Most white noise apps loop a recording, so you hear a seam every time it restarts (even when "seamless"). Many also come with ads, subscriptions, and tracking. The White Noise Generator creates its sound live on your iPhone, so there is no loop. Slide from white to pink to brown noise, then soften the tone until it sounds like a fan in the next room. The sleep timer fades out gently, and it keeps playing in the background. No ads, no account, no subscription, no data collected. Free and 1.2 MB.
