Weigh yourself quickly and easily with a Wii Fit Balance Board and Bluetooth enabled Android device. Weighing yourself is as simple as starting FitScales, syncing the balance board then standing still on the board when FitScales is ready. You can optionally sync your weight with RunKeeper and/or FitBit for easy tracking. FitScales makes for a convenient free (open source) alternative to costly high-tech bathroom scales. Suitable for both phones and tablets.
