Where to learn the words of any language, ordered by frequency?

Question

IT education

You need such a web service or IOS app:
You are sequentially shown flashcards of words, starting with the most common (frequent) in this language. When I have learned a word, I mark it as learned, and I don’t see it anymore.

Answer 1

Hello. I can’t suggest a web service, but for starters, you can look at the Squadesh lists. It includes 200 words as the most used in the base vocabulary.
Example

Answer 2

There is something similar for iOS . There are different regions.
Pros:
1. Pronunciation
2. Modes (EN->RU,RU->EN, dictation (the word is read in a foreign language, you need to write it correctly), ...)
3. Pleasant design and various tips
Disadvantages:
1. Words grouped in a strange way.
2. You cannot select a field of study (for example, food, it, economics, numbers, etc.)

Answer 3

knowledge of words in itself is not knowledge of a foreign language
