Using the Bluetooth interface can be transferred to an iOS device, the data also. Install app, create user profile and send data. Works well. Here you also get graphical analysis of its measurements. People, which this is measured regularly as a help, you do not need handwritten notes in notebooks. If you want, you can publish his data in all networks in the online world. For me gimmick.
Nice that the required batteries are included. If you want to operate the unit with power supply, but must also reach into his pocket. However, a standard power supply is sufficient.
Conclusion: good meter with the possibility of data collection and analysis using App. Due to the ambitious but price only 4 points.
