Why Android ? - because it's the only portable platform that gives
applications ready access to a USB host port - something essential
to being able to use accurate, readily available color measurement
instruments. The fact that it's the largest open platform for mobile
applications, and as well as being available in a wide range of form
factors and price points, adds to its attraction.
Not all Android devices will be able to run ColorMeter, although the
situation is improving all the time with the introduction of newer
Android based products. You need to be running Android version 4.0
(Ice Cream Sandwich) or latter, and your Android device needs a
functional USB on the go (USB OTG) port to connect to most
instruments, or Bluetooth to connect to Blutetooth capable
instruments. Before purchasing
ArgyllPRO ColorMeter or an Android device capable of working with
your instruments, it is highly recommended that you
explore ColorMeter's capabilities, and check that it is going to
work with your hardware, by downloading and running the free
application. See the FAQ below for more information on
choosing an Android device and/or Color measurement Instrument.

By making use of a ChromeCast, ColorMeter can act as
an HDMI Video Test Patch and Test Card source. While the
ChromeCast is not a bit perfect TPG, the use of dithering makes
it accurate to within perceptual limits.
It can be used to display one of six standard Test Cards,
covering Display geometry, Probe locations, Low clipping, High
clipping, Neutrals and Color ramps. It can also be used to
display a test patch color that matches the reference RGB value

For Android devices with a micro USB port, you'll need a USB

2.0 OTG to female Type A) - for any instrument. Simply plug the
instruments normal USB male Type A plug into the OTG lead. Some

They are becoming widely available at stores that sell Phone and
Tablet accessories (e.g. RadioShack seem to stock them [Model:
2604173], Belkin make one [P/N:
F2CU014btBLK ], etc., so
it's worth asking at such a store, and showing them a picture of
one), as well as on-line. (I have had some trouble with one adapter
that has a plug that is slightly too short to reliably plug into my
Make sure that you plug the instrument into the OTG cable,
and then plug the OTG cable into your Android device.
Doing it in the reverse order can often mean that the instrument
won't be recognized.
If your instrument has a detachable USB cable, then it may be more
convenient to use if you can buy a single combined OTG cable to go
from your Android device to your instrument, although these might be
hard to source:
micro-B USB 2.0 OTG to Male B for i1pro2, DTP20 etc.
micro-B USB 2.0 OTG to Male Mini-B - for color Munki
If your Android device has a USB C port, then you will need
a USB C to USB 2.0 female Type A adapter. These are widely available
as accessories for USB C equipped devices. Using USB C, it seems to
be more reliable to plug the OTG cable into your Android device
and then plug the instrument into the Adapter cable.
This is the reverse of the OTG cable!

Q: Will there be an
iPod/iPhone/iPad version ?
A: Unfortunately this is
unlikely, since (as explained above), the ColorMeter application
depends on access to a USB host port on the device, and iOS devices
have neither a USB port, nor are applications allowed to directly
access a USB port using any readily available USB host adapter.
Until Apple changes its policy in this regard, there can be no
version of ColorMeter for iOS. If you think you would find
ColorMeter useful, then the most pragmatic solution at present is to
buy an Android device that will run it. Such devices are becoming
cheaper and more readily available all the time.
Q: Will it run on a BlackBerry
using "Runtime for Android" ?
A: Unfortunately there are
two limitations of Runtime for Android that prevent this from being
possible. One is that it doesn't support USB OTG connectivity. The
other is that it doesn't support Android NDK libraries, and
ColorMeter relies on a native library for its instrument driver
Q: What Android Tablet would you recommend ?
A: I can highly recommend the Nexus 7 (new or second
hand), as it work with all USB instruments and has battery capacity
to power them, as well as a very useful display size while still
being small enough to comfortably hold in one hand.
The Nexus 7 has become hard to get now, and one other 7" device that
I have tested with all the instruments is the Lenovo TAB3 7
Essential. The positives about this tablet is that 1) it works
with all the instruments and 2) it's cheap. Disadvantages are 1)
it's display is lower resolution and has an incorrect aspect ratio
and 2) it's battery performance when sleeping isn't great. Other,
tablets and phones featuring Android V4 and USB OTG support, and
therefore potentially able to run ColorMeter, are also widely
Note that a number of people have reported problems with
using some Samsung models (Galaxy S3, Galaxy Tab 3, Galaxy
Note 2 and others) in combination with the ColorMunki
spectrometer. This may be due to a bug in Samsungs USB host hardware
or driver, and so may depend on which version of Android it is
Here is a list of the Android devices
that existing customers are using, but the safest thing is to try
out a tablet or phone using ColorMeter Demo, to make sure it will
work with your instrument, before you buy it.
Q: What instrument would you recommend ?
A: This very much depends on what you want to measure, and
Q: My i1pro2 doesn't work! - I get an error during
reflective calibration and/or measurement!
- For low cost light level and emissive, ambient and display
color measurement, it's hard to go past the X-Rite
i1 DisplayPro or ColorMunki Display colorimeters.
- For entry level display measurement, the Spyder
4 is another choice.
- To make reflective measurements at the absolute lowest cost
(but with very limited accuracy), the SwatchMate
Cube may be appropriate.
- For a versatile and relatively low cost spectral measurements,
ColorMunki Design or Photo is hard to beat. This
combination is great for graphic arts and photography use.
- A higher end general purpose spectrometer that can be used is
- For high speed and high accuracy display measurement, the Klein
K10-A Colorimeter would be the ideal choice.
- For the most accurate spectral emissive, ambient and display
measurements, then specbos
1211 and 1201 Tele-Spectro-Radiometer is the right
instrument, or a spectraval
1511 or 1501 if ambient measurement is not needed.
A: One of the things many people have noticed about X-Rite's
i1pro2, is that it is very sensitive to the USB lead length and
quality. This is probably an issue with the power being supplied
over USB to the instrument, and X-Rite having made it very
particular about the voltage level. This manifests itself as a
problem whenever the measurement light gets turned on, often during
calibration. The solution is usually to use a shorter (but high
quality) USB lead, say around 1 Meter (3 feet) in length. A short
lead often makes the whole arrangement more convenient to use in a
hand-held configuration anyway. Some Android devices may not be able
to supply sufficient power to the reflective measuring instruments,
or may have a poor USB voltage level, making them unsuitable for use
with the i1pro2.
Q: When I plug an instrument or other USB OTG device in,
nothing happens. How can I fix this ?
A: Either your Android device doesn't support USB OTG, or it
is not enabled. For instance, the Sony Z5 has a "detect usb" button
in the notifications panel that should be turned on.
Q: Is ColorMeter available
in any languages other than English ?
A: At the present time, no.
CGTPL is a small company, and currently does not have the resources
to provide a fully internationalized product.
