Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 6.81 MB, so it installs quickly even on modest connections.
This build is signed by "Charles Hill" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

- By default double-spend transactions are broadcast to several web services simultaneously to improve chances of confirmation.

- Several address types - Legacy (p2pkh), SegWit backwards compatible, SegWit (bech32).
- Transaction history view where you can re-broadcast any past transaction, copy to clipboard any transaction as raw hexadecimal, or update any locally stored transaction by fetching it from the configured web service.
