Ttorang - Brain Training
Memory, focus & math daily
Free · Designed for iPad. Not verified for macOS.
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.
