RulerPhone is an interesting idea with some utility, but I just don’t see any reason to spend $2.99 on this app. RulerPhone is neat to use for a while, but once you’ve measured almost everything in the room with varying success, it quickly becomes another app in your list that you probably won’t use often. So why only 20 minutes? Once that time elapsed, so did the novelty. When I didn’t, RulerPhone would be off by as much as three feet in some cases and proved useless when I wanted to measure the dimensions of less linear objects like a chair. Generally speaking, it did well and came within a few centimeters as long as I followed the instructions perfectly. I used RulerPhone for about 20 minutes, measuring things all over the house to see how well it performed. It uses touch screen as a ruler or tape measure to make quick measurements, to split. That said, the measurements are more accurate the closer the credit card is to the center of the image and if you’re looking to make three-dimensional measurements, you’re out of luck - it only supports two-dimensions. Millimeter Pro is a easy to use and helpful measurement tool for iPhone or iPad. The actual measurements are displayed above the image.Īs long as you use a credit card and align the blue card over it perfectly, you shouldn’t have too much trouble measuring accurately with RulerPhone. As soon as the two cards are aligned, you click “Measure” and a ruler is displayed, which you can move around and extend to measure the distance between objects in the picture or their length. After that, you snap the picture and move to the next screen, which asks you to align a blue card that’s displayed so it lines up perfectly with the credit card in the picture. In order to start measuring, you need to place an object about the size of a credit card in the picture you’re about to take in order to derive accurate measurements between the objects in the image. Once you start RulerPhone up, it explains how to use the app. Here’s the deal: you can download RulerPhone for $2.99 in the App Store if you want to measure distances of up to 12 feet or you can pick up RulerPhone Lite for free if you don’t need distances longer than 1.5 feet. ![]() The app is called RulerPhone and its premise is simple: it will let you take a picture with your iPhone and allow you to measure the distances and dimensions between objects in that picture. You can copy them on apps, save them on Notes, or send them on Mail.I came across an interesting app in the App Store today that’s worth a look. This feature is helpful when you need to measure a series of objects. Measurement HistoryĪside from guides and Ruler View, you can also access your previous measurements and screenshots you took during that measurement session by tapping on the list button in the upper left of the screen. If you use an iPhone, youll find plenty of ruler apps available as well. Adjust the handwriting area: Drag the resize handle (on the left) up or down. Change color or tools: Use the Markup tools. This feature makes it a lot easier to measure objects than tapping and moving your device around manually. Tap, then draw or write with your finger. You can simply tap the plus button ( +) anywhere on the guide to start measuring. The sensor detects edges and shows guides to help you measure them. ![]() Guidesĭevices with LiDAR will show additional vertical and horizontal guides as you measure objects. You simply need to move your device closer to the measurement to see the ruler overlay over the line measurement, where the object’s dimension can be seen in granular increments. Ruler ViewĪside from the usual measurement features, devices with LiDAR also have a Ruler View that can be accessed when you zoom in on a measurement. E - Bottom bar: View available Layer actions (add, hide, clear, delete layers, etc), and Layer properties (blend, opacity, etc). D - Layer preview - Toggles the layer stack on/off. C - All layer actions: Displays a list of all the layer actions. If you wish to repeat the measurement, just focus the device elsewhere to reset the measurement. B - Key layer actions: Tap on a layer twice to access a pop up menu of highly used layer actions.
