Kivy

Kivy is a multi-platform GUI framework for Python.

From the docs, "Kivy runs on Linux, Windows, OS X, Android, iOS, and Raspberry Pi. You can run the same code on all supported platforms."

In other words, Kivy holds the promise of facilitating using Python to create mobile apps for iOS and Android.

Be warned, the default tutorials on kivy.org are not at all helpful.

Fortunately, the people at RealPython have written a much better tutorial. Have a go at learning Kivy at realpython.com/mobile-app-kivy-python/.

More updates after I have the opportunity to try it out myself ;-)
