Verdict

The call

The clearest difference is in-app purchases: AO at none against RANDOM.ORG's 6. AO also leads on rating (5.0 vs 4.6) and update cadence (every 3 weeks vs every 3 months). RANDOM.ORG's advantage is ratings volume (1.3K vs 3) and iOS requirement (15.0 vs 26.5). On price, ads, monetization model and device support there is nothing between them.
