I’ve gathered all users information and created these graphs showing how many users are at what level. The number of all users was at the time of download around 28,000.
Number of people at each level.
Drawing the data in log scale and ignoring the first 3 levels since they are biased reveals something interesting.
The number of users drops exponentially which might be another case of Zpif’s law
Now for some some graphs how many users have given up meaning they are no longer paying. ![|345x207](upload://5F3dZIGReHDoVrKzWn4f1v34a3K.png) How many of the users are not paying for wanikani. All the people after level 3 gave up. It is interesting to the spikes on multiples of 5 like 45 and 50.
The spike on 51 are probably all the people that completed wanikani when it only had 50 levels.
Number of all users that are paying for wanikani. It is interesting to see that allot of users are paying even when they reached level 60.
Number of users that have that have bought lifetime subscription. The only interesting thing to see here is that it rises much slower than paid subscription.
All the data is available here in csv format: https://pastebin.com/eDRCb3rr
If anyone wants to play with “raw” downloaded json files, PM me and i will send them to you. The file size is around 3MB.
Now i have to do my 200 reviews that stacked up while i was doing this (x_x)
