• Users set boundaries, invite trusted friends, and if they want to override a limit, their accountability partner must share a code.
• The app aims to make screen-time management social rather than relying solely on individual willpower.

Evidence strength Self-reported. No technical documentation or live product evidence provided.

• The description claims LightScroll treats behavior change like a multiplayer game instead of a single-player one.
• It positions itself as an alternative to existing screen-time tools that are described as “utilities you dreaded opening.”
• The app is said to be built around social accountability, not just personal willpower.
