Most sleep apps hand you a playlist. Calma hands you a mixer. Layer steady rain over deep brown noise, drop a ceiling fan underneath, set the volume of every layer separately, and fall asleep to a sound that is actually yours. Then save it and start the same thing tomorrow with one tap. WHY CALMA IS DIFFERENT • A real mixer — up to 6 layers at once, each with its own volume slider. • One-time purchase. No subscription, no renewals, no "trial ending" emails. • Fully offline. Every sound ships inside the app: no streaming, no data use, works in airplane mode. 193 SOUNDS White, pink and brown noise. Steady rain, heavy rainstorms and distant thunder. Ocean, forest streams and wind through trees. Campfires and fireplaces. Ceiling fans, washing machines, hair dryers and vacuum hum. Trains, ticking clocks and quiet rooms. Crickets, birds and night breeze. Soft piano and tuning frequencies (174, 396, 432 and 528 Hz). A TIMER THAT DOESN'T WAKE YOU Set it and forget it. Calma fades the whole mix down gradually instead of cutting the sound off, so the silence arrives before you notice it. BRAINWAVE LAB Binaural beats running alongside the mixer — move the slider to pick your frequency and layer it under rain or noise. Smart Descent walks the beat down to 2 Hz (Delta) over 20 minutes for a hands-off transition into sleep. Headphones recommended. BREATHE FIRST A two-minute breathing animation, including 4-7-8, to slow your body down before the mix even starts. FOR BABIES AND TODDLERS White noise, womb sounds, heartbeat, lullaby music box, hair dryer, washer and calm car-ride hum, all in one category. FREE AND PRO Free, with no time limit: 55 sounds, 3 layers at once, 5 saved mixes, the sleep timer and the breathing exercise. PRO unlocks all 193 sounds, 6 simultaneous layers, 25 saved mixes, Smart Descent and the full Brainwave Lab range — for a single payment, forever. Sleep well. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Calma PRO Lifetime | $14.99 | one-time | | Calma PRO Lifetime Launch | $12.99 | one-time | ## Version history (last 5 releases) ### 1.1.0.22 — 2026-08-26 • Night Sky is twice as big — 12 chapters and 36 constellations to uncover, up from 6 and 18. • Look back through every constellation you have already completed, chapter by chapter. • Constellation and chapter names are now translated in every supported language. • More reliable purchase restore and clearer connection error messages. • Better timing for in-app messages, so nothing interrupts a running session. • Stability fixes across the mixer. ### 1.0.5.21 — 2026-07-23 • More reliable purchase restore and clearer handling of connection errors. • Better timing for in-app messages, so nothing interrupts a running session. • Stability fixes across the mixer. ### 1.0.4.19 — 2026-05-08 This update includes new constellations, refreshed app icons, improved iOS release metadata, and several stability fixes across audio playback, notifications, and Quiet Pages. ### 1.0.3.17 — 2026-04-27 Added support for new languages!
