Good service for free

I started to learn vietnamese with another app from the app-store which i had to pay for.
This app uses many words not explained in the lesson. Vietnames dictionary helps me a lot to understand these lessons. Also in daily conversation i use it often.
As a beginner i sometimes would like to find the right vietnamese words without showing the correct accents.
