MeasureMint vs Cliff Timer

MeasureMint™ is like a magic tape measure. Using the new Augmented Reality features of iOS 11, MeasureMint allows you to place an anchor anywhere in space you can place your iPhone and then measure the distance between that point and wherever you then move your iPhone to. Think of it like a measuring tape with an end that doesn't need to be held and as long as tracking is maintained, can measure through walls, floors and ceilings. You can even measure your own height without having to vandalise any door jambs. It doesn't just do the direct distance though. MeasureMint also displays the distance along all the X, Y, and Z axis along the direction you point along when placing your anchor. For good measure it also displays the distance over ground and the height of the anchor above whatever surface is beneath it. You can also lock the measurements in place, add more than one anchor and get the distance between them. MeasureMint is designed to be genuinely useful, flexible and easy to use when you don't have anything better. You'll never have to use your arm or feet to estimate distances ever again! Includes support for both imperial and metric units.

Cliff Timer is a simple and powerful app that lets you measure real-world distances using just a stopwatch and basic physics. By timing how long it takes for an object to fall, you can estimate the height of cliffs and other drops, or measure how far away a storm is by counting the seconds between lightning and thunder. Designed to be easy to use while still based on real equations, Cliff Timer turns quick observations into meaningful measurements, making it perfect for outdoor exploration, learning, or satisfying your curiosity about the world around you. This app uses the formula for height, h=12⋅g⋅t^2, and the formula for lightning, d=t/5. Start the stopwatch, and the app will give you the information.
