Perfect OB Wheel & Tracker
The pregnancy wheel, perfected
Simple, fast, and more thorough than any other pregnancy wheel for iPhone and iPad — better than just a replacement for your trusty paper wheel. Perfect OB Tracker adds your whole patient panel.

Your whole panel, at a glance
Perfect OB Tracker keeps any number of pregnant patients with at-a-glance due date and gestational age. Sort by name or due date, search by name or medical record number, and keep notes and a photo on each patient. Track postpartum too — delivery date, gender, and name. A Quick Calculator handles one-off calculations without entering patient data.
Dating done right
Start from whichever date you have — last menstrual period, conception date, estimated date of confinement, or ultrasound dating ("X weeks as of a date"). Enter it your way: the intelligent numeric keypad knows when you've finished typing the month and advances on its own, or spin the classic date wheel.

Thorough, exact results
Everything a classic wheel gives you, plus more: due date, LMP and conception dates, first- and second-trimester end dates, gestational and conceptional age, and expected fetal length and weight from standard growth curves — for when the question is "how much does my baby weigh, doctor?" Exact dates, with all calendar variance handled, leap years included. Results are as-of today, or any date you choose.

Careful with patient data
Passcode locking protects patient information, and optional iCloud sync keeps your devices in step. The latest update adds a full database backup export and automatic local snapshots for extra data safety.
The classic Wheel
Prefer the single-screen classic? Perfect OB Wheel is the same trusted dating engine in a $1.99 app: pick a date, get every result, done. It remembers the date type you last used, and an in-app upgrade to the full Tracker is available whenever your panel outgrows it.
