I can't think of any other application I am so happy to pay for as skritter. Well worth every dime and it only gets better every day. The reason for my so cheerful subject is simply the Alfa function with sentences. Especially the function to get words in the sentences and easily add them to your study. I have added tons of words that way. Usually i take individual characters and look at the sentences for word combinations with this character. I get the new word and example sentence. Amazing! This cross referencing works very great for me. Add some mnemonics here and there and i have doubled the effect of my study. You are an amazing team and your contributions for us students can't be mentioned often enough. The only request i can think of now is the possibility to sign up for a life time membership:-)
