Parents, in their own words. It works.
“I bought the car seat because my baby brain has been difficult to live with post birth. It is really well made, stands out as a quality product.”
KimVerified customer
“I have been looking for something like this specifically just in case, especially after this summer and us having so much heat. It works really well, we have had a couple of false alarms to all the family but better safe than sorry.”
JuneVerified customer
“With all the access to new tech, it makes complete sense to invest money in safeguarding our newborn.”
TylerVerified customer
“I was surprised how low profile the seat is. Comfortable and minimalist, and does exactly what it says it does. I always keep the keyring on me because I am terrible for leaving my phone in the car and that worries me, good failsafe.”
AnitaVerified customer
“Better safe, never sorry.”
JoanVerified customer
“Whether I or my wife are out in the car with Skyler, we have a little bit of peace of mind just knowing that she is okay. The GPS thing is world class, honestly, that is the difference between this and the cheap clip things that you have to fit every time anyways.”
KaydenVerified customer
“Being a first time parent your whole way of life changes not just your routine, why would you not buy something like this, not like it breaks the bank for child safety.”
SteveVerified customer
A note from the founder
I wrote this as a new dad, not as a company.
When our first baby arrived, I read everything and lay awake listening. Every shelf was monitors for the cot. For the back seat, where a small child spends part of every week out of sight and asleep, there was almost nothing.
And I knew I was capable of driving to work on a Saturday. Everyone is. So we built something that does not rely on my memory.
That is all I wanted as a father. Nobody was selling it, so we made it.
Founder, BabiSit
What we will never tell you
Four things we are not going to say to you.
- We will never tell you this prevents anything.
- We will never tell you it replaces you.
- We will never tell you it catches everything.
- And we are never going to frighten you into buying.
Need to know more?
Why we built it, and what it will never do.
The research behind the product, the technology named, and the honest list of what it does not do. All on one page.
Questions parents ask
The two hardest questions, answered first.
What if my phone is on silent?
The alert overrides silent, vibrates and lights the screen. If you still do not respond, it goes to the next person on your relay, with the location.
What if it gets it wrong?
Sometimes it will. Every sensor gives the odd false alert. A false alert means you check and everything is fine. We would rather that than the alternative.
What if I don’t hear it at all?
That is what BabiRelay™ is for. After the time you set, it shares the car’s location with the family you chose. Whoever is closest gets there.
Can we both see Babi Angel’s readings?
Yes. The app pairs to two phones. If a reading drifts outside the range you set, it lets you know so you can go and look.
