AI code is a programmable calculator for Android.
AI code supports Forth-style definitions, variables, code import and lamda expressions. The latest update adds Vector/Matrix operations and statistics. Along with the color coded editor it is a new concept of using a programmable calculator.

I was in Maui for a few days at the Westin Maui Resort, Ka'anapali. The Garden next to the pools just nicely matched the "wwp921 Set" event of WorldWidePanorama.

AI code is a programmable calculator for Android.
It is also available within the StockRoom App to support financial calculations.

AI code supports Forth-style definitions, variables and lamda expressions. As an engineer, I have been using a HP calculator since University and this is how I imagine a modern programmable calculator. The app comes preloaded with lots of example code to try out.
Use :clearcode to remove all examples, and :defaultcode to restore all examples.

StockRoom is a financial stock tracking app for Android which I have developed with some talented young engineers.

It was a great learning experience using the most recent Android APIs and the Kotlin language to create a native app. The code structure is clean and simple and is using LiveData technology to present the stock data in all the activity screens.
