Ultimate QTc/QTp calculator
EP QTc is an iOS and macOS app that simultaneously calculates QTc (corrected QT) and QTp (predicted QT) intervals using many different published formulas. Detailed information on each formula is given and the results can be graphed and imported into text editors or spreadsheets. The app uses the QTc framework. For more background see Hacking the QTc.

Thanks to Marian Stiehler for help in acquiring the original literature that forms the basis of these QTc and QTp formulas.
Thanks to Dr. Simon Rabkin at the University of British Columbia for corresponding with me regarding the QT interval, and for his and his team's fine work on the nomenclature and categorization of the numerous QT formulas which formed a basis and inspiration for this app. I also thank the multitude of investigators who over the years have attacked the problematic QT interval, using math in an attempt to flatten nature's heart rate versus repolarization curve.
