A handful of jinmeiyou kanji aren't used in any actual words (making them not currently supported). And a lot of the ones that are are so rare we shouldn't be using them as prompts.  It'd be better to use names for prompts instead, the way they're actually used.

Some examples: 燿藥覽偖凭剌哥嗽嘸嚏囀嫋屹掏捩焜犇皰稍窶綽罅聊臘蜀齎跣踉蹌軈閊靨鞦韆飩饂暝

It would be super helpful if in the Custom Review screen it were possible to sort by the number of strokes in each Kanji.

My usual approach to learning new Kanji is to browse for any Kanji that are made up components I've already learned but currently this involves a lot of scrolling and a lot of missed possibilities. If it were possible to sort by the number of strokes in the Custom Review screen it would pretty much guarantee that any new Kanji I pick is either made of components I already know or something irreducible that I will

This has previously been requested but I think has been misunderstood on what's being asked. While your app does automatically back up it's progress from a database perspective, it does not currently share this database across separate devices. This is something that needs to be explicitly setup.  As an example, I currently have your app running on both an iPhone and an iPad. Any progress made on the iPhone is not actively synchronized to the app instance on the iPad. The cloud sync that you currently have is simply maintaining a backup of the app in the case of needing

When reviewing the items in custom review, the order should be randomized

Hi, I use Nihongo Soumatome as my main textbook for Kanji and others. It would be helpful if you can add lesson plan based on this book. Thank you!

According to this question, the word 朦朧 is fairly common, but neither kanji is included in Ringotan.  It seems neither the word nor kanji are listed as common in our dictionaries, but ロス先生 confirmed that it is.  So, let's find more data sources that include this information.

Apparently JPDB lists it as common. Where do they get their information from?

Currently, no lesson contains every kanji supported by Ringotan.  We should create one that does.

Right now after studying it goes straight back to the review screen.  It would be nice to instead see a new screen showing what you learned during the lesson and how you improved (or not!)

ugh.

It would be great to know how long it takes a kanji to go from Aka-chan to sensei. I found I had a bunch them at Tensai and I was wondering for what felt like a long time, "how long will it be before these show up again?"

I've had multiple comments that users were turned off by how daunting the review can look when lots of start/end points are shown. I should make it more clear that these are only hints that are shown while learning, and are not shown while reviewing (unless you get the answer wrong).

Adding a space for inputting your own mnemonics (or copying and pasting from, for example, wanikani).

Gesture navigation (introduced in Android 10) breaks all drawing apps that use the full width of the screen, as far as I can tell.

We should check if the setting is enabled, and if so, show a warning.
