OpenAlarm is the alarm clock for mornings when a normal alarm is too easy to silence. Build alarms around the way you actually wake up: • Require one or more disarm challenges: Math, Memory, Steps, Shake, or Scan • Set a snooze budget so snoozing eventually stops being an option • Enable a wake-up check that asks whether you are still awake a few minutes later • Schedule repeating weekday and weekend alarms • Skip or move one occurrence without changing the repeating schedule • Start nap countdowns and pause or extend them • Control active naps from the Lock Screen and Dynamic Island OpenAlarm uses Apple’s alarm system so scheduled alarms remain dependable. Your alarms and settings stay on your device. There are no accounts, ads, analytics, or tracking. OpenAlarm is free and open source.

Verdict
The clearest difference is in-app purchases: OpenAlarm at none against Clock's 2. OpenAlarm also leads on ads (none vs shown) and update cadence (every 8 days vs every 2 months). Clock's advantage is rating (3.4 vs 3.0) and device support (3 vs 1). On price and ratings volume there is nothing between them.
