About

Bump Duo

Read full description

One pregnancy. The two of you. Bump Duo is the pregnancy app for both of you โ€” not her app with a window for you, but one shared place where you both write, decide and feel, as equals. WHAT ONE ADDS, YOU BOTH SEE Tasks, appointments, name ideas, shopping, moments โ€” whatever either of you adds is on both phones the same second. No forwarding, no explaining, no screenshots back and forth. TASKS SOMEONE PICKS UP One shared list instead of calling through the apartment: whoever gets to it first claims it โ€” and the other sees it done, face and all. APPOINTMENTS PREPARED BY BOTH Collect your questions before the appointment, and write down afterward what was said. Whoever couldn't come reads it the same evening anyway. NAMES YOU BOTH LOVE Suggest names as they come to you, and react to each other's. A match only when you've both said yes โ€” until then the app gives nothing away. SHOPPING ON ONE SHARED BUDGET Put the options side by side, vote, and agree โ€” out of one pot you both see. What's bought moves off the list and into the budget. THE CONVERSATIONS THAT KEEP GETTING PUT OFF Guided themes โ€” money, the birth, family, the two of you after the baby โ€” one question at a time. Phone between you, talk it through, write down what's worth keeping. MOMENTS FELT RIGHT AWAY A kick, hiccups, a hard day โ€” share it while it's happening, and feel the answer come back from the other phone. WEEK BY WEEK What's happening this week, with size comparisons you can actually picture โ€” as fruit, an animal or something sweet, photographed rather than drawn. BUMP DUO PRO Every ultrasound photo kept with its appointment, the whole growth curve as one line, every conversation theme, the budget broken down โ€” bought once, on both your phones. And one thing to know: Bump Duo is for keeping track together, not for medical advice. Weeks and sizes are approximations โ€” anything about how yours is going is a question for your doctor or midwife.
