QuizBot - Learn & Unlock - Kids earn screen time by completing brain-training games

by•
QuizBot turns screen-time battles into brain-training wins. Instead of blocking websites, kids earn browsing time by completing a 3-game challenge (Memory Cards, Rewrite Word, Logic Matrix). The platform tracks progress across 8 cognitive domains — memory, attention, logic, math, language — with adaptive difficulty that grows with each child.

Hey Product Hunt, I built QuizBot because I was tired of the daily screen-time fights at home. Traditional parental controls just say "no", and that always ends in frustration on both sides. So I asked myself: what if kids had to earn their screen time instead of being blocked from it? That's the whole idea behind QuizBot. When a child tries to open a blocked site or app, the system throws a 3-game challenge at them — Memory Cards, Rewrite Word, Logic Matrix. Finish all three, and they get browsing credits that last 24 hours. The role reversal is the feature: kids actually start asking to play the games. What I didn't expect was how the project would evolve. I started with a simple Chrome extension idea, but to track 8 cognitive domains per child across devices, I had to build a full backend. So QuizBot became a web app + Android app + Chrome extension, all syncing in real time on Firebase, with Stripe handling subscriptions and 18 languages shipped (RTL included). A few things I'm genuinely proud of: - Adaptive difficulty that grows with each child, never boring, never frustrating - Multiple child profiles per account, so one subscription covers the whole family - A parent dashboard that shows real progress, not just playtime - Sequential 3-game challenges that unlock 20 minutes of browsing per round I'd love honest feedback from this community — especially from parents, edtech folks, and anyone who's built something solo. What would make QuizBot more useful for your family? What's the one feature you wish existed when you tried to manage your own kids' screen time? Try it free at

A parent here, and this concept is genuinely clever. One thing that would seal the deal for me is a sibling mode where two kids can compete head to head in the same game, since mine already argue about who has the higher score on everything.

Thanks, !

A little sibling rivalry over who has the higher score is honestly the best proof that the games motivate kids :)

A competitive mode is exactly where we're heading — the plan is a separate multiplayer section with beloved classics like Tic-Tac-Toe, Ludo, Checkers and Connect Four, expanded over time with educational games across all 8 cognitive domains: math duels, word games for two or more players.

Lots of room for fun educational gameplay. And so kids without siblings aren't left out, we're exploring a strictly limited social layer — no real names, no photos, and a chat with emoticons only :)

Every child deserves a worthy opponent.

There's a 30-day free trial if you want to see the foundation today!

Love the trade-time-for-skills angle, way better than just blocking sites. One thing that would really help my household: a shared parent dashboard where my partner and I can both see progress and set weekly challenge goals, instead of just getting individual email reports we'd have to forward around.

Maker

Thank you, — a shared dashboard for both parents is a great point, forwarding email reports around is exactly the kind of friction we want to remove. It's on the roadmap. On weekly goals: while they can't be set directly as a number yet, you can already steer them indirectly — parents can raise or lower the number of challenge games a child must complete to unlock apps, and adjust the time after which the apps lock again. Combined, those two levers effectively shape the weekly rhythm. There's a 30-day free trial, so you and your partner can test the workflow together and tell us what else is missing!

This actually got my nephew to put down his tablet on his own for the first time. The adaptive difficulty feels smart, not just thrown in as a buzzword.

This made my day, İsmet — thank you! A child putting the tablet down on their own is exactly the moment QuizBot was built for. And glad the adaptive difficulty feels real: it tracks 8 cognitive domains per child and adjusts continuously, so it's never boring, never frustrating. Give your nephew a high five from us :)

The 3-game challenge sounds fun, but could you add a multiplayer mode where siblings or friends can compete on the same cognitive challenges in real time. That would turn solo brain training into a social thing and probably keep kids coming back longer than just grinding for screen time on their own.

You're already the second parent here asking for multiplayer, Hamide — and we hear you! The vision is a dedicated section with classic games like Tic-Tac-Toe, Ludo, Checkers and Connect Four, expanded with educational head-to-head games in all domains: math races, word battles for 2+ players. You're right that social play keeps kids coming back — that's exactly why it's high on the list. And for children without siblings, we're exploring a heavily restricted social network: no real names, no photos, no chat, only emoticons — so everyone can find an opponent safely. Real-time sync already powers the whole platform, so this is a natural next step. Try the current version — it's free for 30 days!

Thank you all for the warm welcome and the amazing feedback — you're already shaping the roadmap!
