Verdict
The clearest difference is review sentiment: Caffeinated Vitals at 100% against AlterMe's 64%. Caffeinated Vitals also leads on rating (5.0 vs 4.7) and monetization model (free vs ad-supported). AlterMe's advantage is ratings volume (1.5K vs 1) and update cadence (every 4 days vs fortnightly). On price, ads and in-app purchases there is nothing between them.
