About

BellyNote

Features
Read full description

Count down to your due date, follow your pregnancy week by week, and keep the small moments you want to remember. BellyNote brings your pregnancy calendar, kick counter, journal, personal sound recordings and new birth-preparation tools together on your iPhone. YOUR WEEK & DUE-DATE COUNTDOWN See your estimated pregnancy week, explore 40 weeks of development and size comparisons, and count down to your due date. Pick a future date in the calendar to see your estimated week and day. Use a known due date or estimate one from your last period and cycle length, conception date, or IVF transfer date and embryo age. Add a countdown widget on supported Home and Lock Screens. Dates and development are general estimates. Your maternity care team can confirm or revise your due date. CONTRACTION TIMING Tap to start and end a contraction, review duration and the interval between starts, and revisit saved sessions. On supported iPhones, an active session can appear as a Live Activity when enabled. This is a manual timing tool, not a diagnosis or an instruction about when to go to hospital. Follow your own maternity care team's advice. Contact them if you are concerned. A SIMPLE KICK COUNTER Tap when you feel a movement. Review the count and session duration, undo an accidental tap, add a note and save the session to your story. The counter records movements you enter. It does not detect movement automatically or assess your baby's health. A completed count is not a medical result. A LITTLE FAMILY FUN Try the traditional Chinese gender chart and share a playful family card, or make a reveal card for a sex you already know. The chart is a game, not a scientific prediction, scan or medical result. YOUR PREGNANCY JOURNAL Write a short note, use a prompt when you need one, and revisit entries alongside movement sessions and personal sound memories, organized by pregnancy week. Filter your story and search your notes. PERSONAL SOUND MEMORIES Record with your iPhone microphone, see a live waveform, replay saved recordings, edit titles and add notes. Export or share only the recordings you choose. Connect headphones for live audio monitoring. Recording results vary by device, surroundings, microphone placement and stage of pregnancy. The app cannot confirm the source of a sound or a fetal heartbeat. PRIVATE MOMENTS Your personal records are stored on your device. You choose what to export or share. Optional reminders and widgets help you return to your daily moment. IMPORTANT BellyNote is a personal pregnancy journal, manual counter and sound keepsake app. It is not a medical device, fetal Doppler, monitor or diagnostic tool and does not provide medical advice. Contact a qualified healthcare professional with questions or concerns. Available in English, German, Spanish, Turkish, Japanese, Korean, Italian, Arabic, French and Brazilian Portuguese. SUBSCRIPTION Listening features require an auto-renewable Weekly or Annual subscription. Payment is charged to your Apple Account when you confirm the purchase. The subscription renews automatically unless canceled at least 24 hours before the current period ends. Manage or cancel it in your App Store account settings.
