Track your actual usage for one week before capping

Look at your real numbers before setting a limit — most people significantly underestimate their social media time.

Why it works

Self-perception research consistently finds that people underestimate screen time by 20-50% relative to device-recorded data. Setting a cap without a data baseline risks setting a limit that is either too lenient (and leaves the problem unchanged) or too aggressive (and triggers reactance and abandonment). A one-week baseline converts the habit from invisible to visible.

How to do it

1. Enable Screen Time (iOS) or Digital Wellbeing (Android) without setting any limits during week one.
2. Review the weekly report without judgment — the goal is data, not guilt.
3. Identify your two highest-use apps and calculate the daily average.
4. Set your cap at 80% of current usage for week two — a challenging but achievable reduction.

Evidence

Self-monitoring and baseline data improve behavior-change outcomes across domains by making the target behavior visible and providing feedback on progress. Screen-time underestimation is well documented in observational research. (observational)

The Andrews et al. finding is about general phone use; the underestimation specific to social media may vary by app and user.

Common mistake

Setting a cap based on what feels like "a lot" (e.g., "2 hours must be plenty") without knowing your actual baseline — for heavy users, 2 hours may represent a dramatic improvement; for light users, a non-issue.
