What It Does

Twonest tracks a pregnancy, but not for one person. Both partners join the same journey inside one app: the same week, the same milestones, each seeing the view that matters for their role.

Why We Built It

Pregnancy apps are overwhelmingly built for one user: the mother. But a pregnancy is lived by two people. Partners who want to be involved get a second-class experience, forwarded screenshots, second-hand updates, apps clearly not designed for them.

We watched friends live this. The mother tracked everything; the father found out what was happening when she remembered to mention it. Not because he didn't care, because the software gave him no place to participate.

Hence the name: two nests. One pregnancy, one shared home, two people in it.

The Build

React Native, one shared data model with role-aware views. The design rule: every feature must make sense for both roles, or it doesn't ship. The kick counter is the mother's tool, but the partner sees the count and the trend. The appointment calendar belongs to both.

Technical Notes

  • Cross-platform from day one, couples don't choose matching phones
  • Offline-first: the app must work in a hospital basement
  • Gentle notifications: supportive, never anxious, this app talks to people in a sensitive season of life, and every push notification is written accordingly

Current State

Available on Google Play and the App Store, actively maintained.
