ANDROID USERS BEWARE - THEY WILL NOT REFUND YOU! This app wasn't flexible enough for my purposes. It didn't take into account that I was already fairly proficient and wouldn't allow my to skip over the basic lessons. I realized it wasn't for me within 30 minutes of downloading it. BUT HERE"S THE KICKER: THEY PROMISED 7 DAYS free but charged me RIGHT AWAY. So I followed the instructions to request a refund for Android. I did this within 30 minutes of my initial download and it indicates that it will honor a refund within 30 days. I have contacted them 8 times now and am disputing the $99!!!! (OMG) charge through PayPal as well. They have not responded ONCE! RESPONSE - Funny you should mention that I should "message" you. I've sent you 8 emails since January. You've only responded to one then I got ghosted.
