Ratings and reviews

Works great! Might take 2 or 3 seconds longer to confirm a lightning transaction than other wallets. Hang on to your seed words in case they update the wallet on you. The Bull Bitcoin team is the best in the world for Bitcoin stuff. No joke. I highly recommend all of the Bull Bitcoin ecosystem. Install this wallet!😀

Bull is an excellent app, it's great way to use layer 2 and on chain in a unified way. you can even use a signer and import an xpub if you wish. Support are super helpful too.

Terrible app and even worse customer service. My funds were unavailable to me for 2 weeks and I had to put in 8 hours of work just to get my money back to my account because they aren't clear about which of your bank accounts can send money to the account. Fitting name to call it Bull bitcoin since it's actually bullsh*t. Avoid If you value your time and sanity.
