Hey guys! This is my first time posting here (I’m very new to WaniKani as a whole, only just passed level 3!!), but I made a small website for myself yesterday and thought it would be nice to share it with the community.
The website is very, very simple. It simply tracks your progress as you use WaniKani and uses 4 progress meters to tell you how close you are to having completed all of the content on the entire site. It’s really motivating to check in every now and then and watch all the meters fill up! The site will also tell you how many lessons you’re averaging each day as well as how many lessons you’ve done on the current day (resetting at 6:00 AM each morning - I set it up this way because I’m always up past midnight! haha). If the number of lessons you have done in a day exceeds your average then you get a little confetti celebration just for fun. 
The website is totally free (of course), no ads, no download required, no registration, nothing like that. You just click the link, paste in your API key, and that’s it. Your progress will appear on-screen in about a second, and the site will remember your API key for the future so you can keep checking in without having to re-input it each time.
Here is a link to the site for those who want to check it out!
And here is a screenshot showing what the site looks like:
You’ll also notice that the site shows three options at the top: “Learned”, “Burned”, and “Burned %”
The terms I picked for that are dumb and confusing so I’ll explain what they each mean here, haha.
When “Learned” is selected, the 4 progress bars will show the percentage of items whose lessons you’ve completed as compared to total number of items on the site. This setting doesn’t take into consideration the item’s SRS stage - as long as the item has been learned, regardless of how far along it is in the SRS, it will show up as a single point here, divided by the total number of items on WaniKani. This will show 100% progress once you’ve completed all the lessons on WaniKani, even if you haven’t burned everything.
When “Burned” is selected, the progress bars will show the percentage of items that have been burned. For me, this currently just shows 0% on everything because I have not burned anything yet! haha These bars fill to 100% when you have burned every single item the site has to offer (in which case, massive congrats!)
And finally, when “Burned %” is selected, the progress bars show what percentage of the site you have pushed towards Burned status. It’s a little bit complex and confusing to explain, but hopefully that makes sense. Basically, Burned status is when an item reaches SRS stage 9. So if you have pushed an item to SRS stage 5 (Guru) then that item will count for 5/9 of a single point. Then those values are divided by the total number of items on WaniKani. So even for me, while I don’t have any items burned yet, I still have progress in these meters because I’ve gotten all of my items somewhat close to being burned, and it counts that as partial progress! I hope I explained that well. The bars here will also show 100% completion if you’ve burned every item on the site!
Alright, that’s all I have for today. I hope you enjoy my tiny little program and I hope it’s helpful, motivating, and encouraging for you! Please let me know if you have any questions or suggestions and please tell me if you find any bugs or issues so I can make it better!
Update on August 31st, 2023: Added small numbers to the upper left of each progress bar indicating the exact values as numbers in addition to the percentages. For example, “563/6612” vocabulary words learned.
Update on February 2nd, 2024: Added a graph that shows how many lessons you’ve completed on each of the last 7 days. (The graph counts each day starting at 6:00 AM like the other widgets.)
Yeah, I decided to go at full speed, and you might already know this, but 25 lessons is the “magic number” for this
