## What is Perfect OB Tracker?

Simple, fast, yet more thorough than any other pregnancy wheel available for the iPhone, Perfect OB Tracker is better than just a replacement for your trusty paper wheel.

 • Keep track of any number of pregnant patients with at-a-glance due date and gestational age
 • Synchronize to all your iOS devices via iCloud (optional)
 • Sort by name or due date
 • Search by name or medical record number
 • Keep notes on each patient
 • Track postpartum, as well, noting delivery date, gender, and name
 • Quick Calculator lets you use the OB wheel without having to enter patient data for one-off calculations

1) Start with one of: 
• Last menstrual period (LMP) 
• Conception date 
• Estimated date of confinement/delivery (EDC) 
• Ultrasound dating: Number of weeks and days gestation as of a given date ("X Weeks"). 

Enter dates quickly with the intelligent keypad (which knows when you're done typing the month, for example, and automatically moves to the day) or with the spinning date wheel.

2) Get thorough results: All the information you would expect from a classic wheel, plus more: 
• Estimated Due Date 
• LMP Date 
• Conception Date 
• 1st Trimester End Date 
• 2nd Trimester End Date 
• Gestational Age 
• Conceptional Age 
• Expected Fetal Length based on standard fetal growth curves 
• Expected Fetal Weight based on standard fetal growth curves ("How much does my baby weigh, doctor?") 

Results are relative to 'today' by default; this can be quickly changed to reflect any date by tapping the 'today' button and selecting a new date. 

3) Accurate results: Perfect OB Wheel provides exact dates and accounts for all calendar variance, including leap years. 

4) Secure: HIPAA complaint passcode locking keeps your patient information safe

### 5/5 — Ótimo

*2026-06-05*

Atende bem às expectativas. Bom espaço pra anotar. Bom armazenamento; só queria um espaço pra LOGIN que que pudesse resgatar os dados caso eu mude de aparelho.

### 5/5 — I love this app

*2024-09-18, version 3.9*

This app is easy to use and is convenient

### 1/5 — Can’t get the app to work right!

*2024-03-14, version 3.9*

I’ve had this app for years. It just stopped working properly. I thought if I upgraded to the pink from the blue one I’d end up getting out the bug, however many weeks the woman is plus days? It only states weeks. Please help.

### 5/5 — Exelente

*2024-01-04, version 3.9*

Exelente aplicación solo pido que no la quiten como otras que he tenido y se esté actualizando

### 2/5 — App parou

*2023-10-07*

Meu aplicativo parou do nada .. Gostaria de ajuda para voltar a funcionar

### 4/5 — Fine app

*2022-09-23, version 3.9*

This is a good app for keeping track of clients. I’m a midwife and wish it had a few more options for writing notes and to make a r more customizable for our practice. But it does what it does well.

### 5/5 — Midwife

*2022-03-10, version 3.9*

I use every tool in this app. I love that it track not only the EDD but also the age of baby post birth. And the spot to record sex and name of baby is so helpful for tired midwife brains. I frequently use the calculator as well. My only request would be a way to share data with my assistants so that we don’t all have to enter the same clients. 🤞🏼💜

### 4/5 — I use it every day

*2022-02-24, version 3.9*

So happy with the update to add delivery date and postpartum calculations!! Now if I could export a list to Word or Excel that would be really great. (Even just the ability to copy and paste would be great)

### 3/5 — Perdi os registros

*2022-02-18*

Muito bom, mas, ao mudar de aparelho de celular, perdi todos os meus registros.

### 5/5 — Wish list

*2022-01-30, version 3.9*

I would like to see a list of how many pts are due each month through the year Thank you!! OB/Gyn Hook
