OneNest
The modern parenting app.
I'm Chelsea, a mom of three (including 11-month-old twins) in Kalamazoo, MI. Four months ago I had an idea, zero technical skills, and a problem I couldn't stop thinking about.
When my husband and I were expecting, every baby registry app we tried assumed one parent would do all the work. I created the account, added every item, made every decision — he just got sent a link to approve things after the fact. No real ownership, no real involvement.
So I built OneNest: the only baby registry app where both parents get their own login to the same shared registry, with equal ability to add, approve, veto, and decide together.
I learned to build it using AI development tools — no prior coding experience. I worked around naps and bedtimes, hit 22 App Store rejections before finally launching, and somewhere in there also added dedicated onboarding paths for adoptive and surrogacy families, since I realized the same "one person does everything" assumption was baked into nearly every parenting app on the market, not just registries.
Four weeks post-launch, with zero paid marketing:
200+ families using the app

Happy to answer anything about the build process, going from zero coding knowledge to a live app, or the marketing side of getting traction with no budget. 🪺
About
I'm a mom of three, including 11-month-old twins, and I built OneNest because I lived this problem. Every registry app assumes one parent does the work. OneNest fixes that — both parents, one registry.

200 families in four weeks with zero budget is the part people will skim past, but that is the whole signal. You did not build an app, you found a real wedge. Two things I would be thinking about now. First, a baby registry has an expiration date built in: the baby arrives and the job is done. The both-parents, equal-ownership mechanic is much bigger than registries, it is the wedge into shared family logistics, gear, milestones, appointments, the stuff couples keep fighting to coordinate long after the registry closes. The registry gets you the couple at peak coordination pain. The business is everything that comes after. Second, registries are one of the few products with distribution built in: every registry gets shared with dozens of gift-givers, and a lot of them are future parents. Make sure every shared link plants a seed for the next account, not just a gift. You clearly listen to users, so point that same instinct at what they need at month six, not just week one.
The solo-mom angle makes this way more interesting than another “I built an app” story. Curious what was harder: building the product, or figuring out what people actually trusted enough to use?
Huge respect for getting through 22 App Store rejections and still shipping. One thing I’d double down on from the marketing side is turning the “both parents, equal ownership” angle into every onboarding screen and SEO page, because that is a much sharper wedge than “baby registry app.”
Congrats! hats off!!
Congrats on the launch! Building a product while balancing family life is no small achievement. One thing I've learned working with web applications is that security is easiest to address early rather than after growth. Wishing OneNest continued success and a smooth scaling journey!
The interesting part isn't that existing registry apps were missing features.
It's that they may have been making a decision about family behavior without realizing they were making one.
That's what caught my attention here.
