Bitcoin Piggy Bank

Bitcoin Piggy Bank is a watch-only savings tracker that helps kids see their Bitcoin grow toward a goal — like a digital piggy bank on the kitchen counter. Parents set it up once with a public Bitcoin address from any wallet (Sparrow, BlueWallet, Coldcard, and more). Kids get a friendly home screen with their balance, a filling piggy bank, and progress toward goals like a bike, trip, or allowance jar. The app never holds private keys and cannot spend funds. WATCH-ONLY & FAMILY-SAFE • Public addresses only — no seed phrases or private keys • Optional parent PIN for editing banks and settings • Optional iCloud backup to sync piggy banks across your iPhone and iPad • Local deposit alerts when new sats arrive or milestones are hit MADE FOR KIDS, BUILT FOR PARENTS • Multiple children and multiple piggy banks per child • Savings story timeline with deposit history • Receive tab with QR code to share with grandparents • SatsCard NFC import for Coinkite cards • Home screen widget for a quick balance glance • Allowance tracker to compare expected vs actual deposits Bitcoin stays on the blockchain. Bitcoin Piggy Bank only shows what’s already public — in a way children can understand and parents can trust.
