v4j is a small desktop app that you can use to learn Japanese verbs through example sentences. You start your learning journey from the most used verbs and progress your way to the ones that are rarely used.
v4j comes with over 500 verbs and 10000 sentences.
We currently have Linux, macOS, and Windows versions. When you purchase v4j, you get to download all of them.
v4j tries hard to be clutter-free and simple. It shows only a single verb and a
single sentence at once. You move through verbs and example sentences using
w-a-s-d or h-j-k-l keys. You can toggle English translation of the sentence by
pressing e, toggle verb-highlighting by r, and go through Furigana settings by
pressing f. Here are the keys that you will use:
s (or j): go to next verb w (or k): go to previous verbd (or l): go to next sentencea (or h): go to previous sentencee: toggle on/off English translation of the example sentencer: toggle on/off highlighting of the verb in the sentencef: go through Furigana settings (hide Furigana -> show Furigana on mouseover -> always show Furigana)Software settings (Furigana, English, Highlighting, WindowWidth, WindowHeight) and current verb/sentence pairs are stored in a database (.v4jsettings.db file in your home directory). v4j does not collect or store any other user data.
