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.
Lightning Piggy has no backend of its own - there's nothing for us to track. The app is serverless: it talks directly to public Nostr relays and the Lightning Network. Your keys, your sats and your data stay on your device, under your control.
