Developer Narek Maloyan publishes the app on her behalf. Every formula comes from its primary source: Hadlock, Robinson, Bishop, Apgar, Gail, Grobman, ROMA, and the ACOG, NICE and Russian Ministry of Health guidelines. Each calculator lists its references, and Settings has the full methodology. YOUR DATA • Everything stays on your iPhone. There is no server • No account, no analytics, no ads • Apple Health data never leaves the device • Lock the cycle tracker with Face ID Languages: English and Russian. Important. The app is a reference tool for clinicians and expectant mothers. It does not diagnose and does not replace your doctor. If your baby moves less than usual, contact your doctor or maternity unit right away. Do not wait. Website: https://arutunyan.doctor/
