Recently I rated an app 3stars (★★★) in the Play Store. Basically, they offered a course by hyping the content, but when I enrolled, I discovered that it had very basic videos for the money they charged. They asked me to rate it higher and support their effort, but I reduced it to ★★. It may seem rude, but I felt my review would help others to understand their marketing tricks.
Truth and lies both hurt, but in the long run it is best to be truthful.
