Put your phone face down and press start. Caught Scrolling counts every time you pick up your phone during a study or work session. At the end, you get your phone-free time: your session time minus the time the phone was in your hand. Free, no app to install and no sign-up. Pick a 25, 50 or 90-minute block or a custom one, and run as many rounds as you want. Studying on a computer? Scan the QR code to run the timer on your phone.
