I had paid membership for years. In 2022, it seemed something was wrong with the application that caused Ads shown on the application. Then, I canceled and applied again in the year 2023. Yet, Ads were still shown, then I canceled as suggested by staff. He informed me to wait for the refund. And there was no refund or contact from such staff.

Simple and easy to use. No transliteration for Thai words or audio for Thai language is a downside.if developer can add that it's a complete dictionary for 5 stars
