About

LastScroll Screen Time Control

Read full description

Last Scroll is for the moment a quick check turns into scroll debt. It does not try to judge all screen time. It focuses on the part you regret: the minutes after you cross your own line. Pick the apps that pull you in. Create Scroll Traps for the moments where you usually lose control — bed rot, lunch holes, work escapes, morning checks, or any custom window. Set your line. Last Scroll tracks what happens after it. If warnings are too easy to ignore, Hard Mode can hold the boundary by restricting selected traps after you cross the line. WHY LAST SCROLL EXISTS A quick check is not the problem. The problem is when five minutes becomes forty. The problem is when “just Reddit” becomes the hour you wanted back. The problem is the part after your line. Last Scroll gives that part a name: Scroll Debt. WHAT YOU CAN DO • Choose apps and categories with Apple’s Screen Time picker • Create Scroll Traps for different danger windows • Set your personal line, such as 10, 15, or 20 minutes • Get warned when selected usage crosses your line • See today’s Scroll Debt • Review your 30-day pattern in Report • Use Hard Mode to restrict selected traps after crossing your line • Create multiple traps with Last Scroll Pro SCROLL TRAPS Bed Rot For late-night scrolling before sleep. Lunch Hole For the quick break that becomes the afternoon tax. Morning Trap For the first scroll after waking up, while the day is still yours. Work Escape For the focus escape hatch during work time. Custom Trap Draw your own line. LAST SCROLL PRO Upgrade to Last Scroll Pro to unlock: • Hard Mode • Multiple Scroll Traps • Longer Scroll Debt history • More ways to hold your line when warnings are too easy to ignore PRIVATE BY DESIGN Last Scroll uses Apple’s Screen Time APIs so you can choose apps and categories through the system picker. Last Scroll does not require an account. Your selected app names are not sent to analytics. IMPORTANT Last Scroll is a digital wellbeing tool. It does not provide medical advice, diagnose addiction, or measure sleep. Scroll Debt values are based on your selected apps, trap windows, thresholds, and recorded activity.
