The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
Yesterday I installed Doofinder, and today I received a message from the developer "Your trial period expired. Your account is now limited to 1000 requests/month." The 30-day trial period expired in less than a day. Interesting! Honestly, I didn’t have time to figure out if this app was what I was looking for or not.
