This app provides a detailed week by week assessment of your target weight and helps log and visualize your progress until your baby arrives. And it provides you important week by week information about being pregnant. Weight gain calculations automatically determine your starting body mass index (BMI) and adjust healthy range for underweight, normal, obese and overweight circumstances. FEATURES: - Supports both metric (kg / m) as well as imperial (lbs / ft) - Important week by week information about being pregnant. - Create and save a customized pregnancy program tracking your suggested weight range from conception to delivery. - Log your weight and track your progress on a visual timeline, overlaying the ideal weight range for immediate feedback on your progress. - See weekly and recommended weight ranges for ideal weight gain. - Charts can be zoomed and panned. And this app is well researched and built 100% based on a research paper of a scientific study that has been published by The National Academy of Medicine in 2009. The National Academy of Medicine serves as adviser to the nation to improve health. Established in 1970 under the charter of the National Academy of Sciences, the National Academy of Medicine provides independent, objective, evidence-based advice to policymakers, health professionals, the private sector, and the public. ## Key features - Calculate ideal pregnancy weight gain - Track weight progress weekly - Visualize progress on a timeline - Customized pregnancy program - Week-by-week pregnancy information - Supports metric and imperial units ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/pregnancy-bmi-weight-tracker/id1207919953/reviews.md ### 1/5 — Really waste of money *2019-02-25, version 1.4.1* The app doesn’t work. It’s a waste of money. The save button doesn’t save your info. **Developer response:** App works as intended. Save button does save your info. Please check our other user reviews. ### 3/5 — Weight entry has been updated! *2017-04-14, version 1.1* UPDATE: The method of entering weight has been updated and is perfectly easy now- thank you! The only other glitch I see is that the app is taking my current whatever my current weight is and using it as my pre-pregnancy weight. I started at 127 and am 129 now at 10 weeks, and it says my pre-pregnancy weight is 129. So it's showing I'm under where I should be because it thinks I haven't gained anything. ORIGINAL: I love the graph and how the app tracks, but you have to use a sliding scale to enter your weight, and it is way too sensitive!! It takes me over 5 min to enter my weight each week because when you lift your finger from the slider it moves it, and changes your weight +/- a pound or two. It also doesn't reach every weight. For example, I'm 129.2lbs right now, and my only options, even when moving the slider very slowly and carefully, are 128.7, 129.4, or 129.8. And if course, I finally get it on 129.4 because that's pretty close, and every time I lift my finger it changes the weight. PLEASE update the app so we can just type in the weight. Your slider does not work. For the price this app is very frustrating. **Developer response:** Once again thank you for your feedback. We will fix issue as well with a new update very soon. Edit: However you should never enter your current weight in the 1st calculation screen. You should only enter pre-pregnancy weight there as mentioned. Furthermore you only need to do the calculation just once. All your weight tracking can be done in other screens. ## Frequently asked questions about Pregnancy BMI ### What is the price of Pregnancy BMI? Pregnancy BMI is a paid app and costs $0.99.
