Verdict
The clearest difference is in-app purchases: Eureka Prometheus User at none against BrewJournal's 2. Eureka Prometheus User also leads on iOS requirement (13.0 vs 15.6). BrewJournal's advantage is update cadence (every 2 days vs every 3 months). On price, ads and device support there is nothing between them.
