Hey Product Hunt 👋
I'm Sebastian, the solo maker of Braintoll.
A while ago I was trying to learn Spanish. I had a vocab app, a deck of words, and good intentions. What I didn't have was time, or so I told myself. Then I checked my screen time: over two hours a day, mostly Instagram and YouTube, mostly opened without thinking. I'd unlock my phone to check the weather and twenty minutes later I'd be watching someone restore a rusty knife.
App limits didn't help. I hit "ignore for 15 minutes" so many times it became part of the reflex. And my vocab app? I opened it maybe twice a week.
So I built a small thing for myself called VocabBlock: before Instagram opened, it made me answer a few vocab cards. That was all it did. It was ugly, it only ran on my phone, and it worked better than anything I'd tried. Not because it stopped me from scrolling, but because every time I reached for my phone, I learned something on the way in. Some days I'd answer the cards and realize I didn't even want Instagram anymore.
A few friends wanted it, one for exam prep, one for medical terms, so it grew into Braintoll:
• Pick the apps that should require a toll
• Build a card set: write it, import from Anki, or let AI draft one from a topic, text, or PDF
• When you open a tolled app, reveal each answer and rate your recall. Enough "Easy" cards and you're in, for a time limit you set
• Spaced repetition, so the cards you struggle with come back
Things I cared about:
• Privacy: Braintoll only knows which app is open. On iPhone it only gets Apple's private Screen Time tokens and never even learns app names
• Weekly schedules, so the friction only kicks in when you want it
• An honest exit: a "Keep my attention" button for when you realize you didn't need the app after all
It's free on Android and iPhone. Premium adds unlimited blocked apps and more AI generations.
I'd love to know: which app would you put a toll on first, and what would you learn on the way in?
