Why alarm sound fails some sleepers, what vibration, light and distance each add, and how to build a morning that survives a bad night. With named sources and owner reviews.

What Tabata, EMOM, AMRAP and round timers ask of a clock, how digit height decides reading distance, what a 110 dB alert is for, and where our timers fall short.
