Flex Scroll is a free Android app developed by Phone Phreak that helps you scroll through social media feeds, web pages, e-books, and blogs without using your thumb. The app adds a floating widget to your screen with buttons for continuous scrolling down/up, page down/up, and page right/left. It also includes a slider to adjust the auto-scroll speed while scrolling.

Flex Scroll offers two speeds for continuous scrolling down/up: normal and slow. You can switch between these speeds using dedicated buttons for faster browsing or slower reading. Additionally, you can set a timer for full-page scrolling and adjust the timer interval using an on-screen slider. The timer can reset each time you scroll a page yourself, making it convenient to use.

Other features include the ability to jump to the top of the page, adjust page size for each app separately, and select the apps where you want the auto-scroll widget to appear. The widget can be hidden in the margin of an app and brought back via a swipe from the edge of the screen. Flex Scroll contains no ads and uses accessibility services to perform gestures for automatic screen scrolling.
