Learning, without studying. Lumize turns what you want to learn into notifications on your lock screen: a Spanish word, a capital, a chemical element, a quote you want to live by. Lumes arrive throughout your day, at times you choose, so the moments you already spend on your phone become learning. Make your own collections, let AI build one on any topic, or start with a ready-made one from the Vault. LEARN FROM YOUR LOCK SCREEN Pick a collection, then choose how often and between which hours. Your lumes show up all day, and tapping one opens it in the app. Nothing to plan and no sessions to sit through: you learn effortlessly while you go about your day. CREATE ANYTHING YOU WANT TO LEARN Type what you want to learn, like "Spanish for my trip" or "the planets", and AI builds the collection for you. Or add lumes yourself, translate a collection or pull the vocabulary out of any text. Japanese, Chinese, Korean and more come with pronunciation in Latin letters. START WITH THE VAULT Import ready-made collections, from language courses to capitals, flags and the elements of the periodic table, plus facts worth knowing and mindset collections. Once imported, a collection is yours to change. PUT YOUR MEMORY TO THE TEST Once a lume has reached you three times, it's ready for recall. Type the answer from memory, ask for a hint when you need one, and watch what you know move to your archive. Included in Lumize Gold. LEARN AS YOU LISTEN Turn any collection into an audio session with spoken lumes and music. Ideal for your commute, a walk or the gym. Included in Lumize Gold. BUILD YOUR DAILY LINEUP Mix up to 8 collections into one schedule, so words, facts and mindset reminders take turns throughout your day. Included in Lumize Gold. SHARPEN YOUR MINDSET Keep the quotes, principles and reminders that matter to you close, and write down your reflections along the way. Your reflections stay private. LEARN TOGETHER Share a collection with friends, classmates or family. Let them follow your updates, build it together with you, or give them a copy of their own. LUMIZE GOLD Gold unlocks recall, audio sessions, your daily lineup, smarter AI lumes and colorful skies. Lumize offers an optional auto-renewing subscription for additional features. The price and billing period are shown before purchase. Payment is charged to your Apple Account.
