Please note, the original BASIC! on Playstore became defunct due to lack of updates and changes in Android storage (scoping). You are encouraged to use one of the forks eg. hBasic which can be found on the forum. hBasic can be found furthur down this page.

Edit programs with the built-in editor ( inside  BASIC! interpreter app)
Any desktop editor and then copy *.bas file/s to the Android phone for the interpreter app.

No waiting for compilation or building process during development.
No need for a slow emulator. What you see is 'really' what you get.

When the program is finished, there is a tool to package as an .APK or .AAB
the program and embedded interpreter as a standalone app.
