It depends on what you want. BetterSleep has the most powerful sound mixer for building custom blends; myNoise offers the most precise, frequency-level control; White Noise Lite and Rain Rain are the simplest; Dark Noise is great for iOS automation. Try a couple of free tiers first.
“Meditation apps” and “sleep-sound apps” get lumped together, but they're really different tools. Meditation apps sell guided sessions and stories; sleep-sound apps are about ambient audio — white noise, rain, fans, nature — that you set and forget. If what you want is a good sound to fall asleep to, these are the apps built for exactly that.

Two things that matter more than the app
Whatever you pick, look for seamless looping (no obvious pop where the track repeats) and a fade-out timer so the sound eases off rather than cutting out abruptly. And keep the volume low — roughly the level of a quiet refrigerator is plenty to mask disturbances without troubling your ears through the night.
The best sleep-sound app is the one whose sound you stop noticing. Try a couple of free tiers before paying for anything.
Evidence tier: Promising. Steady background sound genuinely helps many people sleep by masking disruptions; the research is supportive but mixed. Pick by feel. How we rate evidence →
