Pascal: 3-in-1 Calculator 9.0.1

Pascal (formerly Calculator³) is a comprehensive 3-in-1 scientific, graphing, and programmer calculator. The app is offered for free and includes a feature-rich scientific calculator, Today widget, and Apple Watch app. Unlocking the graphing calculator and programmer calculator requires in-app purchases, but each comes with three trial periods for users to explore their features. Throughout the trials, all functionalities are accessible. For those interested, a tip is to reinstall the app to renew the trial counts.
