Due Date & Contraction Counter
Free · Designed for iPad. Not verified for macOS.
Bauchbewohner – your pregnancy calculator for parents-to-be, midwives and doctors. Due date, fertile days and contractions: calculated simply, with the formula and source for every calculation.
DUE DATE CALCULATOR
• Due date by six methods: Naegele's rule, 280-day rule, day of conception, IVF embryo transfer on day 3 or day 5, known due date
• Current week of pregnancy (e.g. 20+3), day of pregnancy and trimester
• Week-by-week overview of the whole pregnancy, also for a future date when planning
OVULATION CALCULATOR
• Ovulation, fertile days and next period from the first day of your last period and your cycle length
• Possible implantation
• Calendar with all dates at a glance
CONTRACTION TIMER
• Time contractions at the tap of a button: duration and interval
• Statistics for the last 60 minutes
• A note as soon as your contractions have been regular for an hour (guidance from the Austrian midwives' association and the Austrian health portal gesundheit.gv.at)
• The log stays on your device and is deleted 24 hours after the last contraction
SOURCES AND PDF
• Every calculation shows its formula and tappable sources, including gesundheit.gv.at, DocCheck Flexikon, ACOG and Wilcox et al.; many of them are in German
• Export as PDF, e.g. for your next appointment with your doctor or midwife
PRIVACY
• No account, no cloud: all inputs stay on your device
• Delete your inputs in the settings at any time
• The app is free; it shows ads (Google AdMob, with a consent prompt) and contains labelled Amazon affiliate links (amazon.de)
PLEASE NOTE
