Ttorang - Brain Training

Ttorang is a brain-training app you can start instantly - no sign-up, no login, no ads. ■ Three kinds of daily training · Memory - card matching and sequence recall · Attention - a reaction-speed game: tap the moment the light turns green · Language & math - mental arithmetic and word-recall quizzes with answers explained Three difficulty levels; each round takes just 2-5 minutes. ■ One routine a day Every day Ttorang builds a routine with one game from each category. A progress ring shows how far you've come, and you can pause and resume anytime. Finish them all for a "done today" - streaks and badges (first session, 7 days, 30 days) turn it into a habit. ■ Cognitive score report Each session is scored 0-100 per category. See 7-day and 30-day trend charts and week-over-week change, at a glance. ■ Designed for older adults first Large-text mode, high-contrast mode, voice guidance (TTS) that reads instructions and results aloud, and generous touch targets. A few big buttons - no maze of menus. ■ Training reminder Pick a time and get a local notification on your device. Turn it off and everything still works. ■ Four languages Korean, English, Japanese and Simplified Chinese - even the word-recall quiz uses words in your language. Privacy is the architecture, not a promise Ttorang has no server and makes no network requests at all. Your training history, scores, and settings stay on this device and are never transmitted anywhere. No ads, no analytics, no tracking. Everything works the same in airplane mode. Important health notice Ttorang is not a medical device and does not provide medical diagnosis, treatment, or prevention. The cognitive score is a reference metric based on game results only - it is not a diagnostic or assessment tool for dementia, MCI, or any condition. If you have concerns about memory or cognition, please consult a doctor or qualified professional. Ttorang simply helps you keep an enjoyable brain-health habit.
