ambient

Have you ever listened to ambient sounds like ocean waves so many times that you memorized them and started thinking, “That sound comes next…”? ambient combines rain, wind, waves, campfires, trains, distant thunder, and more to create soundscapes that keep shifting little by little. Even the same waves or campfire play with different patterns and pitches each time, so you never memorize the order of the sounds. Birds, insects, water drops, and other accents also appear at random, ensuring that the exact same pattern never repeats. Use it before sleep, while focusing, or whenever you want to rest quietly. No ads. Just install the app and press Play to begin. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://dotpx.com/en/privacy_policy.html

Verdict
The clearest difference is in-app purchases: トゥドリ at none against ambient's 2. トゥドリ also leads on update cadence (every 2 days vs fortnightly). ambient's advantage is device support (6 vs 3). On price, ads and iOS requirement there is nothing between them.
