a scrolling tracker
Work has started on DoooM a simple yet hopefully informative android usage tracker that reflects the recent history of scrolling activity.
Having previously made a progressive web app in the form of when-ze-bus, we're now looking at system level programming with Kotlin, a Java compatible language that can receive android's AccessibilityService events, giving it the ability to reflect on scrolling behaviours.
Scroll increments _seem_ to be measured by distance rather than individual actions: a side swish maybe just one or two points, a little vertical swish (such as when reading) will result in the counter going up a handful, but a big infinite-feed type swash can result in tens or even hundreds being added to the daily tally. I'm still getting a feel for how it works, but it does seem to be generally reflective of usage behaviours. A normal day's scrolling through feeds may see thousands, perhaps tens-of-thousands, of points being added up.
The f-doid packaging process awaits, and a couple of features lined up, but in the meantime, it can be evaluated with this package, and checksummed to confirm the file is the one intended:
