Not free on AppAdvice: subscription required to see your data
I was delighted to see this app free for a day on AppAdvice; however, it did not show the whole picture. When I attempted to view the recorded data, only locks appeared. After checking further, I realized that to make use of the data, one must purchase a subscription. Folks, that is not free! I immediately deleted the app and wrote a review to prevent others from making the same mistake.
