Calculation capabilities
Core gestational metrics
Calculate Last Menstrual Period (LMP), Expected Date of Delivery (EDD), and conception date from a standard 280-day cycle, instantly.
Ultrasound dating
Estimate gestational age directly from an ultrasound scan date for closer clinical accuracy.
IVF / ART dating
A dedicated calculator for IVF pregnancies, dating from the embryo transfer date instead of last period.
Redate
Enter a Last Period and an Ultrasound date side by side and get ACOG Committee Opinion 700's recommendation for which one should govern the due date.
Trimester tracking
Automatically surfaces the current trimester for quick context during a consultation or check-in.
Patient records & visit history
Save patients and keep a running, timestamped note for every visit. Revise a due date later and the change is logged with a reason, never silently overwritten. Search patients, filter to overdue ones, and mark deliveries as they happen.
Data & safety, plainly stated
Nothing collected by us
Your dates and records stay on your device. Damurka does not collect or receive your personal health data.
Backup, your way
Local backups use Android's system file picker. Drive backup uses a private, app-only Drive folder only this app can read.
Free with ads, or go Premium
Google AdMob shows ads and may use an advertising ID. A one-time Premium purchase removes ads and unlocks the IVF/ART and Redate calculators — or unlock them for 24 hours by watching a few reward videos instead. Firebase Crashlytics and Analytics help us fix bugs and see feature usage.
Clinical note
Pregnancy Wheel estimates 280 days from the Last Menstrual Period to the expected date of delivery, assuming a regular 28-day cycle. It is a supplementary calculation tool and does not replace professional medical judgment — see our Terms of Service for the full medical disclaimer.
