FocusLock helps you block distracting apps, protect focused time and build healthier screen habits without sending your rules or usage data to our servers. SMART APP BLOCKING Choose apps, categories and websites, then create recurring schedules by weekday and time. FocusLock uses Apple's Screen Time frameworks to enforce the restrictions you configure. STRICT MODE AND DAILY QUOTAS Prevent impulsive edits while a strict rule is active, with a deliberate emergency-unlock safeguard. Prefer flexibility? Set a daily allowance and optionally reduce it week by week. FOCUS FROM ANYWHERE Start a focus session from a Home Screen widget, Control Center, Siri, Shortcuts or Spotlight. Follow the countdown on the Lock Screen and Dynamic Island with Live Activities. On iOS 26, AlarmKit provides a resilient system countdown and completion alert. SEE REAL PROGRESS Review focus minutes, completed sessions, block counts, streaks and achievements. The Screen Time report shows the activity data Apple makes available directly on your device. PRIVATE BY DESIGN Family Controls selections stay on each device. Rule metadata and focus history can sync through your private iCloud account. FocusLock includes no third-party analytics, advertising or tracking. HIGHLIGHTS • Scheduled app, category and website blocking • Strict mode and emergency-unlock safeguard • Daily quotas with progressive reduction • Focus timer linked to an existing lock rule • Widgets, Live Activities and Control Center control • Siri, Shortcuts, Spotlight and Focus Filter support • Custom Screen Time shield and activity report • Achievements, streaks and shareable weekly reports • 50 App Store languages and automatic language detection • Light, dark and iPad layouts Some Screen Time features require Family Controls authorization.

Verdict
The clearest difference is price: CHM Sharp at Free against FocusLock's $0.99. CHM Sharp also leads on iOS requirement (14.0 vs 17.4). FocusLock's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.
