Can't focus. Get distracted. Forget things. A daily 10-second brain training habit, for adults. ◯ Why handwriting? Research shows handwriting activates broad sensorimotor regions that tapping or typing cannot reach. ・Mueller & Oppenheimer (2014) — handwritten notes improve memory ・van der Meer et al. (2020, NTNU) — handwriting activates wider brain areas ◯ Train 6 cognitive domains ・Attention — sustained focus ・Memory — working and long-term ・Processing Speed — reaction and judgment ・Executive Function — planning, switching ・Language — reading, writing, thinking ・Visuospatial — spatial awareness 40+ mini-games train these 6 domains, a little every day. ◯ Training matched to you Answer five questions once. What you struggle with (staying focused, forgetting, planning, rushing into mistakes, reading and writing), how much time you have, and when you want to train — your daily set is built from that. ・Trainings that match your struggles come first ・Your daily amount follows the time you have ・Reminders are set for the time you chose ・Redo it anytime from Settings ◯ Brain Dojo Check Once a day, three quick tests measure Processing Speed, Inhibitory Control and Working Memory. Your result is shown as a rank from 10th Kyu to 10th Dan, with a radar chart. ◯ Built for adults who struggle to stay consistent ・Sessions start at 10 seconds ・Quiet by default — no pressure notifications ・Daily completion stamps ・Streaks won't shame you if you miss a day ・A weekly goal, so a missed day can be made up that week ・Start today's training straight from the Home Screen widget ◯ What users say "I can finally keep a habit." "10 seconds in the morning resets my focus." ◯ Free to use All trainings except the newest ones are free to play (with ads). With BrainDojo Plus, ads disappear and every new training is available anytime. ◯ Subscription BrainDojo offers an optional subscription (BrainDojo Plus) for full access to all games and features.
