## What is BRAIQTH?

The more you learn, the stronger you get.

BRAIQTH turns studying into a battle. Every question you answer deals damage to the enemy — answer faster and keep your combo alive to hit harder. One more question is never quite enough.

■ 13 subjects
- Irregular verbs (English)
- Vocabulary battles (English, Chinese, Malay)
- Sentence battles (English, Chinese, Malay)
- Fill-in-the-blank battles (English, Chinese, Malay)
- Math
- Science
- Geography and history

■ 15 seconds of focus
Each question has a 15-second limit. The screen pulses red in the last 5 seconds, and answering within 3 seconds shows your exact time and deals 1.5x damage. Questions you get wrong come back later in the same battle, so nothing stays half-learned.

■ Collect as you learn
Win a battle and a treasure chest opens. There are 48 weapons across four rarities; duplicates turn into shards you can spend, with coins, to level a weapon up. Your avatar combines 10 characters with faces, items and pets, and evolves as your level rises.

■ Compete with friends
- Online battles: share a room code, or match at random
- Weekly, monthly and per-subject rankings
- 43 achievement badges
- Friend list

■ See your progress
Accuracy, day streaks, average answer time, a 14-day history and your strongest and weakest subjects, all in plain numbers and charts.

■ Four languages
Japanese, English, Simplified Chinese and Malay. Pick your native language and the app builds questions between it and the language you want to learn.

■ Accounts are optional
Every subject is playable without an account. Creating one adds progress backup, syncing across devices, rankings, online battles and friends. Sign up with an email address and a password.

■ About ads
The only ads are optional rewarded videos in the Shop ("watch a video to earn points"). There are no ads during battles or on result screens. Ads are non-personalized and rated for all audiences, and we never track users across apps.
