Build a standalone bedside alarm with a loud speaker, battery backup, and configurable dismissal challenges such as mental arithmetic, pattern recall, or scanning a physical tag placed across the room. The device should provide a clearly marked emergency override with a deliberate delay and keep only the current alarm active to prevent challenge stacking. The initial product can be sold directly to deep sleepers, shift workers, students, and households seeking a dependable alternative to app-based challenge alarms.

The signals span several years and multiple products, showing durable demand for challenge-based waking alongside persistent phone operating-system reliability problems. Reviews as recent as 2026 still report missed alarms and recommend maintaining a separate backup alarm.
