Tones for sleep, focus and calm: 15 presets, or your own pitch and beat, for headphones or a speaker. Four noise colours and nine soundscapes, such as rain, ocean, fire and forest. Pro mixes three sounds and saves your mixes. A sleep timer that fades the sound out, and playback that keeps going with the screen locked. Twelve colour themes. Free plays any two at once; Pro opens the rest.
Frequencies, noise and soundscapes for sleep, focus and calm.
Resonia plays tones, coloured noise and soundscapes, on their own or mixed together, for sleep, focus and calm. Pick a preset such as Night (432 Hz with a 3 Hz beat), add brown noise, set the sleep timer and put the phone down. Every sound comes from the phone itself: the tones and noise colours are synthesised live, and the soundscapes are real field recordings, looped and stored on the phone. Nothing streams and nothing downloads. FREE FOREVER • Four presets: Night, Focus, Calm and Still • 432 Hz and 528 Hz pitches, 3 Hz, 7.83 Hz and 40 Hz beats, binaural (headphones) or isochronic (speaker) • Four noise colours: white, pink, brown and green • Two soundscapes: rain and ocean • Any two sounds at once • Sleep timer with a gentle fade-out: 15 minutes to 2 hours, until a morning time you set, or until you stop it • Keeps playing in the background, with lock screen controls • Three colour themes PRO, ONE-TIME PURCHASE • All 15 presets, every pitch and beat, and any pitch or beat you set yourself • Singing bowl and soft pad timbres alongside the pure tone • All nine soundscapes: rain, ocean, wind, stream, fire, fan, night air, forest and chimes • Mix up to three sounds, at most one of them a tone, each at its own volume, and save the mixes you like • Nine more colour themes No subscription, no renewals, nothing to cancel. Pay once and it's yours. HOW IT WORKS Pitches are labelled by their frequency, beats by their frequency and band, nothing more. Binaural beats need headphones: each ear hears a slightly different pitch, and the beat is the pulse you perceive between the two. Isochronic beats pulse a single tone, so they work through a speaker as well. CALM BY DESIGN A warm, dark screen by default, made for dim rooms, with a single accent colour. No reminders, no account, no ads, no analytics. The app collects nothing, and your purchase is handled by Google Play. Resonia is available in English, Ukrainian, German, Spanish, French, Polish and Portuguese. Questions or ideas? support@kalaganov.dev
