About

Dawnlog

Features
Read full description

Dawnlog is a morning sleep diary. Each morning you answer a few short questions about last night: when you got into bed, when you tried to sleep, how long it took, how often you woke up, when you woke for good, when you got up, and how you rate your sleep quality. Most mornings it takes about fifteen seconds. Over days and weeks the diary shows what your nights really look like: time in bed, total sleep, how long you lay awake, and how these change. A daily reminder keeps the habit going, and with Dawnlog Pro the Home Screen widget lets you log last night in one tap. When you have an appointment, Dawnlog Pro turns any period of up to four weeks into a clean PDF report with the averages and charts a doctor or sleep specialist expects from a sleep diary. FREE, FOREVER • Morning entry with unlimited history • Overview, averages and chart • Daily reminder • CSV export of every night you logged, from Settings • A sample report, so you can see the PDF before you buy DAWNLOG PRO — ONE-TIME PURCHASE, NO SUBSCRIPTION • PDF report for your doctor, any period up to four weeks, as often as you like • Extra fields: naps, medication, caffeine • Home Screen widget, with an option to hide the numbers PRIVATE BY DESIGN • No account, no sign-in, no server of ours • No ads, no analytics, no third-party SDKs • Your diary is stored on your iPhone and in your own device backup; nothing is sent to us • Delete everything at any time from Settings Dawnlog is a personal diary. It is not a medical device and does not diagnose, treat, or give health advice. Values are calculated only from what you entered. For interpretation and health decisions, talk to your doctor.
