Verdict
McMaster and Olight both sit at 4.3 stars, but that hides the real split: 68% of McMaster's written reviews are positive against 28% of Olight's. McMaster also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). Olight's advantage is update cadence (every 11 days vs every 5 weeks). On price, rating, in-app purchases and device support there is nothing between them.
