Lockty helps you use your phone less without relying on willpower. It starts with a short conversation: your hours a day, your age and how you use your phone. Lockty shows you how many days a year go into the screen and builds a plan to get them back. RULES THAT HOLD β€’ Daily limit: decide how much time your distracting apps get each day. β€’ Opening limit: cap how many times a day you open them. β€’ Short sessions: only a few minutes each time. β€’ When time is up, the app is blocked behind a Lockty screen. MODES FOR EVERY MOMENT β€’ Schedule modes by time, start them when you arrive somewhere, or with an NFC tag. β€’ Add tasks: read, stretch, meditate… β€’ Strict Mode for when you want no excuses. FRICTIONS THAT MAKE YOU THINK Before unlocking, Lockty asks for a pause: breathe, write what you're opening it for, copy a phrase, solve a small challenge or read your own words. Every friction is made your way. YOUR DAY AT A GLANCE β€’ Focus, Detox and Checks scores. β€’ The apps that take the most time, and how your usage changes. β€’ History for every mode: what happened, what you unlocked and why. β€’ Widgets and a Live Activity with your unlock countdown. PRIVATE FOR REAL Lockty uses Apple's Screen Time API. Your usage data stays on your iPhone: Lockty doesn't see what you type, what you browse or your Screen Time data. No account to create. You can export your data to a file encrypted with your password. LOCKTY UNLIMITED Lockty is used with an Unlimited subscription, weekly, monthly or yearly. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period; you can manage and cancel it in your Apple Account settings.

Verdict

The call

The clearest difference is in-app purchases: PDF at none against Screen Time Limit's 5. PDF also leads on update cadence (every 4 days vs every 3 weeks) and iOS requirement (15.0 vs 18.0). Screen Time Limit's advantage is ads (none vs shown). On price and device support there is nothing between them.
