Verdict
The clearest difference is rating: Prod.Timer at 5.0 against LightSpectrum Pro's 4.1. Prod.Timer also leads on update cadence (every 3 weeks vs every 3 months) and price ($0.99 vs $1.99). LightSpectrum Pro's advantage is ratings volume (39 vs 1) and chart position (#59 vs unranked). On ads, in-app purchases and device support there is nothing between them.
