Opifera is the Bank of Mom and Dad with real interest. You hold the money and set the rate. Your kid gets a real ledger, real goals, and a snowball they can watch roll. The earlier they start, the longer the hill.
Just looking? The demo is a shared sandbox that resets daily.

The snowball effect
“Start your snowball early, and find a long hill.”
after Warren Buffett
You hold the money and set the interest rate. A generous rate on a small balance is what makes compounding something a kid can actually feel.
Interest posts to their ledger every month. Then that interest earns interest too. The snowball picks up snow as it rolls, and your kid watches it happen.
Money habits form young: research finds they are largely set by around age seven (University of Cambridge, Whitebread and Bingham, 2013). Start now, and they get the longest hill they will ever have.

Rolling since last August. It grows as it rolls.
Every kid gets their own snowball chart: the money they added, and the money it earned all by itself. The gold is the part they did not lift a finger for. That is the moment compounding stops being a lecture and becomes something they saw.
Each kid picks a goal. A clear progress bar makes patience feel like progress.
Kids can lock part of their savings in a certificate of deposit and get it back with a bonus. Being paid to wait is a lesson most adults never got.
No bank connections and no real money in the app. The dollars stay wherever they live today; Opifera keeps the ledger honest.
