LightSpectrum Pro App Reviews

Complete rip off. Not only doesnt this app work, but the app support button tells me that their website does not work either. Guess the guy that designed my app must have built their website. Where is Mr. Cooks head these days...clearly hes not looking after Apple and its products or reputation!! How can Apple allow a non-functioning app with a non-existent support structure to remain in the App Store. Shame on Apple!!

This is what I get for not reading the reviews before purchasing. App doesnt work on anything newer than the 3GS.

This product simply does not work at all. Apple needs to give refunds and remove it from the store . Too bad because it could be very useful. DO NOT PURCHASE !!!

Save your money. Apple and the developer should pull this app until they can demonstrate that it works.

The developer has produced an unethical way of taking money. Do not buy. Does not work.

the description claims it performs yet most reviews tell the truth, its bogus at least for IP5. I sent an email last November and had a reply that they were working on update fix. Dont waste your $$ until the reviews start to turn positive. I took a chance after reading some reviews that were 3-5 in spite of the overwhelming negative reviews.

Nothing happens on an iPhone 5

Does not work do not buy... Please pull this app from the store

Does nothing on my i5 wont even turn the camera on.

This app is Inoperable on iPhone 5 running iOS 6.0. While it does load and some of the button produce a response, it is unable to access the camera and does not return any color temperature value. After reading other reviews, it seems possible that LightSprectrum does function on some iPhone models running older iOS versions. However, no warning is made in the store description regarding hardware or OS software limitations - so its being misrepresented as a universal app compatible with all hardware and iOS versions. In addition, the developer Website link provided by the Store is broken. I have filed a complaint and asked for a refund. Caveat emptor!

And for $1.99, is a great deal.

The last update allows the app to finally work on my iPhone 5. I cant believe it took as long as it did for an update. The readings are not 100 accurate but its enough to get you in the ballpark for tweaking later... Which is ok. I wish you could set it for florescent to get better readings for that. Sadly, this is the only app (for now) that tries to offer reading color temp of a room in kelvin degrees, so theres not many options to compare it with. Again, be careful trying to read in florescent and incandescent ... But other than that, its worth a few bucks. ...as long as the iPhone 6 doesnt come out and we have to wait another year for this to work.

I really needed an app like this for an upcoming job, but was hesitant based on bad reviews of its past versions. But for just 2 dollars, I figured I didnt have much to lose… Ive now run it on a 3rd gen iPad (Retina), iPhone 4, and iPad mini -- all running iOS 6.1.3. I dont have any way to calibrate its output, but the app runs fine, gives me reasonable results (it "sees" 5500K in daylight, around 3000K for fluorescents, etc.), and seems pretty well behaved. The built-in help is pretty good, but needs to be updated (it mentions a calibration button that the app doesnt seem to actually provide). Id give it five stars, but took off one because the app crashes occasionally -- but then works just fine when I restart it (has only crashed twice, so I cant really characterize whats going on there). So if you were concerned about this apps past reviews, it seems the dev has fixed the major bugs (at least for the devices Ive got available to test it with). A really handy app if youre trying to filter flashes to match ambient light from uncharacterized sources.

Under household tungsten lights at night look at white card provides 5500 Kelvin results. Not accurate.

Great idea but this app was released way too soon. It is wildly inaccurate and doesnt ever give consistent reading. At least if they were consistent, you could calculate the difference. At this point, this app is a complete waste of money. Hopefully they will continue to improve it.

This is a terrific idea. I wanted to use it to think through conversion from incandescent to LED lighting to choose the right color temperature lamps. But the app pretty consistently over estimates the color temperature by a wide margin and it crashes too frequently to be useful. Bid really like my $1.99 back.

This app crashed my phone every time I opened it. Would like to see if it really works.

Direct sunlight 3800k? Nope. Not even close when compared to all temperatures w my color meter.

I was hoping for sources to display as a color temperature reading somewhere in the actual range. Grey cards, bulbs, paper, under daylight shade, or incandescents, or 4100k fluorescents, all show figures I know to be hundreds or thousands of degrees off. It may be that you can set a range to read within, but how useful is it to point at a 6500k source and be shown a 2681k reading?

I had to give this a star to make the review post, but its not even worth that. Completely useless. No matter what light source, always reads 2300 to 2800, completely inaccurate and a total waste of $1.99.
