Folks: there's a built-in technology on your phone that allows you to load and run an app on-demand over the internet without dedicating any internal storage at all! It allows clean integration with many of the "native" features you expect like camera and notification and timers and stuff. And it's based on completely open standards with multiple, competing open source implementations.
No, seriously: uninstall that junk and just run stuff in the browser. It works much better than you think, the biggest annoyance being all the nag screens sites throw at you to get you to install their apps.
