Awesome product!<p>10 years ago when I moved to Germany I had a similar learning system. I read books, I highlited the words I wanted to learn and once or twice a week I wrote them up in a small book. After a while a wrote a small VBA flashcard app for tracking my progress and randomizing the words. And that took a hell lot of time. With an app like yours I could have saved 30-60 minutes every week (2-4 hours every month) which is worth of 20-40€ a month (on minimum wage). That´s why a recommend you to spend way much more time marketing your app and finding the right customers, which means:<p>- already learning languages (don´t get fooled by &quot;If I had enough time, I would use it&quot;)<p>- learning languages because they have to (living abroad or working international)<p>- saving 2-4 (or more) hours a month is worth them at least 10€ (no students spending more money on boose than on books)<p>IMHO you can find a lot of young professionals on forums like the &quot;new in wahetever city&quot; groups or expat groups in facebook.<p>Good Luck!
