How to work with software for spaced repetitions of learned words?

Question

English learning tools

Reviewed many applications, both on the web and on the phone. Quizlet and Tinycards turned out to be more or less pleasing to the eye and more or less convenient. Both applications are convenient enough for simple repetition of words without any system. With paper cards, it is possible to make a repetition calendar and you can group the cards as you like, depending on whether the word is remembered or not, you can easily transfer it from deck to deck. ( Leitner system ). We need the same functionality and preferably in a mobile application, in extreme cases on a PC.
In the mentioned applications, it is possible to create decks of cards and there is a function to enumerate these decks. But ... they do not have the ability to transfer words to another deck, which must be repeated, for example, once a week.
I don’t understand how to work with applications in which you can simply sort through the cards.
Inconvenience arises when every day you need to add, for example, 30 new words and also repeat them at intervals along with those already added. As a result, it turns out that in 30 days there will already be 900 words in stock and it’s not clear how to repeat them ... some words need to be repeated after 2-3 days, some after a week, some after 2, etc. Not sure how to track it. And repeating 900 words each time is neither smart nor efficient, not to mention the large amount of time spent on repetition. And every day there will be more and more cards. And with interval repetition according to the system, a large number of cards will need to be repeated roughly once a month.
offline, you can safely shift cards from one pile to another.

In general, tell me from your experience how to learn words with interval repetitions using applications on the mob. or PC. I know there is also a powerful Anki application, everything seems to be more thought out there, and there is a kind of interval repetitions, at least with each repetition not all words are shown, but those that were poorly memorized ... But Anki is a wildly old program, terribly inconvenient and besides, there is no adequate mobile application (especially on IOS ... it costs $ 20)

Answer 1

You are pulling a cart. There is also Anki, in the same place the intervals are automatically put down. Slightly outdated interface, but does the job. There seems to be a mobile version as well.
