The clearest difference is rating: SySight at 5.0 against LightSpectrum Pro's 4.1. SySight also leads on review sentiment (66% vs 28%) and update cadence (every 5 weeks vs every 3 months). LightSpectrum Pro's advantage is ratings volume (39 vs 2) and chart position (#113 vs unranked). On ads, in-app purchases, monetization model and device support there is nothing between them.

LightSpectrum Pro costs $1.99 and SySight $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
