About HowHigh - Barometric pressure measurement tool

HowHigh is a super-simple tool for your iPhone 6 and iPhone 6 Plus that allows you to measure anything in your world too big for a tape measure. Just choose a surface to measure from, start raising your device, and HowHigh will display the distance your phone has travelled upward from your starting surface (measurable in inches, feet, or yards).

HowHigh uses the new barometric pressure sensor built into the iPhone 6 and 6 Plus to estimate altitude gain based on the change in air pressure. This means the readings are accurate to within just a few inches. So take it on a Ferris wheel! Take it up a skyscraper! Take it on a hike! When you have to know how high something is, ask HowHigh!
