Description

From the listing uploaded by “taeme”.

SmartHertz allows users to change the refresh rate based on the running application. * If your device is not rooted you will have to follow a guide to enable the application * The application uses an Accessibility Service to detect the foreground application and change the refresh rate accordingly. Features: - The application automatically detect the type of application that is running, and set the user preference for similar applications! - Set the refresh rate you want for any application - Lower the refresh rate on low battery - Low refresh rate on ambient display (great for always on ambient display) Although the application works on most devices, we can not guarantee it works for every device. In case it is not working on your device, please send us an email and we will work on it. Note: SmartHertz is only responsible for changing the screen refresh rate, but some applications might be locked to run at a certain number of FPS.
