Set hard app limits using built-in screen-time tools

Use iOS Screen Time or Android Digital Wellbeing to set a hard daily limit on each social media app.

Why it works

Built-in limits work by converting a recurring willpower decision into a structural one: you make the choice once (set the limit) rather than each time you open the app. When the limit triggers, the app becomes unavailable — the behavioral cost rises from zero to a deliberate override action. Most people do not override most of the time, which is the friction doing its work.

How to do it

1. On iOS: Settings → Screen Time → App Limits → Add Limit → select Social Networking → set daily total.
2. On Android: Settings → Digital Wellbeing → Dashboard → tap app → set timer.
3. Set the limit to the total social media budget (e.g., 2 hours) rather than per-app limits that can be gamed by switching apps.
4. Enable the PIN requirement for overrides so an override is a conscious action, not a reflex.

Evidence

A randomized controlled trial found that limiting Facebook, Instagram, and Snapchat to 10 minutes per platform per day significantly reduced loneliness and depression over three weeks, compared to a control group. (rct)

The Hunt et al. trial used a 30-minute-total limit; a 2-hour cap is a looser application and is less studied at that specific threshold.

Common mistake

Setting the limit but enabling easy override without a PIN, which collapses the friction to a single tap and restores the original behavior.
