LightSpectrum Pro

This app does not work, gives sane reading what ever the light source ! You should not be charging for an ad pp that doesn’t work.. Rip off…..

It works quite well and accurate. I was buying bulbs for the bathroom and wanted to match the colour temperature of the mirror and the app did a good job.

App shows the exact same colour temperature no matter where is. Inside or out. Tungsten, fluorescent, halogen, LED

Seems pretty accurate for colour balance, and for that reason deserves three stars. However, some of the drop down icons don’t work - not great for a paid app, but it’s pretty cheap. Overall, really useful, but comes with glitches.

The drop downs are sticky and don’t function. Another paid app that’s useless! No stars

I have a calibrated tuneable light at work that I know has a range of 2700-6000K and the app just reads 5000-5100k for the whole range. Doesn’t work at all

Complete waste of Money. Do not download! It doesn't work on my phone 6s. App opens and has a red line through the camera as if it can't access it. Iv tried looking in my settings but cannot get it to work. Awful app

Mine is stuck in the same colour temp and won't connect with the camera. £1.99 headache.

iPhone 5s each time I touch the bottom row of icons it shuts down. No good now!!!

Yep, agree with other reviews. App does not fit iPhone 6+. Interface also pretty clunky. Can't buttons to return from documentation. Or maybe just hidden in the bit I can't see. Shame.
