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 this app 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!

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

There are numerous bugs in the latest version! Dose not support 4 inch display nicely, lags on scrolling, choosing lessons for games dose not make any sense, ...

Please update it as soon as possible,
With Love!

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

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.

Don’t update 504 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 504 .

I can't open 504 . what's the problem?

this is very useful app!!
that the only thing that it doesn’t have is dark
mode!!!

Thanks for the great app but it’s voice doesn’t work for me

It is helpful and also a great application

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

Unfortunately in this update we can’t listen to meaning of the words and examples ,and pdf of book has removed.

Very nice and helps me anywhere
Into the point
Thank you dear programmers 🙏🤩

It’s the best app that I have used in my entire life, I really appreciate creating such an amazing app

Thank you, the problem which I’ve reported has been solved. It’s the most helpful this app application of all.

After i update my app recently
A big problem happen
My app dont play pronounsiation of the words and sentences

Hello, thank you for your app. But it has some problem like i can't use the pronunciation voice

504 perfect for who want to learn English

It been better if it has a litner

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.
