BlueKeys

BlueKeys scans nearby BLE devices, let you choose which is the BLE lock you want to unlock, and use the password/key you supply to open the lock, if everything is good, the App saves the key and will use it to unlock the lock in future. You can also enable the auto unlocking feature in the settings, it can unlock the lock automatically when the App is running in background and the saved BLE lock is within range. The saved keys/locks configuration can be exported to your iWatch, so you can click on iWatch to unlock the locks, but the auto unlocking feature is not available on iWatch due to the limits on WatchOS.

BlueKeys利用你提供的密码去打开附近的蓝牙锁，如果App在后台运行，并且后台自动开锁功能已打开，当保存的目标蓝牙锁出现在手机周围时，BlueKeys将会自动开锁，解放你的双手。你可以将保存的蓝牙锁的信息导出到iWatch上去，把iWatch当成开锁的钥匙，不过由于WatchOS的限制，后台自动开锁功能在iWatch上不可用。
