Ask anything. Watch a short video. Remember it for good. Doodlo turns curiosity into short, illustrated video lessons, and helps you actually remember what you learn. BUILT FOR ADHD BRAINS Long videos and walls of text lose a lot of us. Doodlo keeps it short: a lesson takes a few minutes, captions are on from the start, chapters let you jump around, and quick questions keep you in it. Doodlo is a learning app, not a medical product; it does not diagnose or treat any condition. DISCOVER Swipe through a feed of bite-size animated lessons on science, history, tech, money and more. Subtitles are on by default, and after each video a quick "Guess what?" question checks what stuck. CREATE YOUR OWN LESSON Type what you're wondering about. Doodlo writes, narrates and illustrates a video lesson just for you, in the style you pick: cartoon, lecture, cinematic 3D, or one you describe yourself. We'll let you know when it's ready. Every lesson ends with a 5-question quiz, and each question can take you back to the right moment in the video. REMEMBER IT Add any lesson to your memory and its questions become review cards. A modern spaced-repetition algorithm brings each card back right before you'd forget it: a short daily review, a weekly recap, and reminders that ask you a real question. Memory rings show how much of each lesson has stuck. STAY ON A ROLL Keep your streak going (streak freezes save a missed day), earn badges, and climb academic titles from Curious all the way to Professor as you truly learn. LEARN WITH FRIENDS Add friends, compete in a weekly friends-only league, and challenge them to beat your quiz score. They can even play the challenge on the web. Share lessons as videos, and invite friends so you both get a bonus lesson. SHARE WHAT YOU MAKE Your lessons are private by default. If you like, publish one to Discover; it goes through automatic content and accuracy checks first. FREE AND PRO Watching, searching and reviewing are free, and you can create your first lesson for free. Doodlo Pro gives you 20 lesson creations every subscription period and lets you download lessons. Doodlo Pro is an auto-renewing subscription. Payment is charged to your Apple Account when you confirm the purchase. It renews automatically unless you cancel at least 24 hours before the end of the current period, and renewal is charged within the 24 hours before the period ends. You can manage or cancel it anytime in your App Store account settings. A NOTE ON AI Lessons are created with AI and checked automatically, but they can still contain mistakes. If something looks wrong, report it from the lesson. Doodlo is for ages 13 and up and is available in English and Turkish.
