Limited language support but still effective

App is great but there are areas that need improvement. I am a native Sinhalese speaker ( Sri Lankan ) and the app does not support that language. I don’t have a way around to use the app without selecting an other language as my mother tongue. I believe option for choosing English as the native language should be there. This would be a workaround for people like us. I don’t mind seeing explanation in English for all these sections. Also, app can consider to include Sinhalese as an option as there are 15-18 million Sinhalese speakers and language is already supported in many other places ( windows , google , etc..). Also, there is a high demand for Learniñg English in the country.

Not so advanced!

I liked the app learning format and structure. However, advanced words and phrases are very limited. I purchased this app thinking that I will get new words and phrases on a regular basis. However, it doesn’t seem like it. I completed my whole advanced lessons and now I am left with no advanced words and phrases to learn. Also, although it says advanced, only a few are advanced. What kind of advanced learning is learning living room, bedroom , kitchen ? The app is good but lacks good amount of words and phrases. I can have a better word and phrases database for you to use into your app. I don’t understand how difficult it is to just update the database content. I am seeing this app already got similar reviews in the past.

I want to request for a refund of my purchase. I don’t want to waste $20 on something that’s not useful to me.

Everything is great except the translation

I really like the app overall, except the translations. The translations from one to another language are not consistent with the drawings and long explanations in the same language (since one word can have many meanings). It’s so annoying and confusing that it distracts everything else. It would be even better to have the options to exclude all the parts with translation in it.
Thanks for the great app still!

Developer Response ,

Dear Customer,

Thank you for taking the time to leave such a detailed feedback about our app.
We are sorry that the quality of translations was dissatisfactory for you. We would really appreciate it if you could specify the language pairs that you tried out, so that we would proofread the translations there.

Best regards,
