Drift turns the real ocean into sound you can feel. Using live data from NOAA ocean buoys around the world, Drift generates ambient soundscapes that shift and evolve in real time. Wave height, swell period, wind speed, and water temperature shape layered audio through studio-grade DSP synthesis. Every moment is unique. Whether you're working, meditating, sleeping, or just decompressing, Drift gives you a living connection to the sea. How it works: - Select any buoy within the NOAA network - Drift maps the buoy's real-time measurements to audio parameters using custom signal processing. - As ocean conditions change, your soundscape changes with them. A calm day in Monterey sounds nothing like a winter storm off the Oregon coast. Features: - Live NOAA buoy data driving real-time generative audio - Choose from buoy stations across both US and Canada coastlines - Layered ocean, rain, and wind synthesis - Studio-grade DSP engine built for rich, immersive sound - Designed for focus, sleep, relaxation, and deep listening The ocean is always moving. Now you can hear it. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://drift.naturaltech.io/privacy

Verdict
The clearest difference is rating: Drift at 5.0 against Biorhythmmm's 4.3. Drift also leads on update cadence (weekly vs every 2 months) and ratings volume (17 vs 3). Biorhythmmm's advantage is in-app purchases (none vs 4) and iOS requirement (15.0 vs 17.0). On price, review sentiment, ads and monetization model there is nothing between them.
