ScreenFine

ScreenFine is an iOS app designed for adults who struggle with screen time limits. It enforces OS-level locks on selected apps once a daily usage limit is exceeded, requiring users to complete verified physical activities like pushups or steps to regain access. This approach leverages loss aversion and pre-commitment to change behavior effectively, offering a $1/week subscription with a 7-day free trial.

Who is it for?

Adults who have tried friction-based screen-time tools and want real consequences to reduce phone use

Problem

Many screen-time apps rely on reminders or dismissible timers that users easily bypass, failing to create meaningful consequences for overuse. Users often ignore limits, leading to excessive screen time without real behavior change.

Solution

ScreenFine uses Apple's Family Controls to lock apps at the OS level once limits are exceeded, requiring users to complete verified physical activities like 25 pushups or 1,000 steps to unlock apps. An AI villain provides personalized roasts to reinforce loss aversion and accountability.
