By using iPhone or iPad camera, you can measure a spectral intensity of the light by a spectrum image from a spectrometer. Press camera > photo button to shoot a spectrum image dispersed by the spectrometer. If reflected light is observed, please be the in the area of ​​the dark rectangle on the upper side of the camera screen. For iPadOS 13, open the Control Center and then tap the "Lock Orientation" button to avoid rotating the spectrum capture area. Press the graph button to show the light intensity distribution of the spectrum calculated by the camera image. The values ​​of R, G and B are respectively calculated as the average value of the central quarter width of the spectral image. Adjust the intensity of the input light by, for example, narrowing the slit so that each color does not exceed the maximum value 255. The value of R+G+B is also plotted in black. You can change the plot scale of spectral intensity by <> button. By pressing the plot button, sliding the upper spectral image to the left and right, and entering two points with known wavelengths, you can plot the wavelength scale. If the R0 wavelength is set as reflected light (0 nm) and the R1 wavelength is set only for the first time, the wavelength scale is plotted only by setting the R0 wavelength after the second time. You can save the plot with wavelength scale as image. For the data to be stored, a filter was applied so as to smoothly connect the intensity curves of the sensitivity wavelength regions of R, G and B colors. Because it is very dangerous, please never see strong light such as the sun, and please do not put it in the iPhone's camera.

This app is capable of efficient analysis of quantum dots emitting in the visible spectrum and near-UV. Using a DIY iPhone case glued to a spectroscope this spectra analysis tool costs about $10. There is no raw data output (but please add this feature!). The graphs are comprehensive and easy to use and the app is intuitive and stable. Overall the best spectroscope app for basic and general analysis, with the addition of raw CSV data or something, this can be a very powerful and efficient scientific tool. Cheers!

I would very much like to use this but there are no instructions. Even something on your app page would make this much much better.
