Apps
The apps I ship, and the writing about them
This page leads with the writing about these apps — what each one is for, what it cost to build, and what I got wrong on the way.
Below that are the apps themselves: App Store entry, support page, and privacy policy for each. Those three pages exist because App Review requires a public URL for every app; inside the apps they are reached from the About screen, so you rarely need to come through here.
The products fall into two lines: offline growth (language learning and self-reflection) and digital citizenship (authenticity, memory, and digital selfhood, currently centred on democracy EDC).
