Ttorang - Brain Training
Memory, focus & math daily
Free · Designed for iPad. Not verified for macOS.
Five free brain trainings, now with Number sequence and Word memory. Pick Easy, Normal or Hard; today's training changes daily. Big text, voice guidance, no account.
Ttorang is a brain-training app you can start instantly - no sign-up,
no login, no ads, no payments. Every training is free.
■ Five kinds of brain training
· Card matching - find pairs of the same picture (20 pictures)
· Number sequence - numbers appear one by one; tap them in the same order
· Green light - tap the moment the light turns green (reaction speed)
· Math & word quiz - mental arithmetic and word recall, with answers explained
· Word memory - memorize a few words, then pick the ones you just saw
Together they cover memory, attention, and language & math.
■ Easy, Normal or Hard - at your own pace
On the All Training screen, pick any of the five trainings at the level
you like and play as often as you want. Start with Easy and move up to
Hard when you are ready. Each round takes just 2-5 minutes.
■ Today's training changes every day
Every day Ttorang builds a routine with one training from each area, and
the mix changes from day to day. Card pictures and words (40 per language)
are drawn fresh each round, so the same questions don't keep repeating.
A progress ring shows how far you've come, and you can pause and resume
anytime. Finish them all to build streaks and badges (first session,
7 days, 30 days).
■ Cognitive score report
Each session is scored 0-100 per area. See 7-day and 30-day trend charts
and week-over-week change at a glance - and send this week's record to
your family as a single picture.
■ 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.
■ Five languages
Korean, English, Japanese, Simplified Chinese and Traditional Chinese -
even the word questions use 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 training 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.
