Would be helpful if antenatal and postnatal could be in seperate tabs or at least have the antenates first to prevent me from scrolling so far down to the antenatal section. I like to keep my postnatal women on there to refer back to when they are repeat clients. ### 5/5 — Probably the best obs calculator so far *2024-10-24, version 2.5* Easy to use, fast and accurate, simple interface ### 1/5 — Poco versatil *2023-10-02, version 2.5* Guarda a las pacientes que terminaron su embarazo en primer plano y sigue calculando las semanas sin razón. Por tanto, quedan relegadas las pacientes actuales a un segundo plano, siendo difícil su acceso. La información que se puede incluir en cada caso es muy limitada. En general Ku experiencia NO ha sido satisfactoria y muy por debajo de lo esperado para una aplicación con costo ### 5/5 — Needs cloud feature *2023-05-25* I love how practical the app is! Very simple and easy to use, however is frustrating that whatever I have on my phone, is not transferred to my iPad! It’s was an expensive app for such little functionality! I will be extremely satisfied if an update is made to the app to have cloud function!! Please I beg, make that possible!!!!!!! ### 5/5 — Best pregnancy calculator *2023-03-06* I’ve used and tried so many different pregnancy calculators. This is the best one out there!! ### 3/5 — Text on screen doesn’t appear properly *2022-07-26* This overall seems like a useful app which is helping in my obstetrical practice. I was disappointed in that it was not possible to share the data with other team members such as my nurse when she downloaded the app. Also the various menu options on the screen and out all readable attend to squish two small a space. It can still be used but with difficulty. This may be specific to my device which is an iPhone 12 mini. **Developer response:** Thanks for your review and for mentioning the readability issues on the iPhone 12 mini. It's much appreciated! In fact, we just released an update to improve this situation! OB Wheel will now maintain readability regardless of which device you have or what text-size you select in the iOS Settings app. Please update to the latest version (2.4.1) and let us know what you think. Thanks again and take care for now! - Jeffrey ### 5/5 — ดีมาก ครับ *2022-05-01, version 2.3* ใช้งานได้จริง เหมาะกับหมอรับฝากครรภ์มากๆ note ปัญหาต่างๆ ได้ด้วย ### 5/5 — Muy buena *2022-01-10, version 2.3* Muy buena aplicación, me permite tener a la mano la información de mis pacientes embarazadas y con esto identificar las pacientes próximas a parto, ademas de que es posible agregar datos en las nota como si es diabética, hipertensa, etc y los manejos, con lo cual se tiene una idea rápida de l información de las pacientes. La recomiendo ampliamente ### 5/5 — Ob wheel *2021-11-01, version 2.3* หมุนง่าย ใช้งานได้จริง ## Frequently asked questions about Prego OB Wheel ### What does the Prego OB Wheel app do?
