TaskLock is a to-do list, habit tracker and calendar for iPhone and Apple Watch with a built-in app blocker. Choose the apps that distract you, and they stay locked until you finish the task, complete the habit or the event ends. No "ignore limit" button: you stay focused until the work is actually done. HOW IT WORKS 1. Add a task, habit or event, or sync your Apple Calendar. 2. Pick the apps, categories or websites to lock: Instagram, TikTok, YouTube, games, anything you choose. 3. Opening a locked app shows a shield with the tasks still keeping it locked. 4. Check the task off on your iPhone or Apple Watch and the apps unlock. Locks are optional. Without one, TaskLock is a simple, fast to-do list. APP LOCKING • Lock until a task or habit is done, or for the length of an event, such as "Study" from 2 to 4 pm. • Lock single apps, whole categories like Social or Games, and websites. • Lock groups: save sets like "Social media" and assign them in one tap. • Start a lock later in the day. • Stay honest: a confirmation countdown before completing or removing a lock, and a daily limit on lock changes. Set it to "no changes" for strict mode. TASKS • One daily card with today's tasks, events and habits, other days a swipe away. • Timeline of everything past and upcoming, with filters. • Move missed tasks to today in one tap. Move or copy any task to another day. • Saved tasks for the things you add often. • Reminders, notes, links with previews, locations, search and Control Center quick add. HABITS • Every day, chosen weekdays or every N days, up to several times a day. • Streaks, a history strip and a progress page with rings. • Skip a day, change today only, or edit from today on while past records stay intact. • Tags such as "Morning routine": tasks and habits with the same tag stay together on the Home screen. CALENDAR • Two-way sync with Apple Calendar, including iCloud, Google and other accounts on your iPhone. • Private calendars that live only in TaskLock. • Timed and all-day events, repeat rules from daily to custom, reminders, locations and meeting links. APPLE WATCH, WIDGETS AND LIVE ACTIVITIES • Watch app: see today's plan, add tasks and events, and check off a task to unlock apps on your iPhone. Complications and Smart Stack widgets included. • Home Screen widgets, plus Live Activities on the Lock Screen and in the Dynamic Island. DESIGN • Minimalist, one main screen. Light and dark themes, nine accent colors or your own, alternative app icons. Available in 47 languages. PRIVACY • No account, no sign-up. Your data stays on your iPhone, and the app works offline. Optional backup to your own iCloud Drive. • App blocking runs on Apple's Screen Time framework. TaskLock cannot see what you do in other apps. PRICE Free to download. The free version limits how many tasks, habits and events you can create. TaskLock Premium removes those limits. Made for students, remote workers and anyone who wants their phone to wait until the work is done.
