CredibleMeds Mobile is an iPhone app developed by Azcert, designed to support the CredibleMeds.org website. The app provides access to lists of drugs categorized based on their ability to prolong the QT interval on the electrocardiogram and potentially cause the life-threatening heart arrhythmia, torsades de pointes (TdP).

This app is a valuable resource for patients with Congenital Long QT Syndrome, healthcare professionals, and research scientists. It ensures easy access to the most up-to-date version of the CredibleMeds drug lists, allowing users to stay informed about potential risks associated with specific medications.

CredibleMeds Mobile also offers background information on drug risk categories and explains the relationship between QT prolongation and TdP. This knowledge is particularly useful for healthcare professionals and research scientists who can utilize the app to identify drugs that may cause QT prolongation or TdP.

For patients with Congenital Long QT Syndrome, the app provides a separate section called "Drugs to Avoid in cLQTS," which describes and presents the drugs and their associated risk categories in a clear and accessible manner.
