Ttorang - Brain Training

About

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.
