The best app for memorizing words?

Question

English learning tools

Here the question is about the effectiveness and correctness of their memorization. For example, Duolingo gives you a good base, but makes you learn a lot of words you don’t need, which in the end are simply forgotten. Lingualeo - everything is fine, but there are no "words in examples" and spaced repetition. Anki - here the word is up to you, more specifically, I would like to hear about AnkiDroid. Lingvist - interval (or did it seem to me?) learning, but again does not give a choice in learning the right words, since there is no dictionary. Memrise - again the word is yours.
It was my opinion about what I know and what I used. Browser extensions will not be discussed, since all training takes place from the phone. What do I want from the application? A dictionary where I can add words and learn them. Not just like in Lingualeo, go through the words once and that's enough, namely, according to some kind of repetition technique. I also need to be able to quickly transfer words from FBReader to this very application, one click is not enough, I understand, but the less gestures, the better.
Unfortunately, the pen + paper method does not help; for the same spaced repetition, I have to start entire Talmuds and leaf through them, frantically trying to remember this or that word. Therefore, I ask for your help in choosing such an application based on your experience. I tend to AnkiDroid more, but I need your advice.
PS Rosetta stone and Murphy (application) will be attached to this system, I can't get by with just words.

Answer 1

regularity
no magic tricks ,
just regularity
for example, yes, Anki.
why DuoLingo and LinguoLeo did not suit you - it's not clear.
no words will be superfluous.
and those that you already know are soon removed from the repetitions.

Answer 2

There are also BBC courses , both words and grammar on various topics go at the same time.
