The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
The Review Caddy app has been useful for us to collect a lot more product reviews and especially product photos on our website. We did have some bugs at first when installing it on our site, but they were very helpful in correcting those bugs and making everything work properly quickly. We didn't want to spend a lot for reviews, so for the price, it's really a great option for us.
