Preop Eval organizes and presents much of the guidance that one needs in order to evaluate and prepare adult patients for non-cardiac surgery. It is based upon the guidelines on this topic from the American College of Cardiology, the European Society of Anaesthesiology, the American Society of Anesthesiologists, the Institute for Clinical Systems Improvement, the American College of Chest Physicians, and more (full references in the app). The app contains 1 algorithm and 3 resources: the cardiac evaluation algorithm, guidance on starting and stopping key medications in the perioperative period, guidance on timing of surgery after cardiac events, and guidance on preoperative testing. It also contains a review of preoperative evaluation mainly for students and residents. The app addresses such common questions as: - who needs bloodwork before surgery? - who needs an EKG or a CXR? - how do I handle patients on warfarin, clopidogrel, and DOAC's? - which patients need adjustment of perioperative insulin and diabetic meds, and how? - which active cardiac conditions preclude surgery? - how long after MI or stent should a patient wait before surgery? - are there adjustments to make on psych meds, rheumatologic meds, ACE's and ARB's? This app is written and intended for practicing physicians like internists, family physicians, and hospitalists; for resident physician trainees; and for medical students. In addition to being a reference, the algorithm is written to be a teaching tool by not just delivering an answer, but instead walking a physician through the evaluation process so that one learns that process along the way. As an educator and clinician, I am interested in feedback and I would be grateful for guidance on improving the tool.

Verdict
The clearest difference is update cadence: RaceSafe at every 3 weeks against Preop Eval's every 6 months. RaceSafe also leads on review sentiment (86% vs 67%) and ratings volume (12 vs 2). Preop Eval's advantage is rating (5.0 vs 4.6). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Preop Eval holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: RaceSafe has 12 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 67% of Preop Eval's written reviews are positive against 86% of RaceSafe's, so the app with the better star average is not the one people write more warmly about.
Preop Eval ships an update every 6 months, RaceSafe every 3 weeks. The most recent releases landed on September 10, 2026 and September 16, 2026 respectively.
