CredibleMeds Mobile is a medical app developed by Azcert Inc for patients, healthcare professionals, and research scientists. The app supports the CredibleMeds.org website, which provides lists of drugs in categories that reflect their ability to prolong the QT interval on the electrocardiogram and/or cause the life-threatening heart arrhythmia, torsades de pointes (TdP).

The app offers the most up-to-date version of the CredibleMeds lists of drugs, which can be used by healthcare professionals and research scientists to identify which drugs can cause QT prolongation or TdP. Additionally, the app provides background information on the categories of drug risk and explains the relationship between QT prolongation and TdP. For patients with Congenital Long QT Syndrome (cLQTS), the app provides a separate list of Drugs to Avoid in cLQTS, with the drugs and risk categories described and designated separately.
