1 Edge is a Floating Window Edge Panels application for Android devices that offers a variety of features. It is similar to Samsung Edge, and it provides app shortcuts, countdown days, drinking water reminders, a timer, tools like a compass and ruler, and an RSS feed subscription. The app is free to use and very powerful, allowing users to switch between different panels by simply swiping left or right. The floating window feature enables users to use it anywhere. However, some users may need to grant Accessibility service permissions to use the HOME/BACK/RECENT button click.

The app is a great tool for those who want to have quick access to their favorite apps, count down important days, and keep track of their water intake. The timer and tools like a compass and ruler are also useful for everyday tasks. The RSS feed subscription feature is a nice addition, making it easy to keep up with your favorite websites. Overall, 1 Edge is a useful and powerful tool that can help improve productivity and organization.
