By Safiye Merve Kolakoglu, from the App StoreDescription by Safiye Merve Kolakoglu Written by the developer, not by AppBrain. Click to read.
Built for people who want relief without the noise: no streaks to perform, no coaches to follow, no quizzes to retake. Just an atmosphere that fits the moment and remembers what worked.
WHAT MAKES CALMSPACE DIFFERENT
Adaptive, not generic. Home tunes itself to your evening: a hero pick chosen for the time of day, a mood-aware atmosphere, and routines you can save and bring back in one tap.
Breath that fits the moment. Six guided patterns calibrated for sleep, focus, or release: the full session runs in-app with ducked audio, an organic breathing visual, and gentle haptics.
Quiet by design. No avatars, no streak pressure, no airport-loud Home screen. Sensory richness instead of decision overload.
SOUNDS, MUSIC & BRAINWAVES
• Nature: rain, thunder, wind, fire, sea, river, birdsong, cat purrs, café ambience
• Noise: white, pink, and brown (fine-tuned for sleep or deep focus)
• Music: meditation, ambient, classical (Bach, Chopin, Mozart, Satie, Schubert), lofi, soft piano, handpan, and more
• Brainwaves: binaural beats, isochronic tones, and Solfeggio frequencies covering delta (sleep), theta (deep meditation), alpha (relax), and beta (focus)
• Curated mixes: Meditation, Sleep, Focus, and Relax scenes, from Japanese Zen Garden to Lucid Dreaming
Mix any sounds together with independent volume controls, save your favorite combinations as your own lists, and let the sleep timer fade everything down at the end.
MEDITATION, YOUR WAY
No scripts, no coach voice. Build the sitting that fits you: a theta brainwave for depth, the meditation music collection, or a mix like Mountain Temple or Sands of Serenity. Open with a breath pattern and set a timer to bring you back.
GUIDED BREATHWORK
• Box Breathing (4-4-4-4): steady focus, balanced energy
• Belly Breathing: slow, deep calm before bed
• 4-7-8 Breathing: calms the nervous system before sleep
• Coherence Breathing (5-5): heart-mind sync, designed for relax mode
• Physiological Sigh: one of the fastest known ways to release stress
• Bhramari (Humming Bee): a soft hum that settles a busy mind
Sessions duck active audio to a whisper, run with a calming visual and optional haptics, then restore your soundscape when you're done.
ROUTINES THAT REMEMBER
Save your favorite combination (breath pattern, sound mix, and timer) as a Routine. Tag it Sleep, Focus, or Relax and it lives on the Yours tab. One tap brings it back, exactly the way you left it.
MOOD-AWARE HOME
Tap Sleep, Focus, or Relax to retune the atmosphere: the hero pick, the breath suggestion, and the visual palette shift to match the mood. Don't tap anything and Home reads the time of day on its own.
THE QUIET DETAILS
• Offline by default: the catalog downloads silently on Wi-Fi so it's there at 2am
• Background playback while you read, write, or drift off
• Sleep timer with smooth fade-out, no abrupt stop
• Localized in 13 languages
• Gentle streaks that encourage, never shame
THE SCIENCE
Calmspace draws on what's known to help: binaural beats for entrainment, Solfeggio frequencies for resonance, nature soundscapes for autonomic reset, and breathwork patterns from clinical and contemplative traditions.
FREE & PREMIUM
The free tier is generous: the adaptive Home, the foundational breathing patterns (Box and Belly), and a meaningful slice of the sound library. Premium unlocks the full catalog, the deeper breathwork (4-7-8, Coherence, Physiological Sigh, and Bhramari), and the richness that turns a habit into a ritual. Monthly and yearly subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period.
