Once you have taken your two photos, you can begin taking measurements by indicating whether you want to measure width or height, and then dragging along the parts of the photo you want to measure. As with Photo Measures, a magnifying glass appears to help ensure accuracy. Once you have completed this process on both photos, the app generates a measurement.

I found that the measurements were surprisingly accurate, within a few tenths of an inch in most cases, provided the device was calibrated correctly. That said, if you need absolutely precise measurements, it probably wouldn’t hurt to measure the old-fashioned way as well.

Additionally, you can use the app to enter in your own measurements the same way you can with Photo Measures. But this feature lacked much of the functionality afforded by Photo Measures. For instance, you can’t import photos from your camera roll—you must take all of the photos from within the app. While this makes sense for measuring purposes, I found it frustrating when it came to simply recording measurements you already have. Also, your customization options are far more limited in Measured. Unlike Photo Measures, there is no way to record a note, and the app has no support for recording or measuring angles (though you can specify whether the measurement is of size, distance, or elevation). Measured can only share photos via email or to your Camera roll, so it lacks the export options available in Photo Measures.

Despite these shortcomings, Measured’s ability to accurately measure dimensions on-the-go make it a handy utility . Measured is compatible with the iPhone, iPad, and fourth-generation iPod touch running iOS 4.3 or later.
