The app

@parents_on_tiktok exclusive · The parent's stethoscope

At 2 a.m. someone is going to ask you: do we go in? Don't guess. Record it.

Press one button. Capture about 30 seconds of your baby's real heart and breathing sound, then send it to your pediatrician as a link they just press play on. The Skeeper does not decide anything. It makes sure the person who does decide is hearing what you heard, instead of you trying to describe a cough over the phone in the dark.

$499one-time, app included, ships free

One "just to be safe" ER visit runs $500 to $1,500, and a lot of them end with a shrug and a discharge paper. The SM-300 costs less than one of those nights, and it makes every scary night after it an informed one. It will never tell you to skip the doctor, and it will never tell you it is safe to stay home. It makes sure that when you call, you have the sound in hand.

One device, three modes

Heart. Lung. Fetal.

One 53-gram disc captures three kinds of sound, so you can hear it, save it, and share it with the person who can help.

Heart mode

Capture the heartbeat

Place the disc on the chest and record the heart sound in clear, high-fidelity audio. Hear it clearly, save it to the app, and share the recording with your doctor.

Lung mode

Record the breathing

Capture the sound of your child's breathing when a cough or wheeze has you wondering. Record about 30 seconds and share the actual sound with your pediatrician instead of describing it.

Listens only. Emits nothing.

Fetal mode

Listen, and only listen

Fetal mode is a passive microphone. It only listens to naturally occurring sound and emits nothing. It is not an ultrasound. Capture the moment, save it, and share it with your OB.

For the ones still waiting

About the fetal mode, plainly.

If your OB told you not to buy a consumer fetal doppler, they were giving you good advice, and this is not one. So here is the difference, stated plainly, because this is the part people get wrong.

Fetal mode is a passive microphone. It emits nothing. No ultrasound, no energy of any kind into your body. It only listens to sound that is already there, the same way a stethoscope on your OB's neck does.

What it is not: it is not a monitor, it is not a substitute for a single prenatal appointment, and it is not there to tell you your baby is fine. No home device can tell you that, and you should walk away from any that says it can. It is there so you are allowed to listen, and so that when something is worth mentioning, you can hand your OB the recording instead of a description.

The 2 a.m. protocol

Four steps, one button, about 30 seconds.

This is the whole thing. Learn it once now, so you are not learning it at 2 a.m. with a screaming baby and a phone in your hand.

Put it on the chest

The app shows you exactly where to place the disc, front and back. You do not need to know anything about anatomy to get a clean recording.

Press record

About 30 seconds. The Skeeper Pro app captures the sound and shows the waveform live, so you can see it is picking something up.

Listen back

Play it in clear, high-fidelity audio as many times as you want. You are hearing what a stethoscope hears, not what a phone mic across the room hears.

Send it to the doctor

Share it as a secure link straight from the app. It plays in any web browser. No portal, no login, no software on their end. They press play and hear exactly what you heard.

That is the job, start to finish. You are not diagnosing anything and neither is the device. You are removing the part where the most important information in the room is a sound that nobody but you ever heard.

Why it is different

A baby monitor tells you a number. Skeeper captures the sound.

Most home baby devices watch a single vital sign around the clock and alarm through the night. Skeeper is different: you use it in the moment, then share what you captured.

	Typical baby monitor	Skeeper SM-300
How you use it	Runs continuously all night	Episodic, use it in the moment
What it captures	A single number or a video feed	The actual heart, lung and breathing sound
Doctor-shareable	Trends, not the sound	Share the recording by secure link
Alarms at night	Beeps and alerts	Non-alarm, it does not beep all night
Works across life stages	Infants only	Heart, lung and fetal modes
What it costs over time	A device, plus a required app plan, often	One price. App included.
Who makes sense of it	You, alone, staring at a number	Your own pediatrician, listening to the real sound

Think of it as a complement, not a replacement. An oxygen monitor measures a number. Skeeper captures the actual sound, the thing that number can never tell you, and lets you share it. They do completely different jobs. And because it is one price with the app included, you are not signing up for a second bill just to keep using it.

One device, everybody under your roof

It does not stop at the baby.

You will buy this for one small person. It works on every other person in the house too, which is most of why it earns its price.

Your partner

Heart and lung modes work on adults exactly the same way. Same disc, same 30 seconds, same shareable recording.

Your older kids

The croupy one at four in the morning, the one whose cough has been hanging around for two weeks. Capture it while it is happening, not at the appointment three days later when it has stopped.

Your parents

The cough your dad keeps waving off at Sunday dinner. Record it, and let him take the actual sound to his own doctor.

You

Yours is the chest you have never once listened to. It takes 30 seconds and the recording is yours to keep.

Same rule for all of them: the Skeeper records and shares. It does not interpret, and it does not replace anyone's doctor.

What people are saying

From the field to the family.

“

I have used real gear in the back of a helicopter. This is the first consumer device I would actually keep in my own home. It captures the sound cleanly and it is simple enough that anyone can use it.

★★★★★

My toddler had a cough that sounded different one night. I recorded about 30 seconds and sent it to our pediatrician in the morning. Having the actual sound to share made the whole conversation easier.

★★★★★

I already have a baby monitor for oxygen, but this is the piece I was missing. Being able to hear and save the breathing sound, then share it, gave me something concrete to bring to the appointment.

Renee M.

Mom of an asthmatic child · representative example

★★★★★

As a second-time mom I wanted to hear my baby between OB visits without a fetal doppler. Knowing this is a passive microphone and not an ultrasound is exactly why I chose it. Simple and reassuring.

Questions, answered

Good questions. Straight answers.

Will it tell me whether to go to the ER?

No, and you should be suspicious of anything that claims it will. The Skeeper records sound and lets you share it. That decision stays where it belongs, between you and a clinician. What changes is that you get to make the call with the actual sound in hand instead of a memory of it, and your doctor gets to hear it instead of hearing you try to describe it. If you think it is an emergency, it is an emergency. Call 911.

My wife handles all the doctor stuff. Is this actually for me?

That is most of the reason it exists. When the scary moment happens, the person holding the baby is whoever is closest, and at 2 a.m. that is often you. Thirty seconds of recording is a job you can do without knowing anything clinical, and it is genuinely useful to the person who does the appointments. You are not taking over. You are showing up with something in your hands.

Is it FDA-approved?

The Skeeper SM-300 is FDA-cleared, not FDA-approved. The two terms mean different things. "Cleared" means the FDA reviewed the device and found it substantially equivalent to a legally marketed device, which is the common pathway for consumer medical devices like this one. "Approved" is a separate, higher-bar pathway used for higher-risk products. Devices in this category, including popular home health devices, are cleared rather than approved.

Does it diagnose anything?

No. Skeeper does not diagnose. It records and captures the sound so you can hear it and share it with your doctor. The interpretation stays with your clinician. Think of it as a way to bring your doctor better information, not a replacement for their judgment.

Is the fetal mode safe? Is it an ultrasound?

Fetal mode is a passive acoustic microphone. It only listens to naturally occurring sound and emits nothing into the body. It is not an ultrasound and does not work like the consumer fetal dopplers you may have read about. It sits in the same acoustic-listening category as a stethoscope.

Is it HSA/FSA eligible?

It may be eligible. Eligibility depends on your specific plan, and some plans may ask for a Letter of Medical Necessity. Check with your plan administrator before you buy so you know how your account treats it.

Will my pediatrician accept the recordings?

A clean recording gives your doctor better information than a phone video or a spoken description of a cough. You share it as a plain audio link that plays in any browser, so there is no portal or software on their end. Every practice is different in how it uses outside recordings, so that part is up to your doctor.

The parent's stethoscope

Have it before the night you need it.

A consumer FDA-cleared 3-in-1 smart stethoscope. Heart, lung and fetal modes in one 53-gram disc, smaller than a cookie. Nobody has ever ordered one of these at 2 a.m. and had it arrive in time.
