BumpSync

Pregnancy apps are built for one person

Having a baby is a two-person job. The apps aren’t. The partner hears everything second-hand, and the real decisions (the name, the pram, who does the night feed) end up in WhatsApp.

Names got couples in

Picking a name is the one decision every couple enjoys arguing about. Each parent swipes on their own phone. Only the names you both like show up.

Couples stayed. Solo users didn’t.

A month after sign-up, 37% of connected couples were still using BumpSync. Solo users: 4%. Fewer than a third ever invited their partner.

That changed the roadmap. More features wouldn’t fix retention. Getting the second parent in would.

So 2.0 was built around the partner

• Invite during setup, tracked as its own funnel. It used to sit in settings.
• A weekly email and nudges timed to the week of pregnancy.
• Shared baby tracking after the birth: feeds, sleep, nappies and growth. Your partner sees the 3am feed without asking.
• Products inside the prep lists, where the decision is made, not on a separate offers page.

What live users broke

• 7 of 32 invited partners were being dropped into new-user setup. Caught by a performance review, reproduced with a scripted QA run, fixed.
• An early “lift” turned out to be iOS users on the old build. Every analytics event now carries the app version.
• A parent said the bedtime suggestion ignored the last nap. Now it doesn’t.
