Verdict

The call

The clearest difference is ratings volume: HiCoffee at 839 against Decaf AI's 8. HiCoffee also leads on update cadence (every 10 days vs every 6 weeks) and device support (5 vs 2). Decaf AI's advantage is review sentiment (100% vs 82%) and rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.
