Store description excerpt
"When did I fall asleep last night?" — NightDial answers the moment you open it. It reads the sleep data your Apple Watch or iPhone already saves to Health, and draws each night as an arc on a 24-hour dial. Zero input required. Just sleep like you always do. ■ Sleep Rings Sleep that crosses midnight stays whole on a circle. Bedtime to wake-up, one arc, one glance. ■ A calendar of rings One ring per day, a month at a time. Aligned arcs mean a steady rhythm — the messy nights stand out instantly. ■ Sleep Score Duration, rhythm, continuity, and timing — scored every morning, with the full breakdown visible. You'll know exactly what to fix. ■ Today's Note One piece of advice a day, picked for your recent sleep pattern from thousands of pre-written insights. ■ Night Vitals (Apple Watch) Heart rate, respiratory rate, blood oxygen and more, shown alongside each night. ■ Social Jet Lag See exactly how far your weekends drift from your weekdays — in minutes. Now you know why Mondays hurt. ■ Privacy Your sleep data is processed entirely on your device and never leaves it. ―――――――――― NightDial Plus (subscription) ―――――――――― The free version fully covers your last 14 days, plus today's score and advice.
