PREMIUM ā PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase. A private sleep diary you fill in yourself ā no watch, no microphone, no HealthKit. Log last night in under a minute and let the patterns surface on their own. Every auto-tracker guesses. SleepTrack asks. You record what actually happened ā when you got into bed, when you got up, how often you woke, how you felt ā and it turns those honest entries into sleep debt, efficiency and bedtime consistency you can act on. It is the same manual method clinical sleep diaries have used for decades, wrapped in a calm, dark interface made for bleary morning eyes. WHAT YOU GET ⢠Last night on one card the moment you open the app ā hours slept, quality stars, times you woke ⢠A one-minute morning log: bedtime, wake time, awakenings, minutes awake, quality, restedness, dream notes ⢠12 factor tags ā caffeine, alcohol, screens, exercise, stress, reading, meditation and more ā correlated against your quality so you see what actually moves it ⢠Sleep debt counted nightly against your own goal and summed by week, so "I'll catch up on the weekend" becomes a number ⢠Bedtime consistency plotted night by night ā the tighter the cluster, the steadier the routine ⢠A doctor/clinic report ā your whole diary as a clean summary or CSV, ready to hand to a professional PERFECT FOR ⢠Anyone who wants to track sleep without buying a wearable ⢠People working through insomnia who have been told to keep a sleep diary ⢠Side sleepers, stomach sleepers, watch-haters ā anyone who will not wear a device to bed ⢠Shift workers and new parents trying to find a pattern in the chaos WHY NOT JUST USE AN AUTO-TRACKER? Auto-trackers need a device on your wrist or a phone on your mattress, and they still guess. A diary records what you know to be true ā and writing it down each morning is itself the habit sleep clinics recommend first. Two taps of honesty beat a night of estimated motion data. PRIVATE BY DEFAULT Every night you log stays in a local database on your iPhone. No account, no cloud, no microphone, no motion sensing ā nothing leaves the device unless you export a report yourself. PREMIUM (PURCHASE REQUIRED) SleepTrack Premium unlocks the complete Insights tab (duration and quality trends, factor correlation, weekly sleep debt, bedtime consistency), your full diary history, the doctor/clinic report export, and a custom reminder time. Choose a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase. Log tonight's sleep tomorrow morning ā your first patterns appear within a week. SleepTrack is a personal journal, not a medical device. For ongoing sleep problems, talk to your doctor.

Verdict
The clearest difference is in-app purchases: RestLog at none against Sleep Diary's 3. RestLog also leads on iOS requirement (15.1 vs 17.0). Sleep Diary's advantage is ads (none vs shown). On price and device support there is nothing between them.
