Checked on 2026-10-27 against the official site, docs and app-store pages.

## What is Bither

Bither is an open-source Bitcoin wallet for iOS and Android, developed since 2014. A phone can run it in Hot mode (online SPV wallet) or Cold mode (offline signer); the two communicate by QR codes so the private keys of a Cold wallet never go online.

## Who holds the keys

| Parameter | Details |
|---|---|
| Key control | Self-custody: keys are held by the user on the phone; in Cold mode they stay on an offline device. |
| Account model | Hot (online) and Cold (offline) wallets linked by QR codes; SPV Bitcoin client with no account or server-held keys. |

## Features and supported networks

| Parameter | Details |
|---|---|
| Platforms | iOS (App Store) and Android (APK from bither.net); no Google Play version since 27 May 2025; desktop client discontinued in 2020 |
| Supported networks | Bitcoin |
| Connectivity | SPV peer-to-peer Bitcoin client |
| Privacy (CoinJoin, Tor) | Built-in private password keyboard so third-party keyboards never see the password (Android) |

## Security and audits

- Open source: the Android and iOS apps are published on GitHub under the Apache License 2.0.
- The Android APK is distributed from bither.net with SHA256 checksums.

## Questions and answers

Yes. Keys stay on the user's phone, and in Cold mode on an offline phone that signs transactions via QR codes.

**Is Bither open source?**

Yes. The Android and iOS apps are on GitHub under the Apache License 2.0.

**Which coins does Bither support?**

Bitcoin only.

**Where can I download Bither for Android?**

Only as an APK from bither.net; Bither left Google Play on 27 May 2025, and apps there using its name are a fake-wallet risk.

## How voting works

Votes are anonymous and carry no text. Each device has one vote per item; press the same button again to remove it. Cloudflare Turnstile checks that a person is voting. We keep a random device ID in a cookie and a salted hash of the IP address to limit abuse — no names, no accounts. Votes are visitors’ opinions, not investment advice.
