Sound Machine App vs Bedside Machine: Which Should You Buy?
You are deciding between a $50–$100 box for the nightstand and an app on the phone already sitting there. Here is what each actually does.
Last updated: July 11, 2026
Short answer: the masking sound is identical, so for most adults a sound machine app wins on price, features, and travel. Buy hardware only if you keep phones out of the bedroom or need a standalone device for a child's room.
What a sound machine actually does
Every sound machine, hardware or app, does one job: it plays steady broadband sound that raises your bedroom's noise floor. Sudden sounds — a door, a car, a snore — have to beat that floor to register in your brain. Raise the floor and they stop waking you. The speaker producing the sound changes nothing about how the masking works.
App vs hardware, feature by feature
| Feature | Bedside machine | DRMN app |
|---|---|---|
| Price | $25–$100+ | Free download; $29.99 lifetime for everything |
| Sound mixing | Rare — one sound at a time | Layer several tracks with per-track volume |
| Timer | Fixed presets, hard stop | Up to 10 hours with gradual fade-out |
| Travel | Another thing to pack and plug in | Already in your pocket, works offline |
| Sound library | 10–30 built-in sounds, never updated | Noise colors, rain, ocean, fan, nature, baby sounds |
| Speaker quality | Consistent, no phone needed | Phone speaker, AirPlay, or any Bluetooth speaker |
When hardware is still the right call
- You keep phones out of the bedroom. If a phone on the nightstand tempts you to scroll, a standalone machine protects the habit.
- A child's room needs its own device. A toddler can't unlock a sound machine and open YouTube. (For nursery setup with a phone kept out of reach, see white noise for babies.)
- You want a night light and sound in one unit. Some nursery machines bundle both.
Everyone else gets more machine from the app.
How to set up your iPhone as a sleep sound machine
- Download Sound Machine Deep Sleep DRMN free from the App Store.
- Pick your base sound. Start with white noise for general masking or brown noise for traffic and snoring.
- Open the mixer and add a second layer if pure noise feels sterile: rain and fan are the usual picks.
- Set volume at conversation level or below, loud enough to blur the noises that wake you.
- Set the timer to 8–10 hours with fade-out, press play, and lock the screen. Playback continues all night.
Frequently asked questions
Is a sound machine app as good as a real sound machine?
For most sleepers, yes. The audio is the same, and the app adds mixing, a fade timer, and offline downloads that hardware rarely offers.
How much does a sound machine cost compared to an app?
Bedside machines run $25 to over $100. DRMN is free to download; the $29.99 lifetime unlock costs less than most mid-range hardware.
Is there a sleep sound machine for adults, not babies?
Yes. DRMN is built for adult sleep first — brown noise, fan hum, rain mixes, and a 10-hour fade timer — and covers the nursery too.
