Once the app is dialled in, Smart Measure even beats Google’s own AR measurement app in terms of speed and ease of distance measurement. In fact, it is best to spend a few minutes referring to the comprehensive calibration guide on the official blog for best results. The app assumes the height of the user to be 5 foot 9 inches by default, so it’s best to manually calibrate it if you’re taller or shorter. That means measurements will be wildly inaccurate if you use the app while you’re seated or if you otherwise aren’t in the same horizontal plane as the object that is being measured. Since this app relies on the Pythagorean Theorem, the phone has to be at the correct height for optimal measurement accuracy.
Having tested the app thoroughly and validated its measurements with a good old-fashioned measuring tape, it’s safe to say that most of these negative reviews are down to user errors and calibration oversight. The apparent simplicity of this process is also the reason for the odd reviews with negative ratings complaining about inaccuracy.
The app is developed by a Korean Android whiz by the handle of Android Boy, who seems to have a knack for programming fairly accurate smartphone-measurement tools. Smart MeasureĪ part of a larger suite of smartphone measurement apps, Smart Measure is a widely-used and even more widely-acclaimed distance measurement tools.
In other words, while one of our recommendations is good for intermediate distances since it relies elementary trigonometry, you might want to use another one of our recommendations leveraging perspective estimation for longer distances.Īlso read: How to Calibrate Your Android’s Sensors for Better Performance 1. Furthermore, since smartphones aren’t specialized measurement tools, they utilize a number of sensor arrays to estimate distances. We recommend installing all three apps because each one of these is suited for different distance-measurement scenarios. Luckily for you, we have waded knee deep through the mediocrity of the Google Play Store to bring you three of the best distance-measurement apps for Android. Unfortunately, for every distance-measurement app that is barely competent, there are a dozen that are virtually useless. A smartphone is now all you need to quickly tackle macro measurement tasks such as estimating networking/electrical cable runs within the house or figuring out how far your daily jogging route takes you.
