I'm not sure if my Bitcoin wallet is working, is there a way to check that it's ready to go? I'm using Breadwallet for iOS.
breadwallet is a standalone bitcoin client for mobile devices. There is no server which can get hacked or go offline, so you can always access the funds stored on your phone.
Using SPV mode, breadwallet connects directly to the bitcoin network with the fast performance you need on a mobile device.
Since the wallet itself has no indicator for connections and does not synchronize the blockchain, I would suggest that you use a very tiny amount of Bitcoin and send it in a micro transaction to your breadwallet to test if you are set up and connected.
By the way, did you backup your wallet yet?
If there is lack of indicators in the software and lack of documentation you can always send some small amounts of bitcoins to your public key from another key.
If it's connected and synced, you're ready to go.
