AddressGuard Bitcoin

Compare the address you trust with the address you are about to use before an irreversible Bitcoin send. AddressGuard Bitcoin gives you one clear Check screen with two fields: Original address and Address to check. Paste, scan, or choose a photo for each address, then compare them character by character. The result is plain: - Addresses match - Do not send — characters are different When addresses differ, AddressGuard highlights the exact positions so you can inspect them yourself. Technical format, network, and checksum details remain available in a collapsed section when you need them. Your first three comparisons are free. AddressGuard Pro is a one-time lifetime purchase that adds unlimited comparisons, saved trusted addresses, full local History, and export. There is no subscription or trial in the current app. The app has three tabs: - Check — compare two Bitcoin payment targets - Saved — switch between saved trusted addresses and local History - Settings — help, privacy, terms, alerts, accessibility, Pro, restore, and export Privacy by design: - No account - No analytics or advertising SDK - No crash-reporting SDK - No network calls - Comparisons, Saved, and optional History stay on this device unless you choose to export AddressGuard supports on-chain Bitcoin addresses, Lightning invoices, Lightning Addresses, and LNURLs. It validates supported formats locally and does not resolve Lightning Addresses or LNURLs over the network. AddressGuard never connects to a wallet, asks for keys or seed phrases, holds funds, signs a transaction, sends money, or broadcasts a payment. It compares public payment targets you provide. Important: AddressGuard can help you spot differences. It cannot guarantee fund safety, prove who controls an address, prevent every loss, recover a wrong send, or replace your normal transaction review.
