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.
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.
