The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
I wanted to try 5 trial day period, but app wanted "approve charge" for after 5 days. May be I dont like it. Why do yo want Approval before the trial days ?
I can not try it, because of this reason i gave 1 star.
If i can not try any app, that app deserve 1 star.
