Measure anything from 0 to over 2 and 5/8 inches using one of the 4 modes. Even if you work in graphic arts or word processing the micrometer can help, since it will measure point sizes.


Even standing up on a moving bus, it
is easy to set the micrometer to the
smallest scale increment with one
or the increment mode of the SPEED-BAR.


Holding the device in the palm of your hand,
all the controls may be operated with your
thumb without blocking the measurement area
or data box. There is a left and right
micrometer which makes this possible.


This is the most accurate measuring
possible on the iPhone based on 163
pixels per inch.


INCH 0.00 to 2.62 (.01 increments).
FRACTION 0 to 2-5/8 (1/64 increments).
METRIC 0.00 to 6.68 cm (.01cm increments).
POINTS 0 to 189.4 (.1 increments).
points are based on 72 points per inch.


The data window, micrometer barrel and scale
change colors depending on the measurement
mode to instantly recognize which mode
you are using.


The micrometer returns exactly where
you left it.


Measurements are retained when changing
modes. For example if you measured 1 1/2
using the Fraction Mode, selecting the
Inch Mode would would show 1.50. Some
values may change slightly due to the
increment values of the different scales.


All measurements are shown in BOTH
inch and metric values with 6 decimal
places giving accurate conversion values.


Touch anywhere in the SPEED-BAR to
instantly position the micrometer
and then refine the position using the
increment wheel or lift your thumb and


Sliding along the MODE-BAR rotates a large
wheel allowing you to select a mode or the
left or right micrometer. After selection
the color coded icons on the MODE-BAR
shows the mode and micrometer selected,
red for left and green for right like airplane
navigation lights.

Metrology Specialist

I used this Micrometer app to measure a Renishaw Ruby Styli. It helped me identify the correct size (Dia. and Length) to replace for my customer.

This helped when I didn't have a micrometer or caliper handy. I always have my iPhone in my pocket. Now I have a micrometer in my pocket also.

Very cool!

I can't believe there aren't at least a few more comments because this app is great and works well. I didnt know what to expect due to the lack of reviews but i took a chance and i gotta say im impressed. Definitely worth it IMO

Great Application!

I have my $350 set of Mitutoyo digital calipers and micrometer next to me comparing the measurements. My goodness, KUDOS this this group because this app is accurate to .01, dead on!

If you need to measure within hundreths of an inch accurately get this. WAY WORTH THE MONEY.

This is a cool app!
