2Lines

Track your cycle, predict ovulation, and follow every week of pregnancy — all in one beautifully designed app. Record heartbeats, log symptoms, and lasting keepsakes.

Our Story:

2Lines was born out of a real need. When my wife and I started trying to conceive, we found ourselves juggling half a dozen apps — one for cycle tracking, another for BBT charting, a separate one for pregnancy week-by-week updates, yet another to time contractions, and a notes app to keep track of doctor visits and questions. None of them talked to each other, and none of them captured the full picture.

We wanted one place — a single pane of glass — to capture every detail of the journey from the first hopeful cycle all the way through to holding our baby. Every temperature reading, every heartbeat recording, every ultrasound photo, every nervous question before a doctor's appointment. All of it, together, in one beautiful timeline.

So I built it. What started as a side project for our family became 2Lines — named for those two little lines on a pregnancy test that change everything. We hope it helps your family the way it helped ours.

WHETHER YOU'RE TRYING OR EXPECTING 2Lines adapts to where you are. Start in Trying to Conceive mode with smart ovulation prediction powered by your cycle history, BBT charting, LH test logging, and cervical mucus tracking. When you see those two lines, transition seamlessly into pregnancy mode — your data carries forward.

WEEK-BY-WEEK PREGNANCY TRACKING Every week from 4 to 40, see exactly what's happening: baby's size compared to familiar objects, developmental milestones, how your body is changing, and a curated tip. A progress ring counts down to your due date while a trimester indicator shows how far you've come.

CAPTURE WHAT MATTERS MOST Record your baby's heartbeat at every appointment. Photograph ultrasounds and belly progression. Log milestones with dates, notes, and emoji. Every moment is automatically organized on your timeline and tagged to the right week.

SMART CALENDAR INTEGRATION Your home screen shows a live calendar that syncs with Apple Calendar. Doctor visits, due dates, and personal events appear together so nothing falls through the cracks. Add appointments from inside the app and they show up everywhere.
