Daily dose of excitement

I love this app and hence the five star rating. It’s been years and it’s quite visible to me how it has brought about a considerable change in how I perceive things around me- from understanding to reading. The right information about a word brings about changes that can only be felt over a consistent use of it, and MW has helped me achieving that greatly.
Concise and appropriate options like- marking your favourite words, origin of the word, word’s pronunciation and most importantly, the thesaurus and the word game part is the most amazing one!!
I owe this app a lot!

Helping hand

It is an amazing app and also can be called as a pocket dictionary. I can also say that it is a helping hand for me to increase and asses my vocabulary. I personally love to use MW. Everyone can use this dictionary easily. It is quite effective because it helps to jot down my favourite words and thats how i can easily remember the words and further i can take a glance through that words and not only this but it is the best offline dictionary.

This is the 2nd best dictionary app. It provides meaning of words in very lucid way and it’s sentence usage. The app is designed in very systematical and user friendly manner and does not take time to open.I have used other dictionary apps and their online websites , but Merriam Webster is best in both categories.I am also fond of its quiz part which enables me to check my progress, lacking in many other online and offline apps.
