Driftly: Sleep & Focus Sounds

Driftly is not a medical device and does not diagnose, treat, cure, or prevent any sleep condition. Please consult a healthcare professional for medical sleep concerns.

Driftly is the sleep sound app that learns what you need tonight — and gets better every night.

Most sleep apps overwhelm you with hundreds of sounds and ask you to figure out the mix. Driftly does the opposite. A 60-second sleep quiz maps you to one of five sleep archetypes (Racing Mind, Light Sleeper, Anxious Parent, Tired Professional, Restless). Then AI personalization handcrafts your nightscape — a curated mix of nature, ambient, and breathing sounds tuned to your archetype, your sleep history, and your morning ratings.

One tap to sleep. The next morning, rate your night with a simple 1-to-5 swipe. Driftly's closed-loop AI engine adjusts tonight's mix based on what worked yesterday. Night 1 is good. Night 14 is dialed in.

WHAT YOU GET

• Personalized nightscapes — the 1-tap mix that matches your archetype tonight
• 50 sounds across 6 categories — Rain, Forest, Ocean, Brown Noise, Ambient, Cozy
• 8 guided breathing exercises — 4-7-8, Box, Heart Coherence, Deep Belly, Progressive, Countdown, Grounding, Morning Energy
• 12 sleep stories — narrated journeys for nights when sounds aren't enough
• Sound mixer — layer up to 5 sounds with per-layer volume; save your custom mix
• Sleep timer with gradual fade-out — 15, 30, 45, 60 minutes; never wakes you up
• Background playback + lock-screen controls — pause, skip, or adjust without unlocking
• Sleep calendar — see your last 30 nights at a glance with rating-tinted dots
• AI insights — Driftly tells you what's working ("You sleep best with Brown Noise on Sundays")
• Bedtime reminder — pick your time, weekday/weekend split, OS-aware notifications
• 4 swappable themes — Forest Night (default), plus 3 more dark-first palettes
• Dark by design — no white screens at 2 AM

HOW DRIFTLY GETS BETTER EVERY NIGHT

Most sleep apps are static. Driftly learns. The first night uses a rule-based mix from your sleep quiz. Nights 2 through 14 use Thompson Sampling — a Bayesian recommendation algorithm — to explore what works for you. By night 15, your mix is converged on the sounds that actually help you fall asleep. The science is real; the experience is one tap.
