Calma: Mix sounds. Sleep better. No subscription.

Hey Product Hunt 👋 I’m Mat, the solo maker behind Calma. I built Calma because I wanted a sleep app that felt calm, personal and useful — without forcing another monthly subscription. Calma lets you mix up to six sounds, including rain, nature, white noise, brown noise, pink noise and ambient audio. You can fine-tune each layer and save your favorite soundscapes for sleep, focus or relaxation. It also includes brainwave sessions, guided breathing and a small Night Sky Ritual that rewards consistency over time. No account is required, and the full version can be unlocked with a one-time purchase. I’d love to hear your honest feedback — especially on the mixer, onboarding and whether the app feels simple enough for a nightly routine.
