Verdict
The clearest difference is review sentiment: Interesting Engineering at 67% against Phys.org's 18%. Interesting Engineering also leads on rating (4.7 vs 2.8) and update cadence (every 10 days vs every 5 weeks). Phys.org's advantage is ads (none vs shown) and device support (3 vs 1). On price, ratings volume, in-app purchases and monetization model there is nothing between them.
