The ASRA COAGS app has been updated with a universal code base and a fresh new look. This subscription-based app is $6.99/annually or free with ASRA Pain Medicine membership. The app transforms the American Society of Regional Anesthesia and Pain Medicine anticoagulation guidelines for Regional Anesthesia and Interventional Pain Procedures into a quick and easy reference for your practice. It provides rapid access to drug-specific summary information. This version combines the most current recommendations from two separate publications: 1.

The app provides direct access to both the regional guidelines and the pain guidelines, also allowing you to choose a default and focus on your specific practice area. Regional Guidelines: 1. Search for drugs by brand name or generic name. 2. Get recommendations based on the block type (e.g. neuraxial, peripheral, obstetric) and the intervention type (e.g. placing a block or removing a catheter). 3. Access more detailed information by using the Information "i" button: a. Mechanism of action for each drug. b. Executive summary for each drug. c.

Verdict
The clearest difference is rating: RezClock at 2.3 against ASRA Coags's 1.3. RezClock also leads on iOS requirement (10.0 vs 13.4). ASRA Coags's advantage is in-app purchases (none vs 1) and update cadence (every 3 months vs every 35 months). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. RezClock sells 1 in-app purchase, starting at $0.99 per month. ASRA Coags asks for nothing beyond the download.
RezClock holds the better App Store score, 2.3 against 1.3. That said, the two scores are not equally well evidenced: ASRA Coags has 407 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 10% of ASRA Coags's written reviews are positive against 0% of RezClock's, so the app with the better star average is not the one people write more warmly about.
ASRA Coags ships an update every 3 months, RezClock every 35 months. The most recent releases landed on October 14, 2026 and October 2, 2026 respectively.
