So far, it has been restricted to professionals, considering the cost, the size and complexity of the equipment. Today, GoSpectro puts the power of spectroscopy in the hands of everyone, offering the world’s most compact and most simple light spectrometers. This application, combined with the GoSpectro accessory, allows to turn any smartphone into a light spectrometer in order to measure, record, analyze and export spectral data.

Verdict
The clearest difference is in-app purchases: GoSpectro at none against Lightscope's 1. GoSpectro also leads on iOS requirement (8.0 vs 17.0). Lightscope's advantage is update cadence (every 5 days vs every 2 months). On price, ads and device support there is nothing between them.
