The Rabby Mobile Wallet is good for signing transactions and contains security features that assist users in understanding the transaction details in order to avoid different sorts of fraud. But the Users Interface is considered to be too simple and lacks a lot of features as compared to other Mobile wallets. This also makes it difficult to use, which is the case with Face ID login not being switched on by default. But even with these concerns, it’s still an acceptable Wallet solution and may get better in the future considering it’s a new one.
