There are many calculator emulators in the App Store, some of which have simple programmable features, such as HP and TI financial and scientific calculators. There are some with computer algebra and user function definitions. There are some BASIC interpreters: iBASIC. SmartCalc uses a BASIC interpreter with disabled access to BASIC (BasicMatrix version was turned down). There is a way to package a web app (HTML, CSS, JavaScript) as an App Store app. JavaScript-based programming is allowed. And it is possible to implement any interpreter in JavaScript.
