LoggerLink!

Campbell Scientifics LoggerLink for iOS is a simple yet powerful tool that allows an iOS device to communicate with IP-enabled dataloggers (CR6, CR200X, CR300, CR800, CR850, CR1000, CR1000X, CR3000). The app supports field maintenance tasks such as viewing and collecting data, setting the clock, and downloading programs. If your mobile device and cellular modem are both on the AT&T network, communications between LoggerLink and the datalogger cannot be established.
