Questions
I downloaded this app like 2 minutes ago tbh but i have some questions: 1: is there like a premium that you have to pay for? Because I read all the reviews (i like reading reviews for some reason) and some of them complained about premium and I downloaded it expecting to see premium or something but it just said you are already premium so I'm confused on that, 2: the words/lessons, how is words like legend, amend, resign, etc in the last/hardest(????) lesson and words like qualify, abandon, oath, etc in the first/easiest(????) so I'm really confused
English Audio Reading French Words Not Good
I set up the app to ostensibly teach me intermediate-level French vocabulary. The French words appeared in individual cards with French synonyms and example sentences. All fine so far. But when I pressed the audio pronunciation button next to the French vocab words, the built-in text-to-speech reader was an English voice which wrecked the pronunciation of the French words. This made the app essentially useless for my purposes. Unfortunate to say the least.
Make your App much better👍🏻
As an English learner, I love his app as much as their book, but I would like to see some translations in different languages. Because in other languages(Russian, Turkish) sometimes meaning of words are similar, furthermore I hopes if you have some extra information, as phrasal verbs and collocations or idioms. Make you app better and everyone will like it.
doesn't work
I can't open the app. what's the problem?
504 review
It’s the best app that I have used in my entire life, I really appreciate creating such an amazing app
Terrible
Please I’m waiting for new update . This app doesn’t even open properly!
Suggestion
Tnx for you app but i wanna say the reader wasnt good . She reads rapidly n i couldnt realize very well as a amateur person. at least for simple parts should read slowly . Tnx again
Dont update
Don’t update the app if you already installed the old version, because in the updated version you need to pay money if you wand to access to lessons of the second half of the book. It’s kind of cheat and I feel stupid that i updated the app.
My idea 💡
Easy to learn 😉
Data tracking
Sketchy they want to track you across the different apps and websites you use: your user id, device id, usage data, and diagnostics. Instant delete. Edit: don’t believe their response, they would not be required to ask for consent if they didn’t track your data across services owned by other companies. Edit again: the person responding to reviews clearly doesn’t understand data tracking across apps and websites from other companies, sketchy when your app is doing it and it’s literally disclosed on your product page ha
🙃
У меня есть эта книга.Я выучила все слова хотелось бы поиграть ,но всё платно. Мне нравятся флеш-карточки.Отлично для повторения.
Pronunciations do not work in version 4.0.0

Improvement!
Very excellent practice! Im not a english person so this helps me a lot by learning all these words and the sentences that included words that are previous lesson practice.
The worst App I’ve ever seen!
This was the worst app I’ve ever seen! You just can use the flashcards. Nothing else! The pronunciation sounds robot-like. It’s not the original one of the book. And it’s constantly asking you to go on premium. I just uninstalled it after day one.
Is it 504 essential word book??
Is it 504 essential word book??
Don’t have dark mode
😵💫😵💫😵💫😵💫
Lier
You are lier. First give an update as bug fixes. But after update half of book block and i can not see them. Do you know why? Because I am not a premium user!! What a surprise. You are lier
Useful vocabulary exercising on the go
It’s very convenient to use this app instead of the book for learning and reviewing vocabulary any time and in any situation. Yet some other features can be added to make it better, like 1-adding part of speech of each word.2- adding a note box in each word’s place to add notes and personal examples. Thanks for your attention.
Review
this app perfect for who want to learn English
Not free

Schön
Schön
Exhusting app ever seen!
I can assure it is one of the most boring apps I ever seen in AppStore! First use=Uninstall. Certainly there are more interesting and far better 504 apps in the store with wider range of functionalities and far user friendlier design. Advice for app’s developer: It would be a good idea that firstly search the store for similar apps and then release a competitive app!
I am satisfied
It is helpful and also a great application
Zhanteh
Amazing!!!!
There is not any word into the app
There is not any word into the app
Nice app
