Verdict
The clearest difference is price: Negentropy at Free against KLAC's $1.99. Negentropy also leads on rating (5.0 vs 4.5) and review sentiment (100% vs 75%). KLAC's advantage is update cadence (every 10 days vs every 21 months) and ratings volume (141 vs 2). On ads, in-app purchases, monetization model and device support there is nothing between them.
