Android

download the APK

Download the latest APK from GitHub and install it. Android will ask you to allow installing from your browser the first time - that's expected for apps outside the Play Store. Every build is open-source and published straight from our GitHub Releases, so you can see exactly what you're installing.

Private by design

No tracking. No servers. No accounts.

The Lightning Piggy Family App has no backend of its own - there's nothing for us to track. It isn't a wallet and never holds your funds: it connects to wallets you choose (custodial or self-custodial) and talks directly to public Nostr relays. Your keys and sats stay in your wallet, and your data stays on your device, under your control.

Everything in one app

Multiple wallet connections

Connect a separate wallet for each member of your family - Alice's savings, Bob's pocket money, or Jack's holiday savings.

Save in sats

Watch real Bitcoin savings grow together, in a wallet you connect.

Send & receive

Easily monitor and control your wallets for the whole famliy.

Transfer & swap

Using NWC, move sats between wallets, and swap between on-chain and Lightning.
