Weekend sleep looks different? Compare the nights before explaining them.

Weekend nights may differ from weekdays in bedtime, wake time, room noise, travel, alcohol, meals, exercise, stress, phone position, and how long the recording ran. A different morning feeling or app value does not identify which factor mattered.

SomniSense observes phone audio. It does not measure circadian timing, sleep stages, oxygen, airflow, or why one morning felt better or worse.

Compare the groups in a way you can repeat

• Separate weekday and weekend nights only if the labels match a question you actually have.
• Check recording coverage and phone placement before comparing values.
• Keep multiple overlapping changes visible instead of crediting one convenient explanation.
• Repeat the observation across several comparable weeks.

What a difference can mean

A repeated group difference can be a useful prompt to observe again. It is not proof that sleeping later, drinking, position, or another routine caused the acoustic change.

If tiredness persists or affects safety and daily function, use the symptom itself—not a consumer threshold—as the reason to seek professional guidance.
