Astra: Sleep & Focus

Astra App Space

About this app

Turn sounds into your own universe.

Astra is a space-inspired ambient sound app for sleep, focus, study, and relaxation.

Instead of choosing sounds from a simple list, Astra turns each sound into a planet. Build your own universe, arrange your planets, and create an atmosphere that feels uniquely yours.

CREATE YOUR UNIVERSE

Build a personalized soundscape by adding planets to your universe. Each planet represents a different ambient sound, from rain and piano to cosmic winds, storms, thunder, and dreamy night sounds.

MIX SLEEP & FOCUS SOUNDS

Combine multiple ambient sounds and shape your atmosphere exactly how you like it. Add, remove, and arrange planets around your star to create your perfect mix.

SLEEP, FOCUS, STUDY, OR RELAX

Create an atmosphere for whatever you're doing:

• Listen to calming sleep sounds at night
• Stay focused while studying or working
• Create ambient background sounds for reading
• Relax with peaceful soundscapes
• Build a calming atmosphere for meditation

KEEP LISTENING

Astra can continue playing while your screen is turned off or while you use other apps, so your universe doesn't have to stop when your screen does.

YOUR UNIVERSE. YOUR SOUND.

There is no single perfect soundscape. Mix your favorite sounds and build one that feels right for you.

Explore the stars. Create your universe. Find your atmosphere.
