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 35+ mini-games train these 6 domains, a little every day. ◯ Training matched to you Answer four 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 ◯ 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 ・Ad-free, distraction-free ◯ What users say "I can finally keep a habit." "10 seconds in the morning resets my focus." "No ads means I actually stay in the zone." ◯ Subscription BrainDojo offers an optional subscription (BrainDojo Plus) for full access to all games and features.
