Is there a reader for ios with translation?

Question

iOS

Good time community.
I ask for advice on choosing a reader for iOs (if there are examples on Android, I will be glad to remember)
The requirements for the application are simple:
1. The ability to translate both one word and a sentence
2. The ability to take into account the words that I translated
I want to improve technical English in this way, I plan to start with "Complete code" Mcconnell
