Frequently asked questions

But it’s impossible to learn a language in just 5 minutes a day!
Yes, that’s right. Our app won’t replace a textbook or courses — it’ll just help you to remember what you’ve learned. And you still need to spend 1-2 hours a week to make your cards, but to review them 5-15 minutes a day will really be enough.
Why are there just two buttons in a review? What if I know the word but not very good?
You either know it — and can use it in a conversation anytime, — or you do not, because in some circumstances you won’t have all the time in the world to search through your memories for the word you generally know but can’t recall instantly.
Why there’s no separate themes in one subject?
When you think you’ve learned the theme, you move on to the next theme and forget entirely about the previous one. SRS is made for not forgetting anything, so there’s no need in themes.
What if I didn’t have time for review today?
It’s okay, you can review some cards right now or during the day and cards that you didn’t have time to review today will appear in tomorrow’s review along with cards that you should review tomorrow.
What if it won’t work for me or I won’t like it?
We’re sorry. Tell us, which part you didn’t like here. Anyway, you can export your data from the app anytime to use it elsewhere.
