About this app

BrainWave turns the reading your child is already doing into rewards you
control.

You write the lessons. Paste a chapter, import a file, or draft one with AI -
then review every word before your child sees it. Add a quiz, decide what it
is worth, and publish it when you are ready.

Your child reads it on their own tablet, answers the questions, and earns the
points you priced. Nothing you have not published ever reaches them.

HOW IT WORKS
- Sign in with Google and name your household
- Add your children, and invite the other parent with a link
- Write a lesson, or draft one with AI and edit it
- Give it a quiz - or several, each worth what you decide
- Pair your child's tablet by scanning a QR code
- They read, they answer, they earn

YOUR CHILD NEVER SIGNS IN
No account, no email, no password, no birth date and no photograph. Their
tablet joins your household by scanning a code you show it. There is no chat,
no social feed, and no way for anyone outside your family to reach them.

NO ADS, EVER
No advertising anywhere in the app, and no analytics or tracking on any screen
your child sees. Nothing is sold or shared, and nothing is used to train an AI
model.

REWARDS YOU SET
You decide what each quiz is worth, what a chore earns, and what those points
buy - screen time, a treat, whatever you agreed at home. A quiz marks itself
and pays out straight away, so nobody waits on a grown-up. Chores you set to
need approval, and every reward, wait for you.

AI IS OPTIONAL
BrainWave can draft lessons and quiz questions using an API key you bring from
Google Gemini, Groq, OpenRouter, Cerebras or Anthropic - most have a free tier.
It is used for writing only: it is never given your child's name, answers or
progress, and every draft is shown to you before anything is saved. You can
write every lesson yourself and never add a key at all.

READS OFFLINE
A lesson your child has already opened can be read again with no signal.
Finishing a quiz needs a connection, because the points are awarded by the
server.

FREE
No subscription, and nothing to buy inside the app.
