Do you need a white noise machine, or an app?

The short answer · Machine vs app · A baby room · Travel · Try it free
The short answer: a white noise machine and a good app do the same core job - a steady, even sound that masks disruptions so you sleep. A machine is a dedicated box you never think about; an app turns the phone you already own into one, with more sounds, mixes and a sleep timer, usually free. For most people an app covers it; a dedicated machine still makes sense in a few cases.
What a white noise machine gives you
A white noise machine is a small device whose only job is to make sound. You set it once and forget it - no phone in the room, one button, always in the same place. The trade-offs: it costs money, usually plays only one or a few sounds, is another thing to pack and power, and many models use a small built-in speaker.
What an app gives you
An app turns the phone you already own into a sound machine - and adds every noise color (brown, white, pink and more), the ability to mix and save your own blends, and a drift-off timer that fades the sound as you fall asleep. It travels in your pocket and is usually free to start. The trade-off is that it uses your phone, and some people prefer to keep the phone out of the bedroom.
You want zero phones in a baby room, an always-on box you never touch, or a device the whole household shares.
You want more than one sound, you travel, you want a sleep timer and custom mixes, or you would rather not buy a single-purpose gadget.
For a baby room
Parents often choose a machine so there is no phone by the crib - but an app on a spare phone or tablet does the same thing for free. Whichever you use, keep the volume moderate and the source a sensible distance from the crib.
For travel
A machine is one more thing to pack and plug in. An app is already on your phone and works offline - on a plane, in a hotel, at a relative house - so your child sleep sound comes with you.

Frequently asked
Both work. Parents who prefer no phone near the crib often choose a machine; an app on a spare phone or tablet does the same job for free. Either way, keep the volume moderate and the source a sensible distance from the crib.
For most people, yes. An app plays the same steady masking sound all night, adds more sound options and a sleep timer, and costs nothing to try. A dedicated machine mainly wins if you want a phone-free, always-on box.
A steady, even sound helps many people sleep by masking sudden noises - snoring, traffic, a creaking house - so the brain stops reacting to each one. The effect comes from the masking, not the specific device, so a machine and an app work the same way.
