I highly suggest selling lessons individually (and grouped) to those that want to bypass the time-based paywall…It sounds like people on average take a week to do a lesson so why not seem packs of 4 lessons for $10 and individual lessons for $3 each? Encourage people to retain they subs via lower prices but give options for others…
I work from home and have the luxury to be able to pause what I am doing for 5-10 minutes to do other things and WK would be great…except waiting an hour to review 2 kanji and then waiting another 1-5 hours to do that again is well, silly. I am actually setting an alarm on my phone to remind me when I have to look a kanji or two.
We all have different abilities, experience, levels of free time, etc so it’s in your interest to be more flexible with how you offer your product…take a page form the gaming industry; micro-transactions are a money maker…subscriptions based services are a dying breed.
Like the product, site, community, presentation and tracking…but please give me more options…
Cater to your customers…don’t dictate…don’t be Henry Ford: “You can have (a Model T) in any colour as long as it’s black.”
ps. To be clear…really like WK…this is not a flame.
