Program for memorizing English words for android?

Question

Android

Recommend an application (free) for android with the following functionality:
1. Sets of ready-made word cards.
2. Create your own word cards.
3. No word limit per day.
4. To be able to sort through these sets as much as you like, and to optionally be a random for a set of cards in order to change the arrangement of cards in the set.
In fact, nothing more is needed. Just tired of cutting out these cards from paper. Yes, and it is not convenient to carry them with you, and the phone is always on hand.
Advise something convenient to learn words.

Answer 1

am learning fame through this program. There are word sets and you can also create your own word sets. Difficult words are remembered very well through the "difficult words" function. Trained through Leo and Duo, too stressful. But to teach from fishing with the help of Vemrise, no discomfort.
My nickname is "From_in_From"

Answer 2

Anki

Answer 3

Application for lingualeo, only need to buy gold status

Answer 4

DuoLingo - https://play.google.com/store/apps/details?id=com....
If I understood you correctly, then it fits.

Answer 5

I used LinguaLeo, but without gold it makes no sense. DuoLingo is the same.
Yes, and other applications, I'm sure, bring a small exhaust. The best way is practice. Watch movies with subtitles, read children's fairy tales. The first month is guaranteed to spend more time in the translator than in the book. But then, wow! Not only words are remembered, but also links with grammar. And this is often even more important.
