One almost unnoticed innovation in our modern world is the tracking app. Whether you’re booking a car service, enduring a long flight or just waiting for a pizza, with a click or two, you can find out exactly how long it should take the car, flight or pizza to reach its destination. These apps are useful for planning purposes and provide a level of reassurance that you are, in fact, headed to where you should be headed. A similar monitoring of the downward path on inflation can provide some reassurance that inflation is, indeed, on track to hit the Fed’s 2% target ahead of schedule.
