• No account registration
• No data collection
• Works entirely offline

SLEEP TIMER & FALLING ASLEEP Smooth audio fade-out, smart screen dimming, and haptic feedback help you fall asleep quickly and naturally:

• Precise fade-out duration (audio gradually fades to zero without jolting you awake).
• Haptic pattern support (e.g., an "Inhale/Exhale" rhythm to help slow your heart rate).
• Automatic playback stop to save battery life.

GENTLE WAKE-UP (ALARM) Forget harsh and startling alarms. Sleep Timer wakes you up as comfortably as possible:

• First — a gradually increasing vibration (from rare pulses to frequent ones).
• Then — your chosen ambient sound, with volume rising from 0% to 100% over a custom duration.
• Works independently of the sleep timer (you can set both night and morning modes simultaneously).

MASSIVE LIBRARY & MIXES Create your perfect acoustic environment. Combine up to 3 sounds into your ideal mix with individual volume controls:

• Classic noises (white, brown, radio static).
• Nature sounds (rain on a tent, ocean waves, forest, melting snow, night crickets).
• Cozy home textures (fireplace, fan, cat purring, brewing coffee).
• City and travel (train rhythm, night city noise, airplane cabin).

FULL-SCREEN BACKGROUNDS & COLOR THERAPY Your phone turns into a window overlooking the rain or the night sky:

• Full-screen live backgrounds that won't blind you in the dark (Dunes, Night Sea, Starry Sky).
• Warm color filters to block blue light.
• Customizable smooth screen dimming synchronized with the audio fade-out.

SCENARIOS & SCIENTIFIC APPROACH

• Save your favorite timer and sound combinations for a quick start.
• Use built-in, research-based presets (e.g., "Resonance Breathing" to lower heart rate variability, or a 25-minute "Power Nap" to avoid sleep inertia).

PRIVACY BY DESIGN All your settings, mixes, and scenarios are stored exclusively locally on your device. Sleep Timer does not send audio data to a server, has no built-in trackers, and does not share information with third parties.

IMPORTANT Sleep Timer is a tool for relaxation and acoustic environment control. The app is not a medical device. If you suffer from chronic insomnia, sleep apnea, or other serious sleep disorders, please consult a doctor.
