I couldn't focus for 5 minutes, so I built an app that seals my screen into what I'm studying

Hey IH 👋

For years I couldn't sit down to study for more than five minutes without drifting to YouTube or my phone. I tried every focus app out there, but they all shared the same flaw: you can switch them off in two clicks — so in a weak moment, you do.

So I built the tool I actually needed. bunqr turns your Windows PC into a sealed study room: you pick a website or a PDF, set a timer, and it blocks the rest until the time's up — with just enough friction that you don't quit on impulse. It's built for studying specifically, not generic productivity: exam countdown, Pomodoro breaks, focus streaks. No account, no ads, everything stays on your computer.

It's brand new — one-time €12.99 with a 7-day free trial, Windows only for now. I built it solo and I'm just starting to put it out there.

I'd love your honest feedback: getbunqr.com. And a question I keep wrestling with — what would make YOU trust a "focus app" enough to pay for it, even once?
