Sleep Tracker App for Simple, Focused, Hassle-free Sleep Tracking SleepSimple sleep tracker is a sleep tracking app designed to track your sleep duration starting from when you sleep and when you wake up. Instead of estimating sleep using motion or sound, SleepSimple sleep tracker app measures sleep duration using real time you control, giving you dependable data you can review long term. There are no wearables required, no background monitoring, and no accounts to manage. Open SleepSimple sleep tracker app before bed, tap once, and stop it when you wake up. Sleep duration is calculated instantly and stored in your history. This approach keeps sleep tracking simple while avoiding inaccurate automatic detection. Track sleep and naps accurately SleepSimple sleep tracker logs the essential information you actually need: • Bed time and wake time • Total sleep duration • Nap duration • Sleep and nap counts • Complete chronological sleep history If you forget to log a night, entries can be added or edited later without breaking statistics. Each session may also include optional notes so you can remember unusual nights, interruptions, or schedule changes. Understand patterns over time SleepSimple sleep tracker analyzes your sleep data and summarizes it in a clear format: • Daily, weekly, monthly and yearly averages • Total sleep time across any period • Custom date-range summaries • Sleep frequency and consistency • Simple sleep quality score based on your target duration Bar charts visualize changes over time without overwhelming detail, making it possible to understand trends even after months or years of use. Practical sleep insights SleepSimple sleep tracker provides helpful observations derived from your real sleep history. For example, SleepSimple sleep tracker detects when you have slept less than your normal duration multiple times in a row or when your schedule becomes inconsistent. These insights are intentionally simple and interpretable. SleepSimple sleep tracker does not attempt to predict sleep stages or make medical claims — it highlights patterns so you can make your own adjustments. Fully private and offline SleepSimple sleep tracker works entirely on your device. • No sign-in • No cloud storage • No personal data collection • No behavioral tracking Your sleep history remains under your control at all times. SleepSimple sleep tracker also allows you to export your data whenever you want to keep a personal backup or analyze it elsewhere. Home screen widget Start or stop sleep tracking directly from your home screen and immediately see your most recent sleep duration without opening SleepSimple sleep tracker. Built for long-term reliability Many sleep apps focus on automation, sensors, or subscriptions. SleepSimple sleep tracker instead focuses on stability and clarity. Because entries are based on your actual times, your records remain consistent across years of use. SleepSimple sleep tracker is suitable for anyone who: • prefers manual accuracy over automatic guesses • wants a lightweight sleep tracker • does not use a wearable device • wants permanent, readable sleep history • values privacy and offline storage Sleep tracking should help you understand your habits, not create noise. SleepSimple sleep tracker keeps the process predictable so your sleep data stays meaningful over time.

Sleep Diary

PREMIUM — 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 — 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 — when you got into bed, when you got up, how often you woke, how you felt — 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 — 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 — caffeine, alcohol, screens, exercise, stress, reading, meditation and more — 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 — the tighter the cluster, the steadier the routine • A doctor/clinic report — 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 — 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 — 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 — 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 — your first patterns appear within a week. SleepTrack is a personal journal, not a medical device. For ongoing sleep problems, talk to your doctor.
