Verdict
The clearest difference is price: flameeye at Free against LightSpectrum Pro's $1.99. flameeye also leads on rating (5.0 vs 4.1) and update cadence (every 3 weeks vs every 3 months). LightSpectrum Pro's advantage is ratings volume (39 vs 1) and chart position (#104 vs unranked). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.
