Less scroll. More life. The Pact turns "put the phone down" into a deal between two people who care about each other: your kid or your partner. Pick a small challenge together, a real reward, and sign it. HOW IT WORKS • Choose the challenge: a daily limit, a phone-free window (like dinner), app-free days, or a limit plus an activity, like reading a chapter. • Whoever takes it on picks their apps with Screen Time on their own iPhone. The selection never leaves their phone. • Each kept day is stamped on its own when Screen Time records it in full. Missing data never counts as kept: you review it together. • Reach the goal and the reward unlocks. The giver confirms they delivered it, and the winner confirms they got it. MADE FOR AGREEING, NOT SPYING • Suggest another limit or reward before signing. • Mutual pacts for couples: you both take it on and share the reward. • A gentle heads-up near the limit, without naming the app or the reward on the lock screen. • No GPS, no messages, no required photos. ONE PLAN FOR THE WHOLE HOUSEHOLD One plan covers the plan holder, one invited adult and up to six kids. Yearly with 7 days free, monthly, or pay once. Each of you uses The Pact on your own iPhone, with your own Apple Account. The Pact doesn't block apps or measure exact minutes: it relies on each iPhone's Screen Time data and on trust between you. Subscriptions renew automatically until canceled in your Apple Account settings.

Verdict

The call

The clearest difference is in-app purchases: Laifen at none against The Pact's 3. Laifen also leads on iOS requirement (15.0 vs 17.4). The Pact's advantage is update cadence (every 2 days vs every 3 weeks). On price, ads and device support there is nothing between them.
