Yes, you read that headline correctly. A startup is taking pre-orders for the BluFit water bottle (US$59) and you'll never need to guess how many ounces or liters of water you've sucked down during the day.
This latest innovation in the world of connected fitness tools is currently grabbing pledges on Indiegogo, and early supporters can nab one of the bottles for $49. Now why would you buy a $50 or $60 water bottle? Well, that app takes a lot of different data into account -- weight, age, temperature, and humidity -- to determine how much you should be drinking. You can set and monitor personal goals, and adjust your sipping based on how active you are during a day.
