It sucks. Vocab.com only counts the time you are tapping the screen. Example I was working on it trying to get the 45 minutes that we have due done for 17 minutes and when I checked it had only counted 2! As well the definitions are IMPOSSIBLE TO GET,

How I Use It

ITS HORRIBLE. It doesn’t count the time you are reading the question, and it’s definitions are for those in college! I was. Working on it for 3 hours to get 1 hour! I hate this! BOO VOCABULARY.COM IT DOESNT TEACH YOU SH*T!
