A dev tool with a monthly subscription? That's enough to stop me right there.
An alternative is B4J, a free (as in beer) BASIC that compiles to Java, so should run just about anywhere. It also has
* B4A - a free version for Android * B4R - a free version for Arduino and ESP8266 * B4I - a paid version for iOS
The main (sole?) developer is ridiculously responsive and helpful.
