Lock&Learn

Read full description

Be the one at the table who actually knows the answer. Lock&Learn turns your Lock Screen and Home Screen widgets into a tiny trivia game, played in the glances you already take a hundred times a day. A short question waits on your widget. You take a guess, and one tap reveals the answer, along with the true, carefully checked fact behind it. No accounts. No streak anxiety. Just a small "oh, really?" every time your screen wakes. HOW IT WORKS - A question appears on your widget, drawn from the topics you pick - Take your best guess - Tap to reveal the answer and the fact behind it - Questions rotate on your schedule, from every 15 minutes to every few hours THE FEED Open the app and keep going: the Learn tab is questions and facts as a full-screen feed, one card at a time. Tap to flip a card, swipe up for the next, swipe left to save it, swipe right when you already knew it. The scroll you reach for anyway, made of things worth knowing. QUIZ The Quiz tab turns the same cards into a game. A question, three answers, a ring draining while you decide, and the fact behind the answer the moment you pick. Rounds play back to back, a streak counts the ones you get in a row, and every question is written with its own answers, so the right one is never the obvious one. PREFER JUST THE FACTS One tap flips your widgets from questions to facts, so every glance is a quiet discovery instead of a challenge. Your call, any time. CHOOSE YOUR TOPICS Space, History, Human Body, Ocean, Psychology, Food, Animals, Planet Earth, Science, Sports, Arts and Music, Inventions. Switch on anything you are curious about and the questions rotate through all of it. MADE TO BE CALM - Notifications are off by default, and stay opt-in - Your progress stays on your device, no account needed - Save the questions and facts you love, and file them into custom lists of your own - A calm, paper-like design that reads beautifully in light and dark YOUR PROGRESS A Progress screen in the Library counts the facts you know and the facts you have met, keeps your streaks, and fills one bar per topic. A quiet answer to how it is going, with no dashboard in sight. LOCK&LEARN+ Every topic opens with a free preview, and another question unlocks each day at no cost. Lock&Learn+ opens all of them at once, along with every topic we add next. Take it yearly or monthly, or pay once and keep it for good. Every answer is checked against reliable sources before it ships, and new questions land every month. Lock your phone. Learn something anyway. Lock&Learn+ is available as a yearly or monthly subscription, or as a one-time lifetime unlock. Payment is charged to your Apple Account. A subscription renews automatically unless canceled at least 24 hours before the end of the current period; manage or cancel it any time in your Apple Account settings.
