Duality Wallet vs Ecash App

Cash on your phone. As simple as Apple Pay, as fast as a text message, and as open as email. Duality is a self-custodial wallet that finally makes bitcoin feel like money you can actually use. Spend it, send it, get paid in it, in seconds, with no bank or middleman taking a cut. MONEY THAT MOVES LIKE A MESSAGE Payments settle over the Lightning network in seconds, not the three-day "pending" you're used to. Send, and it's done. TWO POCKETS, ONE WALLET Keep a Digital Cash balance to spend day to day, and a Bitcoin balance to hold. Swipe between them, and convert one to the other in a tap. GET PAID LIKE EMAIL Claim your own Lightning address: you@dualitywallet.money. Anyone, on any Lightning wallet, can pay you. No app lock-in, no account numbers. PAY IN A TAP Tap to pay over NFC, or scan any QR code with Quick Pay. Save the people and places you pay often as Favourites and settle up in two taps. SIGN IN WITH A PASSKEY, BACKED BY YOUR RECOVERY PHRASE Create and unlock your wallet with your fingerprint or face, with no password to remember. Your recovery phrase is the backup that always works: save it when you set up, and it restores your wallet on any device, whatever happens to your phone. YOUR KEYS, YOUR MONEY Your keys are generated on your device and never leave it. There's no account, no email signup, and no company that can freeze, spend, or block your balance. No analytics or tracking, in the app or on our site. SECURED BY BITCOIN Duality is built on Spark, a bitcoin layer 2, using the Breez SDK. Your money is secured by the most open, decentralised monetary network there is. Value you hold directly, not an IOU. Money without middlemen. Download Duality and try it today. Self-custodial means you're in control and responsible for your own access. Bitcoin's value can go up and down. Duality is not a bank and does not offer insured deposits.

Ecash App is an open source, transparent Fedimint wallet. It is an easy to use payments wallet, but allows for power users to access the full suite of Fedimint features. It works with every federation. Join a federation, hold ecash notes on your device, and pay. There is no account to create and no sign-up. WHAT YOU CAN DO • Pay and receive over Lightning — scan a QR code, paste an invoice, or open an LNURL link. • Claim a Lightning Address, so anyone can pay you at a name that reads like an email address. • Send and receive on-chain bitcoin, and watch deposits as they confirm. • Hand ecash to someone directly, as a string of text, with no payment network in between. • Discover federations over Nostr, and preview one before you join it. • Keep balances in several federations at once and switch between them. • Find nearby merchants that accept bitcoin, using BTC Map. • Sync your friend's payment information using Nostr • Lock the app with a PIN. NOTHING HIDDEN • Every fee, itemized, before you confirm a payment. • The Lightning gateways a federation has registered, and the one your payment will route through. • The on-chain UTXOs the federation holds. • The denominations of the ecash notes making up your balance. BACKUP AND RECOVERY Your wallet comes from a standard seed phrase. Write it down once, and you can restore your balances on another device. Recovery walks through each federation and restores what it finds.
