It's a website + AIR app for people who want to learn, but lack motivation. I built it because I wanted to learn Spanish but I'm too lazy to study.
The desktop app shows you a flash card every few minutes (you decide how often) through an unobtrusive Growl-like notification window. If you aren't busy, click the notification to answer the question on the flash card. If you are busy, ignore it and it goes away. It works especially well for getting started with a new language.
Help me make this thing better!
That looks like a 2% conversion to user rate, with a 66% falloff rate between signing up and using the service.
Dismal!
To fix this, I'm thinking I'll try to simplify so the user only has to download the app. The app will ask for user/pass, or will generate a unique APP id from the server, which the user can use to subscribe to flash card sets.
This is the path of least resistance for the user, but I'm worried about problems with this approach. Anyone?
