BE CAREFUL its a scam!!!!

I paid for a week to try so they don’t charge my account but after the one week subscription finished I saw a charge for a monthly or yearly subscription made to my account. You see a cancellation option but it takes you to endless customer service chats of back and forth messages that try to convince you to stay then at last they offer you cancellation but nothing about a refund!!!!

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.

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.
