Lock In Squad vs Science Explorer

Lock In Squad blocks the apps that pull you away while you're locked in, on your own or together with your friends. Pick your apps, start a timer or a stopwatch, and they stay blocked until you hold the Lock Out button. BLOCKING • Pick apps, whole categories such as Social or Games, and websites in Apple's Screen Time picker. • Choose Block these apps, or choose Allow only these apps to keep up to 50 apps open while every other app and website stays blocked. • Set up to five schedules, such as weekdays from 9 AM to 5 PM, and your apps lock at those times even with Lock In Squad closed. • When a timer reaches zero, your apps stay blocked until you lock out. • To lock out, you hold the button for 1 to 30 seconds, however long you set, which gives you a moment to change your mind. • On iPhone, a Live Activity keeps your lock-in time on the Lock Screen. FRIENDS • Add friends by name or user ID, or share a link that adds you as a friend. • Start a group lock-in and follow the live standings while you lock in together. Invite friends in the app or with a link. • Give a group lock-in set times. Everyone who accepts them has their apps blocked at those times, and that time counts in the group's standings. • Keep a friend streak going on the focus days you share. • Like your friends' longer lock-ins, streak milestones, and group wins in Activity. • A glowing dot on a friend's picture means they're locked in right now. Send a nudge to a friend who hasn't started yet, or a cheer to one who has. • The weekly leaderboard ranks you and your friends by time locked in, and each week's winner wears a crown all the next week. PROGRESS • Your streak counts only the focus days you pick on the Block tab. • Share your streak, your week or a group win as a card made for stories, with a link that adds you as a friend. • Set a daily goal from 15 minutes to 8 hours on the Block tab. Your profile shows how close you are today, and its heatmap marks the days you hit it. • Your profile charts your focus time over 7, 30 or 90 days, a year or all time, next to a heatmap of the days you locked in. • Home Screen and Lock Screen widgets show your lock with your streak or today's minutes. On a focus day you haven't locked in, the lock gets more worried as midnight gets close. • Reminders come from your lock, in its own voice, and switches in Settings turn them off by type. THE SHOP Each minute locked in earns you one minute for the Shop. Give your lock a body color, face, hat and top, pick a background and a button color, and save up for safes from a piggy bank to a vault door. Your safe's door shuts when you lock in and opens when you lock out. You can also watch an ad for 10 bonus minutes. A friend who signs up with your referral code gets 1,000 minutes, and you get 1,000 after their first lock-in. PRICE Lock In Squad is free to use. An ad can show when you end a stopwatch lock-in or quit a timer early, but never when you finish a timer. Premium is a single payment, with no subscription. It removes ads and comes with the Diamond safe and a Premium badge next to your name. Lock In Squad runs on iPhone and iPad, and blocking apps needs iOS 16 or later. It works with VoiceOver and has a dark mode in Settings. Start as a guest, then sign in with Apple, Google or email to keep your progress, see your stats and add friends.
