BTC Balance Checker

Open source · Windows · macOS · Linux

Your address list, checked every minute.

Load hundreds of Bitcoin addresses. The app checks them on a loop and sends one Telegram or email alert the first time a balance appears. Keys never leave your machine because there are no keys: addresses only.
