Verdict

The call

The clearest difference is monetization model: PrismScope at free against Predator Clock's paid. PrismScope also leads on rating (4.8 vs 4.6) and review sentiment (90% vs 79%). Predator Clock's advantage is update cadence (every 2 months vs every 15 months) and ratings volume (61 vs 5). On price, ads, in-app purchases and device support there is nothing between them.
