I love this tool alot! This is the only application available for this purpose! But, two things. I would like it to tell the specific frequency and wavelength of the Infared Radiation (IR) that I'm trying to messure since cameras are usually able to take in IR. I'm not the biggest fan of it saying "IR or Red 700-800 Nanometers (nm)". And lastly, after the first time I use this, It will start forcing me to buy the subscription thing in order to use it which bothers me.

Thanks a lot for your review! I also wish that it was possible to distinguish between different wavelengths in the Near IR range. The smartphone cameras see these wavelengths, but they all appear the same to it, so it is unfortunately not possible for an app to tell them apart. Yes, it is free for a few weeks. Thank you!

Like this app for my curiosity. Using it for free. Skipped the subscription. My current need isn't great enough to subscribe or buy.

Thanks for the kind words, Paul! Glad curiosity is being satisfied. Please write to me if I can improve the app in some way or if any questions pop up. Thank you!

Such a cool app! I downloaded it to test the wavelength validity of a cheap red light therapy device. Didn't read ahead enough to see that my phone camera would sell me short. It was accurate for the orange light wavelengths but the rest were out of range.

Thank you for the great review! You're right that phone camera sensors have limitations with certain wavelengths. Glad it worked well for the orange light. Thanks for testing it out and for your support!

works good for some light. However, if your wanting below 475nm (what I wanted it for) is almost useless. it just tells you it's below 475. This is a hardware limitation, but wish I was warned before starting the trial. I guess I should have read more carefully, it may be in there somewhere. Edited

Yes, it is true. Please note that this is not a limitation of the app, but a limitation of how your mobile phone and its camera is working. Thanks a lot for your understanding and review!

well I tried it on a couple devices. seem to work pretty good devices were well short of the expected frequency of light. I like the app was easy to use. I used a white background and shine the light into that.
