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

Casemate is a voice-first practice tool for medical, PA, and NP students who want real reps at taking a history. You pick a chief complaint, tap Start, and talk to a patient. The patient talks back. When you finish, an OSCE-style rubric — informed by the published consensus frameworks for clinical communication (Kalamazoo, Calgary-Cambridge, Four Habits) — grades you on what you asked, what you missed, and how you communicated, with quotes from your own transcript to back up every point. What's inside v1.0 - 150 cases across 30 chief complaints (chest pain, abdominal pain, headache, shortness of breath, joint pain, dizziness, and more). Each complaint ships five variants spanning beginner, intermediate, and advanced difficulty. - Voice-first encounters. No typing — you talk the way you would in clerkship. - A four-dimension rubric (history, clinical reasoning, communication, patient safety) with every criterion tagged by framework lineage — Kalamazoo, Calgary-Cambridge, Four Habits, or ICE — so you can trace what you're being graded against. Overall score weighs patient safety double. - Cited feedback. Every criterion points at a timestamp and a direct quote from your transcript. - History and trend tracking so you can see your score curve over time. - "Study this" links at the end of every encounter to the primary-source reference you likely need. Built for trainees, not patients. Every patient you meet is AI-generated. Nothing in this app is medical advice, a diagnostic tool, or a substitute for supervised training. We confirm this at onboarding and reinforce it on every report. Age 17 or older; trainees only. Your privacy - Anonymous by default — no login required. - No voice recordings are stored. Audio is transcribed in real time and the audio itself is discarded. - You can request deletion of your server-side transcripts at any time. Pricing Every new account starts with a 7-day free trial with full access — no payment info required. After the trial, Casemate Pro is $9.99/month or $89.99/year (about $7.50/month). Subscriptions renew automatically until cancelled in your App Store account settings. Feedback welcome at alichah414@gmail.com.
