Conflicting impressions.
On the one hand, this is a very attractive application. But there are too many flaws to be able to call it a full-fledged application for learning Thai. Especially for money. Firstly, there is no explanation of the Thai alphabet. Secondly, there are practically no theoretical lessons, grammar. Thirdly, there are very few training sessions. For a free app, I would put 5 stars. But for a paid subscription, the service should be more thoughtful and filled.
