Bam

Lapka BAM is a beautifully designed accessory for your phone that estimates blood alcohol content from a breath sample and allows you to track your measurements over time, compare them with friends and shape the party. The device fits in your palm, and when you hold it in a fist, the edge of your hand becomes the mouthpiece. The device is wireless — no synchronization is required. It calibrates automatically and professionally via Lapka servers using your device ID.
