Hey Hunters! Milan here — 12 years old, from Slovakia 🇸🇰
I built Achive because every productivity app I tried failed the same way — streaks reset, dopamine wears off, no real cost to quitting. So I flipped the model.
You lock real money (5–500 €) on any goal. Upload daily proof. Complete every day → get 95 % back. Miss a single day → 100 % goes to a verified Slovak charity. Never to me.
It's Kahneman's loss aversion (2× stronger than reward gain) applied at the exact moment your motivation dies.
I coded the whole thing myself — React web + native iOS/Android + Firebase + Stripe. Payments run through a company account in my mother's name (I'm 12, obviously — she's legally responsible).
Would love your honest feedback on the mechanism, not just the app. Especially: where does it break? Who is it NOT for?
First stake is on me if you want to try — DM me here or milan.zvarik000@gmail.com.
Thanks for looking! 🙏
