This app has negatively impacted my phone's battery life. I use Echo Frames which does require a constant connection, so I understand it will drain some. Prior to the most recent update, I could expect ~15%-20% loss throughout the day. After the update, I lost 41% in less than a day to this app alone. That aside, the app does that it claims. It's a functional tool and I use it frequently. (Update March, 2022) Still draining. Functionality is even better, but still kills the phone quickly.
