SleepDrift

Drift into better sleep with a calm, beautifully simple sleep tracker built for nightly use.
Every morning takes seconds: log when you went to bed, when you woke up, and how you felt. The app does the math — even when you fall asleep before midnight and wake the next day — and turns each night into clear, useful insight you can actually act on.
🌙 WHAT YOU CAN DO
• Log a night in under 10 seconds with quick date chips, smooth time pickers, and one-tap emoji quality ratings
• See last night at a glance on a deep-night gradient card showing duration, bedtime → wake time, and quality
• Track your weekly average and how many nights you have logged
• Browse full history grouped by week, each entry with a colored duration bar matched to your quality rating
• Swipe any entry to delete it instantly
• Switch between Week and Month statistics with a single tap
• Read a custom bar chart that draws every night's duration alongside your personal sleep goal as a dashed reference line
• Watch your averages update live: average duration, average bedtime, average wake time
• See your quality distribution across all 5 levels with colored bars
🏷️ TAGS THAT REVEAL PATTERNS
Tag each night with the things that may have affected your sleep:
☕ Caffeine • 🍷 Alcohol • 💪 Exercise • 📱 Screen time • 😰 Stress
Over time, the patterns become impossible to ignore.
😴 QUALITY YOU FEEL, NOT NUMBERS YOU GUESS
Rate every night with one of five expressive emoji — from 😩 to ✨. No tracking bands, no microphones, no ambiguous scores. Just an honest pulse on how rested you actually feel, every morning.
🎯 SLEEP GOAL & REMINDERS
Set your personal sleep goal anywhere from 5 to 12 hours. The bar chart automatically draws your goal as a dashed line so you can see exactly which nights hit it.
Turn on the bedtime reminder and a gentle notification will arrive every evening at the time you choose — perfect for finally going to bed when you said you would. The reminder reschedules itself automatically so it keeps firing day after day.
🌗 DESIGNED FOR NIGHT
A deep-indigo dark theme is on by default — easy on tired eyes during a 2 AM log. Prefer a brighter look? Switch to light or follow your system theme any time.
📊 PRIVATE, OFFLINE, YOURS
Every entry stays on your device. No accounts. No cloud sync. No ads. No tracking. Just your sleep, in your hands.
✨ DETAILS THAT MATTER
• Built with Material 3 and Jetpack Compose for fluid, modern motion
• Indigo and violet palette inspired by a clear night sky
• Color-coded quality at every glance — green for excellent, amber for okay, red for rough
• Custom-drawn Canvas charts that scale to your goal and your data
• Bottom navigation with four clear sections: Home 😴, History 📅, Stats 📊, Settings ⚙️
• Empty states that invite you in instead of feeling broken
• Friendly handling of midnight: a 23:00 bedtime and 07:00 wake correctly counts as 8 hours, not negative
WHO IT IS FOR
• Anyone who wants to understand their sleep without strapping a sensor to their wrist
• People rebuilding their sleep schedule after travel, shift work, or a rough season
• Anyone curious whether late caffeine, that glass of wine, or extra screen time really makes a difference
• Parents, students, athletes, remote workers, night owls trying to drift earlier
START TONIGHT
Open the app, set a goal, flip on the reminder, and log your first night tomorrow morning. Within a week you will see the shape of your sleep. Within a month you will see exactly what to change.
Sleep better, one night at a time. 🌙✨
