## Description

Perfect OB Tracker is a fast, thorough obstetrics wheel and patient-tracking tool designed for iPhone. Manage multiple pregnant patients at a glance with due dates and gestational ages, with optional iCloud sync across devices. Sort by name or due date, search by patient name or medical record number, keep notes, and even track postpartum details such as delivery date, gender, and newborn name. A Quick Calculator lets you perform one-off calculations without entering patient data.

It supports multiple date inputs (LMP, conception date, EDC, ultrasound dating) and includes an intelligent keypad that moves automatically between fields. Get calendar-aware results — Estimated Due Date, LMP Date, Conception Date, 1st/2nd Trimester End Dates, Gestational Age, Conceptional Age, and estimated fetal length and weight from standard growth curves. Results default to today but can be shifted to any date, and a HIPAA-compliant passcode lock keeps patient data secure.

## Review summary

Users find Perfect OB Tracker easy to use and good for keeping a client list, especially for midwives and doulas. Its strengths include tracking due dates, baby age, sex, name, and a built-in calculator. However, repeated issues center on syncing across devices (iCloud) being unreliable, a lack of analytics or reporting (no monthly counts, totals, or parity stats), missing postpartum/trimesters data, and no straightforward way to share data with assistants. Some users also report stability issues after updates. Overall, it’s solid for basic OB tracking but needs data sharing, analytics, and reliability improvements.

### Pros

- Easy to use / intuitive interface.
- Keeps a clear, organized list of clients and due dates, making it easy to stay organized.
- Tracks EDD and age of baby post-birth, and has fields to record sex and baby name; includes a handy calculator.
- Helpful for obstetric professionals (midwives, doulas, residents) to quickly see dates and delivery ranges.
- Useful for on-the-go access to patient information.

### Cons

- iCloud syncing across devices is unreliable or broken.
- Lacks analytics: no monthly counts, totals, gravida/parity, or delivery statistics.
- Missing postpartum tracking and broader obstetric data (trimester, delivery outcomes).
- No easy way to share data with assistants or enable multi-user access.
- Stability issues after updates or general reliability problems.
