SimpleEye Bluetooth Weight Scale is currently compatible with the following Bluetooth weight scales:

Android Device Compatibility: SimpleEye Bluetooth Weight Scale has been tested and verified with Android 2.0 (Motorola® Droid on Verizon®), 2.1 (LG® Ally on Verizon® and T-Mobile® myTouch 3G Slide running HTC® SenseUI) and 2.2 (Google® Nexus One on T-Mobile®). Some minor issues that should not prevent measurements from being taken have been observed with Android 2.1 devices running the HTC® Sense UI: the Bluetooth implementations on these devices have unresolved errors.

Setting up the connection between your weight scale and your mobile device.

When the application is first started, it will check if this is the very first time the application has started or if the application has been updated since it was last started: if either of these is true, it will display a list of changes as shown in Figure 1 below.
