The new app offers quick and easy access to streamlined STI prevention, diagnosis, and treatment recommendations. The user-friendly interface includes more clinical care guidance, sexual history resources, patient materials, and other features to assist with patient management. The STI Treatment (Tx) Guidelines mobile app serves as a quick reference guide for doctors and related parties on the identification of and treatment for sexually transmitted diseases (STDs). The full STI Treatment Guidelines (cdc.gov) can be accessed at https://www.cdc.gov/std/treatment-guidelines/default.htm. The guidelines provide current evidence-based prevention, diagnostic and treatment recommendations that replace the 2015 guidance. The recommendations are intended to be a source for clinical guidance. Healthcare providers should always assess patients based on their clinical circumstances and local burden.

This clinical decision-support app is intended for use by healthcare professionals and unifies two cardiovascular prevention tools: the 2013 ACC/AHA Pooled Cohort Equations (previously known as the ASCVD Risk Estimator) and the American Heart Association’s PREVENT™ Calculator. Combining traditional ASCVD risk modeling with modern cardiovascular-kidney-metabolic (CKM)-inclusive risk equations, CVD Risk Estimator Plus supports comprehensive, personalized cardiovascular disease (CVD) risk assessment and clinician-guided decision-making. The results and recommendations provided by this application are intended to inform but do not replace clinical judgment. Therapeutic options should be individualized and determined after discussion between the patient and their care provider. CVD Risk Estimator Plus computes risk estimates using: • 2013 ASCVD Pooled Cohort Equations (PCE), which calculate 10-year and lifetime risk of atherosclerotic cardiovascular disease using age, sex, race, blood pressure, cholesterol profile, diabetes status, and smoking status. • 2023 PREVENT™ Equations, which estimate 10- and 30-year risk for total CVD, ASCVD, and heart failure (HF), incorporating kidney and metabolic health measures such as BMI and estimated glomerular filtration rate (eGFR), and supporting optional predictors including urine albumin creatinine ratio (UACR), hemoglobin A1c (HbA1c), and social deprivation index (SDI). Clinicians can toggle between Pooled Cohort and PREVENT™ risk trajectories to support guideline-aligned prevention discussions. This clinical decision support app provides: • Risk category classification (low, borderline, intermediate, high). • Personalized guidance informed by published guidelines, including statin therapy considerations, lifestyle interventions, and risk-enhancing clinical factors. • Export functionality supporting print and email of results for documentation and patient communication. • Resources page with related tools and informational materials for clinicians and patients, including links to source guidelines and reference documents.

Verdict
The clearest difference is rating: CVD Risk Estimator Plus at 5.0 against STI Tx Guide's 3.5. CVD Risk Estimator Plus also leads on iOS requirement (13.0 vs 15.0). STI Tx Guide's advantage is ratings volume (36 vs 1). On price, review sentiment, update cadence and ads 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.
CVD Risk Estimator Plus holds the better App Store score, 5.0 against 3.5. That said, the two scores are not equally well evidenced: STI Tx Guide has 36 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 36% of STI Tx Guide's written reviews are positive against 32% of CVD Risk Estimator Plus's, so the app with the better star average is not the one people write more warmly about.
STI Tx Guide ships an update every 2 months, CVD Risk Estimator Plus every 4 months. Both last shipped on October 17, 2026.
