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.

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

to remind user to do reviews

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).

Sometimes, I get a kanji wrong because i accidentally tap the screen somewhere before i even start drawing, etc. In cases like that, it would be good if I could:

 - mark as a flubbed input

 - retry without recording a success or failure, and without revealing the kanji (as this would tell me the answer)

Currently, the only option when this happens is to mark the answer as incorrect, as the fact that i can see the kanji and didn’t draw it means i can’t just assume i’d have gotten it right.

Hello,

I'm wondering if sync support (icloud or any other way) is a planned feature.

I'm considering buying an iPad with an Apple Pencil for more precise drawing, but I would still want to sync the progress with my iPhone since I take it with me much more often.

I tried an Adonit Dash 4 active pencil on my iPhone but up to 5% of the strokes aren't accurately detected which is pretty annoying for the Ringotan usecase.

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?"

Currently it's only possible to review ahead if there's at least one review due.  The user does that review, and is then asked if they'd like to continue with reviews that aren't due.

They should have this ability even if there are no reviews overdue.

ugh.

Eg. should be able to select a bunch at once and marked them as "known" or "unknown"

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!)
