AR Ruler & Tape Measure App is a free mobile utility app developed by HoangSi. It is a measuring tool that can help users determine the length, height, or distance of an object using their smartphone or tablet camera. It achieves this by utilizing Augmented Reality (AR) technologies for advanced image mapping to extract desired measurements. 

Virtual measuring tape 

As its name suggests, you can think of AR Ruler & Tape Measure App as a virtual measuring tape in addition to being a ruler and even a protractor for gauging angles on flat surfaces. Speaking of even planes, there’s also a spirit level meter, which will come in handy in construction work. 

All data will be saved and recorded for future reference, and there’s even a built-in calculator for quick calculations without leaving the app. Now, despite its rich feature set, you still need to be wary of margins of error. Think of it as a companion to your physical tools, which can supplement them for less demanding and precise needs. 

Nice to have 

If you work in a profession that requires a lot of measuring, or if you just don’t have them on hand, the AR Ruler & Tape Measure App is a handy supplementary tool that you can use in a jiffy in place of their physical counterparts. Keep in mind, though, that this is not for precision work but more for casual use.
