Do you need a light meter? Try an app for your mobile before you buy

Photometer Pro is simple to use, looks like an antique light meter, but works fine. It measures both reflected and incoming light with your iPhone.

For Android phones there is a similar app called Beecam, which also have a better user interface.

The accuracy of measurements depends on the sensor in your mobile.

We tested Photometer Pro and it worked well with an iPhone 5.
