Verdict
The clearest difference is in-app purchases: Periodic Timer at none against Hourly Beep's 1. Periodic Timer also leads on ratings volume (167 vs 11) and device support (3 vs 1). Hourly Beep's advantage is rating (4.5 vs 4.1) and update cadence (every 3 weeks vs every 2 months). On price and ads there is nothing between them.
