LIVING BINAURAL BEATS Sonibral is a living binaural beats engine created by a composer, built for sleep, meditation, focus, and creative flow. Unlike conventional binaural beats that rely on simple, repetitive tones, Sonibral creates a rich field of evolving binaural overtones, continuously generated and shaped in real time. Explore original instrumental music composed specifically for Sonibral, and blend it with carefully curated natural soundscapes, including ocean waves, wind, rainfall, birdsong, and flowing water. When music is playing, the binaural synth becomes part of the composition itself, forming an evolving tonal foundation while remaining adjustable as you listen. MAKE IT YOUR OWN - Choose between Sleep, Meditate, Flow, and Focus. - Combine original music with natural soundscapes, or listen to the binaural engine on its own. - Explore Ambient Mode, transforming music and soundscapes with slower playback, reverse movement, and spacious reverb. - Customize binaural patterns, overtones, frequency ranges, and soundscape textures. - Discover unexpected combinations with the randomizer and save your favorites as presets. - Set a timer and let Sonibral play while you rest, work, or unwind. ALWAYS EVOLVING Sonibral's synthesis engine runs live on your device. Its tones, overtones, and textures move continuously, never repeating in quite the same way. Move a control and you can hear the engine glide, shift, and reshape itself without stopping. Change states, music, or soundscapes without interrupting the experience. That is what living binaural beats means. FREE TO EXPLORE Enjoy unlimited free 7-minute sessions. Premium unlocks custom timers and unlimited session lengths for $3/month. Headphones are recommended for the full binaural experience. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is ads: Chillax at none against Sonibral's shown. Chillax also leads on ratings volume (10 vs 1) and iOS requirement (13.0 vs 17.5). Sonibral's advantage is update cadence (weekly vs every 2 months). On price, rating, in-app purchases and device support there is nothing between them.
