Sentinel is an Android app which lets you safely watch over your Trezor transactions. Scan one or more of your account publics keys (XPUBs) and Sentinel will keep a close watch, alerting you of any new incoming transactions. It also allows you to generate new receive addresses, so you can receive bitcoin payments directly into selected Trezor account. Sentinel cannot create transactions or send your bitcoins, it is only useful as a watch-only wallet.

If your camera doesn't work, select Manual option instead and type the public key in. After you confirm it, Sentinel will download all transactions related to the imported account.
You can get more information about the particular transaction by simply selecting it from the list. To generate new receiving address, click on "+" icon at bottom right corner.
