@roptat Thank you so much! I am currently using #Takoboto and have been waiting for a free software dictionary on F-Droid.

I would love to see some kind of +1 button or a word list feature. My current routine is to add new vocabulary to my #Anki deck in order of "how many times did I have to lookup this entry".

Also the Takoboto killer feature: Simple regex. Searching "操？" will yield 操作, 操縦, 操業, etc. which is super useful when you can recognize 操 but not 縦 while reading a book.
