WordHippo

Now you can randomly learn words.It has got a random button and pinch to zoom feature.Gives the word, its meaning and an example explaining the usage of the word.Can be used for Vocabulary building/GRE/GMAT*. Basically I created this app for myself (very elementary app).But some of my friends suggested me to shareit.Since I didn't want to pay $25 for Android Marketplace Developer, I chose GetJar.Screenshot taken using a camera as phone not rooted.Hope it's helpful.Oh as I said there are no ads (ad-free) as this app isn't commercial.Do let me know if someone tries to sell you.Comments ? *I do not take responsibility of accuracy as it is a GRE based wordlist.
