I’ve killed my previous attempt at a conjugation testing app (WaniKanjigation).
Now I present, Jigen’s Japanese Fun Time (for lack of a better name)
It’s very early, pretty rough, and lacking pretty much any styling, but its there.
Currently has very basic dictionary functionality, which i hopped off part way through to work on the bigger focus, conjugation testing. Randomly selects verb/adjective from the entire JMDict, or filter by JLPT levels. I have plans to add WaniKani levels, and letting you build your own list. No SRS or anything, keeping it simple. Maybe someday at least add ability to keep a record of test results.
Other ideas rolling around in my head too, but time…
