Your app gets me figuring that it would be nice for a dictionary app to have a feature that, after you look up some word a second time (indicating it's not a rare one), adds it to the "to memorize" list and trigger the notification mechanism you wrote.
Also wondering if support for memorizing equations would be straightforward.
Thanks for your feedback. I would say that for the first use case, unless the "memorizing" feature is built in to the dictionary app, it's hard to do it automatically. You could use the OS's "Share" feature to manually add the word to the memory app.
I'm actually looking into displaying math equations. There are libraries out there so should be pretty straightforward.
Thanks for your opinion on this. I use Mac's built-in dictionary quite often. Guess the system provides some way to catch the look-up event, though then I also need to think about the notification part. Anyways spaced repetition sounds like a simple idea that could do the trick. The point of doing it automatically in the vocab learning (for foreign languages) case is so that you don't need to decide whether you've search a word before.
