Short app description:

To use SpectaRuler you simply take your measurements with a few heel to toe steps in between. SpectaRuler uses your shoe size to determine both the size of objects, and distance to objects.

SpectaRuler eliminates most of the limitations imposed by other measuring apps. Many Ruler and Range type measuring apps require you to ALREADY know the distance to find the height or ALREADY know the height to find the distance. Some apps require that you place a frame of reference centered in the picture. Almost all of the apps use simple trigonometry that requires the ground be level from you to the object you are measuring.

Key Features (What makes SpectaRuler better?):


Long app description (available on iTunes):

AS FEATURED IN THE "New and Noteworthy" and "What's Hot" Utilities sections!

NOW COMPATIBLE w/ the iPod Touch 4th Generation

"If you have ever found yourself wishing you could know the distance or height of an object or building..SpectaRuler by HollingTech Software LLC can help you."
-Gwen Phua,

"Measurement tool apps … Wouldn't it be great if one actually worked in practice, rather than just in theory? From what I've experienced, SpectaRuler is that app."
-Michelle Schusterman, The iPhone App Review (Scored 9/10)


Here are some of the limitations of OTHER MEASURING APPS:

-Measure height-ONLY if you know distance
-Measure distance-ONLY if you know height
-Measure height and distance-ONLY on level ground
-Measure height or width-ONLY if you are standing at the same height, and directly in front of the object
-Measure height or width-ONLY with a frame of reference in the picture

SpectaRuler is the measuring app that eliminates these limitations!

As long as an object is upright, with SpectaRuler you can measure from higher, lower, the left, and the right!

-Ruler and Range Finder in one app
-Measure upright objects
-Measure small & large objects
-No reference required in pictures
-Measure across uneven surfaces
-Measure objects that are higher or lower
-Measure objects without standing in front of them

PLEASE be sure to follow the instructions.

OK – This all sounds amazing, but how is this possible?

-SpectaRuler uses your shoe size and step count as a frame of reference to measure objects around you.

-Simply take your first measurement(s), take some heel to toe steps, and take your second measurement(s). You choose the # of steps. Typically, more steps take longer, but will reduce measurement uncertainty. Fewer steps will be faster, but will increase measurement uncertainty.

-Since shoes can slightly vary in length, if you notice the measurement results to be slightly too large, try DECREASING the shoe size by 1/2 to 1 size. If you notice the measurements to be too small try increasing shoe size.


1.Set the step count by tapping the STEPS indicator.
2.Hold phone at eye level, tilt to align crosshairs with top of target, and tap screen. If measuring DISTANCE AND HEIGHT keep device at eye-level, and repeat this instruction step for the bottom of the object.
3.Step heel to toe, directly toward target, the indicated number of steps. Make sure after your final step to bring your trailing foot forward (align your toes). Adjust the step count if # of steps taken differs from the on screen indicator.
4.Repeat step 2, and dimensions will slide onto the screen!

1.Set the step count by tapping the STEPS indicator.
2.Align crosshair approximately with the center of the rectangular object you wish to measure and tap screen.
3.Step heel to toe, directly toward target, the indicated number of steps. Make sure after your final step to bring your trailing foot forward (align your toes). Adjust the step count if # of steps taken differs from the STEPS indicator.
4.Repeat step 2.
5.Drag the "X" markers to the four corners of the object you are measuring and tap the check mark. Repeat this process for the second photo, and dimensions will slide onto the screen.

--Note that when measuring DISTANCE AND HEIGHT, or DISTANCE, HEIGHT & WIDTH SpectaRuler will still perform measurements if the ground traversed is uneven or sloping!

--DISTANCE AND ELEVATION is relative to the camera lens. Also, while the object can be above or below, the ground traversed should be flat.
