungs? Now you can test how efficient your lungs are, right from your own smartphone! An app called SpiroSmart acts like a spirometer, and even comes quite close to the accuracy of medical spirometers. All you do is take a deep breath and breathe toward your phone, which analyzes the reverberation of your lips. Have you ever used this app, or a spirometer before? I would love to hear your stories below.
