Features

Everything you need for better sleep

A focused toolkit — score every night, wake gently, and keep your data where it belongs.

HealthKit Integration

Driftly reads and writes sleep sessions and related metrics through Apple HealthKit, so your sleep data lives where your other health data already lives — under your control.

Smart Alarm

Wakes you at the lightest point of your sleep cycle inside a gentle window, so you start the day feeling rested instead of jolted awake.

Sleep Score & Insights

Every morning Driftly translates the night into a clear sleep score with trends, event detection, and plain-language insights you can actually act on.

Goals & Achievements

Set consistency goals, build streaks, and earn milestone badges that keep you motivated to protect your sleep night after night.

How it works

Set it once. Sleep better from tonight.

Three steps from unboxing to your first sleep score.

Place your iPhone

Set Driftly on your nightstand and grant microphone + HealthKit access. The app tunes itself to your room.

2

Sleep through the night

Driftly listens on-device, scores every stage, and detects snoring or disturbances as you rest.

3

Wake gently, know more

The Smart Alarm finds your lightest moment, and you wake up to a clear nightly score and insights.

Nightly Sleep Score

One number, the whole picture

Every morning Driftly distills the night into a single 0–100 score built from duration, depth, disturbances, and consistency — so you can feel your week get better at a glance.

  • Trends, not spikes — track 7-day and 30-day averages
  • Understand what pulled the score down, in plain language
  • Spot your best nights and replicate the routine
Smart Alarm

Wake at the lightest moment

Tell Driftly the latest time you need to be up. It monitors your sleep stages and triggers the wake sequence inside a gentle window — so you never get yanked out of deep sleep again.

  • Personalized wake window per night
  • Falls back to your latest time if you stay in deep sleep
  • Plays through your iPhone or Apple Watch
HealthKit at the core

Your data, where it already lives

Driftly reads and writes sleep sessions through Apple HealthKit, so your sleep history stays under your iOS privacy controls — alongside heart rate, HRV, and the rest of your health story.

  • One source of truth for sleep + recovery
  • No separate cloud account required
  • Works on iPhone and Apple Watch
Designed for trust

Built for the way you actually sleep

Privacy, insight, and a gentle wake — all on your iPhone.

Built around your privacy

Your most personal data never leaves the phone

Audio is processed on-device to classify sounds like snoring and talking. Nothing is uploaded, and nothing is shared with Driftly or anyone else.

  • No cloud account required
  • Delete a session, and it's gone from the device
  • Revoke permissions any time in iOS Settings
Gentle, actionable insights

Trends you can actually act on

Driftly turns the night into plain-language insights, so you know what to do tonight — not just what happened last night.

  • Consistency and bedtime stability
  • Disturbance breakdowns with context
  • Weekly recap of what worked
