saw this post #1294752 here on sn about a dad making Bitcoin Pokemon cards for his 4yo.

So I built an entire app around it.

Lil Satoshi - an educational app where parents & educators can create, customize, and print Bitcoin trading cards to teach kids about Bitcoin.

full customization to match your kid's age. supports P2PKH, P2SH, P2WPKH, P2WSH, P2TR address types with BIP39 mnemonics in 10 languages. print actual cards or save to gallery.

app is live on Play Store (closed testing), iOS App Store (TestFlight), and Zapstore

ps: it's free and works completely offline.
