Hi! I'm building an open source web/android japanese dictionary and it would be great to be able to use that (instead of jisho).

I recently added the option to open jiten.obfusk.dev links in the app (on master, no release yet), so you should be able to just use an intent to open a https://jiten.obfusk.dev/jmdict?query=単語&exact=yes link to support both the app and the website.
