XL-500 portable BLE spectrometer device is required. Please visit https://nanolambda.myshopify.com/ for more details. XL-500 is an ultra compact Bluetooth Spectroradiometer based on disruptive digital-nano convergence technology. While its size is compact, the features and performance is comparable to conventional industry popular equipment. It is easy and convenient to use as a portable device with smartphone app, as a spectrum recorder with internal memory and rechargeable battery. XL-500 is individually calibrated and provides device-to-device repeatability. This app supports: 1) Emission measurement (SPD, PPFD, LUX, CRI, CCT, CIEXYZ, CIExy, CIEuv ) 2) Periodic measurement (as spectrum recorder) 3) Reflection measurement (relative-SPD, CIEXYZ, CIELab, CIExy, CIEuv) Start the nanoLambda's latest BLE spectrometer adventure now.
OSpectrometer
This app uses your device's camera and screen to perform basic optical spectroscopy. Analyze the visible light spectrum of objects, map light wavelengths to RGB values, and save or share your findings. It functions offline without external hardware.
- Visible light spectrum analysis
- RGB color value mapping
- Wavelength selection and scanning
- Front camera reflection sensing
- Save and share results
- Offline functionality

Optical spectroscopy in the visible light spectrum is a commonly used tool in different fields such as health, manufacturing, art, and forensic research. OSpectrometer implements basic spectrometer functions using the built-in camera and screen without requiring external devices or programs. - Visible light spectrum is transformed and mapped to a function that generates RGB (Red Green Blue) color values - A specific light wavelength can be selected and used to illuminate a desired target (i.e., close to the screen) - The whole spectrum or a specific part of the spectrum can be selected and scanned - Front camera is used to sense the reflection from the target object - Consistent and repeatable reflection/absorption amplitude with respect to the color spectrum - The result can be saved and shared - Works offline, no need to connect to any network or internet Privacy-policy: https://software.nanorescenter.com/osprectrometer-privacy-policy Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: NSP32 nanoLambda Spectrometer at none against OSpectrometer's 2. NSP32 nanoLambda Spectrometer also leads on iOS requirement (13.0 vs 15.1). OSpectrometer's advantage is update cadence (every 2 weeks vs every 2 months). On price, ads and device support there is nothing between them.
