The whole point of supermemo is that you do it every day. The various "phrasebook" courses offered look terrific, but the pricing scheme is really terrible. It's a subscription service, and the cost is $5 per month, if I remember correctly.

I'm 38. If I live to be 80, that's 42 more years, or 504 months.

That means that to subscribe to a single phrasebook, it would cost me $2520 US. And that's for only a single phrasebook.

If you're 20 years old, you'll probably live to be 90, and it will cost you $4200 US.

This is why I don't pay for the phrasebooks. Sure, there's a free version, if you're interested in being able to ask "Is your watch accurate?" in twelve different languages.

The pricing should be a purchase, not a subscription. This encourages people to keep doing it the rest of their lives, which is the whole point.

ps: These numbers are without interest. Calculating compound interest (at 5%) the cost would actually be $8,519.60 for one phrasebook, for me. If your investments earn 14%, like mine do, the price is $119,442.53...See the compound interest calculator at http://www.moneychimp.com/calculator/compound_interest_calculator.htm

That means they're basically asking my 80 year old self to pay over 100 grand for a phrasebook. I recommend that nobody pay for the language subscriptions until they change their pricing.
