Any tool to learn to write the kanjis using a drawing tablet or mouse?

I’ve been using an Anki deck called WaniKani Kanji Writing Practice. It is best used on a tablet or phone where you can use the whiteboard feature to draw the kanji and match it up with an outline. So far it is working out well. Just read the directions on the download page to see how to use the deck best.

PS: This is not my deck so kudos to the person who made it.

Here is a link to the thread where I found the deck.
