I didn’t hesitate to get Lifetime and I would do it again. I have the flexibility of pausing my SRS and going back to it plus the holiday deal is excellent (and I can use it however I want in the future). I’ll have the grammar glossary for life which I use all the time. BunPro is arguably very underpriced for the value it provides. Plus, I’ve been adding my own custom sentences. Some numbers for perspective:
$120 is ~ 6 italki lessons for six hours assuming $20/hr pro teacher
First google hit for Japanese major was Stanford University so an extreme example. They charge ~$1200 per credit hour (and then consider a 120 hour undergrad schedule). So just pretending, a 4 credit course and 15 weeks…your cost to attend a single day class is higher than your lifetime subscription to BunPro There are other examples like the price for language school both in US and going to Japan which are price heavy, perhaps Europe is better but I wouldn’t know.
To keep BP growing, I think users like to see updates no matter how small even though there are areas of improvement. The site has grown considerably since I started. I know they make fixes and updates and don’t report it; I think users like hearing the site is continually being polished or fixed. The growing community engagement is another, WK has had a lot of success in that regard that developed their fanbase. I was so glad find others around the world studying as I do and an invaluable resource.
